Answer:

Several properties (listed in the explanation)

Explanation:

The volume and density of air change with changes in temperature, T.

There are several things that take place:

As the temperature of air increases:

1. the volume increases - The gas particles have more kinetic energy to move hence the increase in volume. The kinetic energy is directly related to temperature as the energy is derived from the energies of the particles

2. the density decreases- there is less mass of air per unit volume. The air particles are not closely bound together

As the temperature of air decreases:

1. The volume decreases - the air particles lose kinetic energy and are close together.

2. the density increases - there is more weight per unit volume due to lower kinetic energy.

Answer: Boyle's Law

-----

Boyle's Law is the pressure-volume law and it relates pressure and volume at constant temperature. Boyle's law states that pressure and volume vary inversely, meaning that as one goes up, the other one goes down.

Answer:

1. Hydrogen Iodide

2. 6 molecules of Hydrogen Iodide

3. Iodine is the limiting reagent

Explanation:

The image of the illustration in the question has been attached:

1. The illustration represents a mixture of hydrogen ( light blue ) and iodine ( purple )

H₂ + I₂ ---> 2HI

This forms hydrogen iodide.

2. In the given illustration, 6 product molecules of Hydrogen Iodide. This is indicated in the box on the right side of the illustration.

3. The limiting reagent is the reactant that determines how much of the products are made. It is the substance that is totally consumed when the chemical reaction is completed. In the box on the right side of the illustration, you will see that hydrogen which is indicated by blue is in excess. The limiting reagent is the one that is completely consumed which is the iodine.
