Answer is: B.) A solid gains kinetic energy to become a liquid and then becomes a gas.

Stage 2 is melting (from solid to liquid) and Stage 2 is boiling (from liquid to gas).

In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object does not take on the shape of its container.

Liquids have definite volume, but no fixed shape.

Gases not have definite volume and fixed shape, it depends on its container.

Answer:

reactants: 2 O2

products: 3 CO2, 4 NO2, 6 H2O

Explanation:

In a combustion, a combustible material, which generally is composed of C, H, O, N, and S, is combusted, that is, react with oxygen after a spark was produced; obtaining fire, heat and subproducts, including ashes and gases.

Oxygen is always one of the reactants of a combustion.

If Nitrogen was present in the combustible, NO2 (or other nitrogen oxides) will be produced.

If Carbon was present in the combustible, CO2 will be produced (also CO can be produced).

If Hydrogen was present in the combustible, H2O will be produced.
