if a=b, what is the numerical value of the quantity a/b?

Answers

Answer:

The numeric value is 1.

Explanation:

We have given that the “a” equal to “b” which means we can replace the “a” with “b” or we can replace the “b” with “a”.  

The given condition or quantity = a/b.

Now it is required to find the numeric value of a/b.  

To find the numeric value we first replace the “b” with “a” and then divide the values. Since we know that if the numeration and denominators are the same then after dividing the value, the resulting value will be 1.

The numerical value = a/b = a/a = 1

The shape and volume of the cube and the liquid changed when the cube was placed in the bowl. The liquid stayed the same when it was poured from the bowl.

Answers

Answer:

When the cube was placed in the water, the volume of the water changed. When the liquid was poured from the bowl, the shape changed.

Explanation:

When a cube is placed inside water, the volume of the water will change due to the introduction of the cube as the cube will displace some water. Remember that the shape of a liquid is the shape of its container so the shape of the water remains the same.

When the water is poured into a glass, its shape changes as it now assumes the shape of the glass as explained above.

Answer: When the cube was placed in the water, the shape of the cube stays the same. When the liquid was poured from the bowl into the glass, the shape changed

A Moving to another question will save this response.

Answers

The correct answer is 0.72 g/cm3

Explanation:

The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:

[tex]d = \frac{m}{v}[/tex]

[tex]d = \frac{46 g}{64 cm3}[/tex]

[tex]d = 0.718 g/cm3[/tex]

This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3

The molar mass of CsF is 151.9 g/mol. How many grams of CsF are needed to prepare 300.0 mL of 0.0500 M CsF solution?

Answers

Answer:

2.28 g of CsF.

Explanation:

The following data were obtained from the question:

Molar mass of CsF = 151.9 g/mol.

Volume = 300 mL

Molarity of CsF = 0.05 M

Mass of CsF =.?

Next, we shall convert 300 mL to litre (L). This can be obtained as follow:

1000 mL = 1 L

Therefore,

300 mL = 300 mL /1000 mL × 1 L

300 mL = 0.3 L

Therefore, 300 mL is equivalent to 0.3 L

Next, we shall determine the number of mole CsF in the solution. This can be obtained as follow:

Volume = 0.3 L

Molarity of CsF = 0.05 M

Mole of CsF =.?

Molarity = mole /Volume

0.05 = mole of CsF /0.3

Cross multiply

Mole of CsF = 0.05 × 0.3

Mole of CsF = 0.015 mole.

Finally, we shall determine the mass of CsF needed to prepare the solution as follow:

Mole of CsF = 0.015 mole.

Molar mass of CsF = 151.9 g/mol.

Mass of CsF =.?

Mole = mass /Molar mass

0.015 = mass of CsF /151.9

Cross multiply

Mass of CsF = 0.015 × 151.9

Mass of CsF = 2.28 g

Therefore, 2.28 g of CsF is needed to prepare the solution.

Answer:

Explanation:

A student obtains a clean, dry graduated cylinder. She weighs the cylinder and finds the mass to be 32.64 g. She then fills the cylinder with a certain volume of water. She weighs the water-filled cylinder and finds the total mass to be 61.57 g. If the density of the water in the laboratory is 0.9975 g / mL , what is the volume of the water in the graduated cylinder?

Answer:

Volume of water =29.00mL

Explanation:

mass of cylinder (Mc)=32.64g

mass of water-filled cylinder (Mw+c)=61.57g

mass of water (Mw)= (Mw+c) - (Mc).

=(61.57 - 32.64)g = 28.93g

However:

Density = mass÷volume

hence Volume of water = mass of water÷density of water.

28.93g÷0.9975g/mL = 29.00mL

- Take 11.7mL of 6.0-M hydrochloric acid and subsequently add 88.3 mL of water to complete the 100.00 mL

Explanation:

Hello,

In this case, given that the dilutions are preparedfrom 3.0-M and 6.0-M hydrochloric acid, we must proceed as follows:

- 3.0-M stock: when using this stock, the aliquot you must take is computed as shown below:

[tex]V_1=\frac{M_2V_2}{M_1}=\frac{100.00mL*0.70M}{3.0M}=23.3mL[/tex]

It means that you must take 23.3 mL of 3.0-M hydrochloric acid and subsequently add 76.7 mL of water to complete the 100.00 mL.

- 6.0-M stock: when using this stock, the aliquot you must take is computed as shown below:

[tex]V_1=\frac{M_2V_2}{M_1}=\frac{100.00mL*0.70M}{6.0M}=11.7mL[/tex]

It means that you must take 11.7mL of 6.0-M hydrochloric acid and subsequently add 88.3 mL of water to complete the 100.00 mL.

