1.20×10−8s to nanoseconds

Answers

Answer 1

Answer:

There are 12 nanoseconds in [tex]1.2\times 10^{-8}\ s[/tex].

Explanation:

We need to convert [tex]1.2\times 10^{-8}\ s[/tex] to nanoseconds.

We know that,

[tex]1\ s=10^9\ ns[/tex]

Now using unitary method to solve it such that,

[tex]1.2\times 10^{-8}\ s=1.2\times 10^{-8}\ \times 10^9\\\\=1.2\times 10\\\\=12\ ns[/tex]

So, there are 12 nanoseconds in [tex]1.2\times 10^{-8}\ s[/tex].

Lithium arsenate (Li3AsO4) and iron nitrate (Fe(NO3)3) are dissolved in water. What precipitate would you expect to form? Write the name and formula. (use the solubility table to help)

Answers

Salts with nitrates as the anion are generally soluble in water. The question isn’t quite clear: Are we being asked what precipitate would form if these solutions were mixed together? If that’s the case, the reaction would be as follows:

Li3AsO4(aq)+ Fe(NO3)3(aq) → 3LiNO3(aq) + FeAsO4(s).

It is odd that we’re given lithium arsenate dissolved in water to begin with as lithium arsenate should be insoluble. But assuming that it is water-soluble, we can obtain the net ionic equation for the formation of our precipitate:

Fe3+(aq) + [AsO4]3-(aq) → FeAsO4(s).

Our precipitate would be iron(iii) arsenate, FeAsO4.

Write balanced equations for all the reactions in the catabolism of glucose to two molecules of glyceraldehyde 3-phosphate (the preparatory phase of glycolysis), including the standard free-energy change for each reaction. Then write the overall or net equation for the preparatory phase of glycolysis, with the net standard free-energy change.

Answers

Solution :

The balanced chemical equation are

The Catabolism of the glucose takes place in five stages :

1. Glucose + [tex]$ATP$[/tex] → glucose - [tex]$6$[/tex] - phosphate [tex]$+ ADP$[/tex]  ,  [tex]$\Delta G^0=-16.7 \ kJ/mol$[/tex]

2. Glucose - [tex]$6$[/tex] - phosphate → Fructose - [tex]$6$[/tex] - phosphate ,  [tex]$\Delta G^0=1.7 \ kJ/mol$[/tex]

3. Glucose - [tex]$6$[/tex] - phosphate + [tex]$ATP$[/tex] → [tex]$ADP$[/tex] + Fructose - [tex]$1,6- \text{biophosphate}$[/tex],  [tex]$\Delta G^0=-14.2 \ kJ/mol$[/tex]

4. Fructose - [tex]$1,6- \text{biophosphate}$[/tex]  → dihydroxyacetonephosphate + glyceraldehyde  [tex]$-3 - $[/tex] phosphate,   [tex]$\Delta G^0=23.8 \ kJ/mol$[/tex]

5. Dihydroxyacetonephosphate → glyceraldehyde  [tex]$-3 - $[/tex] phosphate , [tex]$\Delta G^0=7.5 \ kJ/mol$[/tex]

Therefore, the overall net equations

Glucose + [tex]$2ATP \rightarrow$[/tex] glyceraldehyde  [tex]$-3 - $[/tex] phosphate + [tex]$2ADP$[/tex] [tex]$\Delta G^0=2.1 \ kJ/mol$[/tex]

Did entropy increase or decrease?
1) 2 SO3 (g) → 2 SO2 (g)+O2 (g)
2) MgCO3 (s) + 2 H3O^+ (aq) → Mg^2+ (aq) + 3 H2 O(I) + CO2 (g)

Answers

Answer:

1) increase

2) increase

Explanation:

Entropy is the degree of disorderliness or randomness of a system. It is the measure of the unavailable energy in a system.

Entropy increases with increase in the number of particles. If the number of particles in a system increases from left to right, the entropy of the system increases accordingly.

In reaction 1, the number of particles from left to right increased from two to three hence the entropy was increased.

In reaction 2, the number of particles from left to right increased from three to five hence the entropy was increased.

A sample of aluminum foil contains 9.20 x 1023 atoms. What is the mass of the foil?​

Answers

A sample of aluminum foil contains 9.20 x 1023 atoms, then mass of foil will be 41.24 gram.

Aluminum foil serves as a barrier to air and oxygen, which could heat up food that is cold or frozen. In the end, it is beneficial since it keeps the food's temperature, irrespective of whether it's warm or cold.

Iron and silicon make up the majority of the remaining 2.5% of aluminum foil, which gives it strength as well as puncture resistance. Between big, water-cooled chilling rollers, the molten alloy has been rolled thin as well as solidified. Two layers of foil were run through the mill simultaneously even during final rolling.

It is known that 1 mol = 6.022 × [tex]10^{23}[/tex]

and, 1 mol of aluminum = 27 g.

It is given that, count of Al atoms = 9.20 × [tex]10^{23}[/tex]

So,  9.20 × [tex]10^{23}[/tex] particle has mass = 27 /  6.022 × [tex]10^{23}[/tex]  ×  9.20 × [tex]10^{23}[/tex]

Which will be equal to 41.24gram.

Therefore, the mass of foil will be 41.24 gram.

Yes, Pb3(PO4)2.

Explanation:

Hello there!

In this case, according to the given balanced chemical reaction, it is possible to use the attached solubility series, it is possible to see that NaNO3 is soluble for the Na^+ and NO3^- ions intercept but insoluble for the Pb^3+ and PO4^2- when intercepting these two. In such a way, we infer that such reaction forms a precipitate of Pb3(PO4)2, lead (II) phosphate.

7. Convection

8. Radiation

9. Conduction

Explanation:

Convection is when a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along.

Radiation is the energy that is emitted by matter in the form of photons or electromagnetic waves. So, it is coming off the fire which makes it radiation.

Conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. Because the picture shows different temperatures, it leds to the conclusion that 9 is conduction.

The equation H2 + O2 -> H2O is unbalanced. When balanced, what is the correct coefficient for O2?

Answers

Answer:

The balanced equation would be 2H2 + O2 -> 2H2O

Explanation:

The correct balanced equation is 2H₂ + O₂  →  2H₂O, and  the correct coefficient for O₂ is 1.

How to balance a chemical equation?

Count the atoms on each side first. Next, alter one of the compounds' coefficient. Third, count the atoms once more, and then repeat steps two and three until the equation is balanced.

In the given equation, hydrogens are already balanced. To balance oxygen, multiple water with 2. Thus, equation becomes:

H₂  + O₂  →  2 H₂O

Now, oxygen is balanced, just the hydrogens got unbalanced. To balance hydrogen, multiply the hydrogen by 2 on the left side.

2 H₂ + O₂  → 2H₂O

Now the chemical equation is balanced, in which the number of oxygen and hydrogen are equal on both sides of the arrow.

Therefore, the coefficient of O₂ is 1.

Meteoroids are small rocky or metallic objects that are in space and can potentially enter the Earth's atmosphere. By determining if the object is made of rock, it aligns with the characteristics of a meteoroid.

Option A, "Was the object once part of an asteroid?" does not necessarily confirm that the object is a meteoroid since meteoroids can come from various sources, not just asteroids.

Option B, "Where is the object located?" does not provide specific information about the nature of the object and can apply to comets and asteroids as well.
