C. two billiard balls colliding and bouncing off each other
Explanation:
From the given options, the most similar scenario to the type of collision depicted in the kinetic molecular theory is the collision of the two billiard balls bouncing off each other.
Here are some of the postulates of the kinetic molecular theory:
- A gas is composed of a large number of identical molecules moving at different speeds.
- The space occupied by the gas molecules is negligible compared to the volume of the container.
- Molecules move independently of one another
- Molecules collides with one another and with the walls of the container elastically i.e without loss of kinetic energy.
- The temperature of the gas is a measure of its average kinetic energy.

Answer:
4.8x10⁻³ Liters are required
Explanation:
Molarity is an unit of concentration in chemistry defined as the ratio between moles of solute (In this case, silver nitrate) and liters of solution.
The 0.50M solution contains 0.50 moles of silver nitrate per liter of solution.
To provide 2.4x10⁻³ moles Silver nitrate are required:
2.4x10⁻³ moles * (1L / 0.50 moles) =
<h3>4.8x10⁻³ Liters are required</h3>
<span>Answer: option 3) magnesioum reacts with an acid.
</span><span />
<span>Justification:
</span><span />
<span>1) Malleability, conduction of electricity, and boiling point are physical properties.
</span><span />
<span>2) Maleability is the ability to be transformed into foil. It is just a change in form. So, it is a physical property.
</span><span />
<span>3) The metals conduct electricity in virtue of the array of the atoms, which permtis the flow of the electrons, but it does not involve a chemical change, so it remains being a physical proerty.
</span><span />
<span>4) Boling point is the temperature at which a substance passes from liquid state to gas state, which are just different forms of the same substance. So, it is other physical property.
</span><span />
<span>5) Reaction with an acid is indeed a chemical transformation: the metal (magnessium) will form a chemical bond with some spieces of the acid to form a new compound. This is a chemical reaction in virtue of the chemcial properties of the substance (its ability to react with acids)</span>
Answer:
Single replacement is a reaction in which one element reacts with another compund to form another compound and another element.