Answer:

a) ²²⁴Ra₈₈ ---> α + ²²⁰Rn₈₆ + Q

b) the Q-value of this reaction is 5.789 MeV

c) the energies (in MeV) of the two associated alpha particles are; 5.69 MeV and 5.449 Mev

       

Explanation:

a)

The decay equation for the alpha decay is expressed as;

²²⁴Ra₈₈ ---> α + ²²⁰Rn₈₆ + Q

b)

Calculate the Q-value (in MeV) of this reaction.

Q = Mparent - Mdaughter -Mg

Q = MRa - MRn -Mg

= 224.020202 - 220.011384 - 4.00260305

= 0.00621495 amu

= 5.789 MeV

therefore the Q-value of this reaction is 5.789 MeV

c)

Energy of alpha particle is expressed as;

E∝ = MQ / ( m + M)

now this is the maximum energy available for the daughter, ²²⁰Rn going to the ground state;

The energy of the alpha particle gives;

E∝  = 220(5.789) / ( 4 + 220) = 5.69 MeV

as given in the question,The other less frequent alpha occurring 5.5% of the time leaves the daughter nucleus in an excited state of 0.241 MeV above the ground state.

Therefore the energy of this alpha is

E∝ = 5.69 - 0.241 = 5.449 Mev

Therefore the energies (in MeV) of the two associated alpha particles are; 5.69 MeV and 5.449 Mev

d)

Sketch of the nuclear decay scheme have been uploaded along side this answer.

(a)[tex]^{224}Ra_{_{88}}=^4\alpha_{_2}+^{220}Rn_{_{86}}+Q[/tex]

(b) the Q-value of the reaction is 5.789 MeV

(c) The alpha particles have energies of 5.69 MeV and 5.449 MeV

Alpha decay:

(a) The alpha decay of the radioisotope 224Ra is given by:

     

         [tex]^{224}Ra_{_{88}}=^4\alpha_{_2}+^{220}Rn_{_{86}}+Q[/tex]

(b) The Q-value  of a reaction is given by:

Q = {mas of reactants - mass of products}c²

[tex]Q = [M_{224Ra} - M_{\alpha} - M_{220Rn}]c^2[/tex]

Q = (224.020202 - 220.011384 - 4.00260305) amu.c²

Q = 0.00621495 × 931.5 MeV   ( since 1 amu.c² = 931.5 MeV)

Q = 5.789 MeV

(c) The energy of the alpha particle is expressed as;

E(α) = MQ / ( m + M)

it is the maximum energy available for the daughter nucleus, ²²⁰Rn going to the ground state.

If the daughter nucleus is at rest then all the energy is carried by the alpha particle.

The energy of the alpha particle is:

E(α)  = 220(5.789) / ( 4 + 220) = 5.69 MeV

Now, for the alpha particle occurring 5.5% of the time and leaving the daughter nucleus in an excited state of 0.241 MeV :

The energy of this alpha particle is

E(α) = 5.69 - 0.241 = 5.449 Mev

C. Chlorine does not exist as an elemental part, there is chlorine gas with two different chlorine atoms that results the atomic mass 35.45 amu.
D. As fluorine only has one isotope the atomic mass is identical to the mass of the isotope.

Answers

Answer:

B. Chlorine has more than one stable isotope that occurs naturally.

D. As fluorine only has one isotope the atomic mass is identical to the mass of the isotope.

Explanation:

The reason for the difference seen between the atomic mass provided in the periodic table and the atomic mass of each element is that most naturally occurring elements have more than one isotope (isotopes are atoms that have the same atomic number but different mass numbers). This means that when we measure the atomic mass of an element, we must generally settle for the average mass of the naturally occurring mixture of isotopes.

¹⁹F is the only stable isotope of fluorine, and its abundance is 100%. Therefore, its atomic mass is identical to that of the isotope.

On the other hand, chlorine has two stable isotopes ³⁵Cl (75.77%) and ³⁷Cl (24.23%). The atomic mass of  ³⁵Cl has been determined to be 34.96885 amu, and the atomic mass of ³⁷Cl has been determined to be 36.96590 amu. Thus, the average atomic mass  of chlorine can be calculated as follows:

average atomic mass  of natural chlorine = (0.7577)×(34.96885 amu) + (0.2423)×(36.96590 amu)  = 35.45 amu

Note that in calculations involving percentages, we need to convert percentages to  fractions.

Which species is oxidized in the following reaction? CO2 + H2 → CO + H2O A. H B. CO2 C. C D. O

Answers

it should be option A. H

[ because H gained oxygen ( O ) ]

Oxidation is defined by :

- the loss of electrons

- the loss of hydrogen ( H )

- the gain of oxygen ( O )

- increase in oxidation state

Reduction is defined by :

- the gain of electrons

- the gain of hydrogen ( H )

- the loss of oxygen ( O )

- decrease in oxidation state

(Basically, oxidation n reduction is opposite of each other)

The species being oxidized in the following reaction is Carbon Dioxide (CO2). This can be determined by looking at the oxidation states of the reactants and products.

What happens in case of reactants ?

