Answer:

X represents London dispersion forces, and Y represents ion-dipole forces.

Explanation:

London forces occurs between molecules that are normally non-polar (electrically symmetric). It arises from instantaneous dipoles in molecules. It occurs in all substances.

Permanent dipoles are caused by non-symmetric electron distribution in molecules leading to a permanent dipole in the molecule such as in HCl. Interaction between the permanent dipole in these molecules and an ion is called ion-dipole interaction.

Hence; X represents London dispersion forces, and Y represents ion-dipole forces.

Definition:

Molarity of a given solution is defined as the total number of moles of solute per litre of solution. The molality of a solution is dependent on the changes in physical properties of the system such as pressure and temperature as unlike mass, the volume of the system changes with the change in physical conditions of the system. Molarity is represented by M, which is termed as molar. One molar is the molarity of a solution where one gram of solute is dissolved in a litre of solution. As we know, in a solution, the solvent and solute blend to form a solution, hence, the total volume of the solution is taken.

Formula :

[tex]m \: = \frac{n}{v} [/tex]

Where,

m = molar concentration

n = moles of solute

v = litres of solution.

95.8% is the percent yield for sodium chloride if 56.0 g of sodium chloride is produced in the reaction.

Percentage yield of any chemical reaction can be calculated as:

% yield = (Experimental yield/Theoretical yield) × 100

Given chemical reaction is:

NaHCO₃ + HCl → NaCl + CO₂ + H₂O

In the question it is given that 56 grams of NaCl is produced by mass. But according to the stoichiometry of the reaction 1 mole of NaCl will be produced whose mass should be 58.44 grams. So, % yield will be:

% yield = (56/58.44) × 100 = 95.8%

Hence, option (d) is correct it means 95.8% is the percent yield.

The pool float looked would have looked deflated the next morning.

Explanation:

When temperature decreases the volume decreases

Answer:

The pool float most likely looked a little deflated or pushed in

Explanation:

The pool float most likely looked a little deflated or pushed in. This is because during the night temperatures most likely dropped. These cold temperatures during the night would have caused the air molecules inside the pool float to come closer together which would cause there to be more excess space inside the pool float. Therefore, allowing it to collapse into itself. This would be far worse if the float was filled with helium or another gas other than O2.

Answer:

[tex]a=-3.37\ m/s^2[/tex]

Explanation:

Given that,

A car accelerates negatively from 35m/s to 8m/s in 8s.

We need to find the car's acceleration.

Initial speed, u = 35 m/s

Final speed, v = 8 m/s

Time, t = 8 s

The acceleration of an object is equal to the rate of change of velocity. So,

[tex]a=\dfrac{v-u}{t}[/tex]

Put all the values,

[tex]a=\dfrac{8-35}{8}\\\\a=-3.37\ m/s^2[/tex]

So, the acceleration of the car is equal to [tex]-3.37\ m/s^2[/tex].

22.45g of Fe will be produced

Explanation:

The balanced reaction is:

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)

Where 1 mole of Iron (III) oxide reacts with 2 moles of Iron

To solve this question we have to find the moles of iron (III) oxide. With these moles and the balanced reaction we can find the moles of iron produced and its mass:

Moles iron (III) oxide -Molar mass: 159.69g/mol-

32.1g Fe₂O₃ * (1mol / 159.69g) = 0.201 moles Fe₂O₃

Moles Iron:

0.201 moles Fe₂O₃ * (2mol Fe / 1mol Fe₂O₃) = 0.402 moles of Fe

Mass Fe -Molar mass: 55.845g/mol-

0.402 moles of Fe * (55.845g/mol) =

Answer: When we eat the food gets digested.

Explanation: Once filled with food, the stomach grinds and churns the food to break it down into small particles. It then pushes the small particles of food into the first part of the small intestine, called the duodenum. The small intestine is where most of the digestion and absorption of our food takes place.

is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.

It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas

for heating, cooking, and electricity generation. It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.

When methane undergoes combustion the carbon dioxide (CO₂) and water (H₂O) is formed. Therefore, option C is correct.

A chemical reaction between two or more substances, usually involving oxygen, that produces heat and light in the form of a flame is called as combustion. The reaction is as follows:

CH4(g) + 2O₂(g) → CO₂(g) + 2H₂O

Methane burns in the presence of enough oxygen to produce carbon dioxide (CO₂) and water (H₂O). When it is burned, it produces a large amount of heat, making it an excellent fuel source.

Thus, option C is correct.

Answer:

[tex]Cu_{3}P[/tex]

Explanation:

usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step

least molar ratio:

Cu =  [tex]\frac{1.5}{0.5}[/tex] = 3

P = [tex]\frac{0.5}{0.5}[/tex] = 1

thus, empirical formula = [tex]Cu_{3}P[/tex]

The empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus is Cu₃P.

Empirical formula of any compound gives idea about the number of constituents particles present in that compound by mentioning the ration.

In the question, given that:

Moles of copper = 1.5 moles

Moles of phophorous = 0.5 moles

Now we divide the given moles by the smallest number to get the ration number as follow:
Cu  :  P

1.5/0.5  :  0.5/0.5

3  :  1

Hence, required empirical formula is Cu₃P.

A thermite reaction releases large amounts of heat and light, resulting in the melting of the iron metal that forms during the reaction. The balanced chemical equation is given below: Fe₂O₃(s) + 2Al(s) ---> Al₂O₃(s) + 2Fe(l) Determine the correct mole ratios for the following substances, based on this chemical equation.

Explanation:

A thermite reaction is a highly exothermic reaction that occurs between a mixture of powdered aluminium and iron (iii) oxide.

The reaction is a redox reaction which produces aluminium oxide and metallic iron.

The heat given out in the reaction melts the iron formed. It is used to join railway tracks or cracked machine parts. The molten iron runs down between the tracks and welds them together.

The balanced equation of the reaction is given below :

Fe₂O₃(s) + 2Al(s) ---> Al₂O₃(s) + 2Fe(l) + Heat

The mole ratio of the reactant and products are as follows:

1. 1 mole of Iron (iii) oxide and 2 moles of aluminium are combined

Fe₂O₃ : Al = 1 : 2

2. 1 mole of aluminium oxide is produced from 1 mole of iron (iii) oxide

Fe₂O₃ : Al₂O₃ = 1 : 1

3. 2 moles of of iron are produced from 1 mole of iron (iii) oxide