In the reactants, Carbon Dioxide (CO2) has an oxidation state of +4, while Hydrogen (H2) has an oxidation state of 0. In the products, Carbon (CO) has an oxidation state of +2, and Water (H2O) has an oxidation state of -2.

The net change in oxidation states between the reactants and products is a decrease of 6, which means that the species that was being oxidized is Carbon Dioxide (CO2). The oxidation state of a species can be determined by looking at the number of electrons it has gained or lost in a reaction.

In this reaction, Carbon Dioxide (CO2) has lost 6 electrons, which is a sign that it is the species being oxidized. This is further evidenced by the fact that Carbon (CO) and Water (H2O) have gained electrons, meaning that they are the species being reduced. Therefore, the species being oxidized in the following reaction is Carbon Dioxide (CO2).

The complementary base sequence to GTAGCT is:_______.A) CATCGA.B) ACGATC.C) GCAGTA.D) AGTCGA.E) None of the above

Answers

Answer:none of the above

Explanation:

The complementary base sequence to GTAGCT is C-A-T-G. Therefore, option E is correct.

What is complementary base sequence ?

If the base sequence of the other strand is known, complementary base pairs allow the sequence of one strand to be predicted. In DNA, complementary base pairing is crucial because it enables the base pairs to be put in the most energetically advantageous configuration.

Reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template, creates complementary DNA (cDNA), a DNA copy of a messenger RNA (mRNA) molecule.

The nitrogenous bases' adenine, thymine, cytosine, and guanine are referred to as complementary base pairs. Adenine will always pair with its complementary base, thymine, and cytosine will always couple with its complementary base, guanine, in a double strand of DNA.

Thus, option E is correct.

Answer:

The main reason that NO, has a higher boiling point than CO is that NO has a larger molar mass.

The main reason that NH3 has a higher boiling point than CH4 is that NH exhibits hydrogen bonding.

The main reason that CS2 has a higher boiling point than CO2 is that CS2 has a larger molar mass.

Explanation:

The larger the molecular mass, the greater the surface area of the molecule and the greater the magnitude of dispersion forces. Hence, among nonpolar molecules, increase in molecular mass leads to a higher boiling point due to stronger dispersion forces.

Though CO and NO possess dipole-dipole forces, NO has a greater molar mass than CO, hence it has a higher boiling point than CO.

NH3 exhibits intermolecular hydrogen bonding hence it has a much higher higher boiling point than CH4 irrespective of the fact that their molar masses are close in magnitude.

What are the intermolecular forces between molecules in a liquid sample of sulfur trioxide,SO3?a. hydrogen bonding b. dipole-dipole interactions c. dispersion forces

Answers

Answer:

dispersion forces

Explanation:

SO3 is a trigonal planar molecule. All the dipoles of the S-O bonds cancel out making the molecule to be a nonpolar molecule.

The primary intermolecular force in nonpolar molecules is the London dispersion forces. As expected, the London dispersion forces is the intermolecular force present in SO3.

Hence SO3 is a symmetrical molecule having only weak dispersion forces acting between its molecules.

The intermolecular bond in the sulfur trioxide has been the dispersive force. Thus, option C is correct.

The sulfur trioxide has been the nonpolar molecule with the presence of S-O and S=O bonds.

The nonpolar bonds have consisted of weak intermolecular interactions resulting from the London Dispersive force. This type of interaction has been able to bind the nonpolar molecules together.

Thus, the intermolecular bond in the sulfur trioxide has been the dispersive force. Thus, option C is correct.

As you read what one person says about her job, imagine yourself doing this kind of work some day. How would you feel if every day you helped people make progress? I work closely with people who have hurt themselves. Their injuries may be as mild as having a sore shoulder, knee or back, or as severe as having paralyzed legs and/or arms. It's my job to evaluate what their problems are and come up with ways to help make them better, stronger, take their pain away or teach them to walk and do things for themselves again. I need to be able to communicate well with people of all ages and backgrounds everyday. I need to be able to talk to people I've never met and ask them personal questians that help me to understand what is wrong with them. I can't be shy around new people and I need to be clear in my communications with them. I chose to go into physical therapy because I love to be with people and talk with ther. I decided that I didn't want to use the computer all day or answer the telephone or be in a lab doing experiments. I wanted to be around people, and I wanted to be an important part of helping them feel better To prepare to become a Physical Therapist, I had to finish college and then go to graduate school for 3 years. In that time, I learned all the muscles in the body and all the organs and how they work, Ilearned how to figure out what is weak and what hurts on people and then how to help. I prepared for knowing all that by taking a lot of classes in biology, chemistry, math, physics, anatomy, physiology and psychology. What i like about my job is that it is always very interesting and never boring. I like that I am never alone but surrounded by geaple all the time. They tell me that I have made a difference in their lives and when I go home at night, I know that I have touched someone else's life and they appreciate the work I did for them. Talso love that my job combines being active and physical with being a thinker and doing a lot of problem solving. 3.
