<span>First we write the reactants and the products in this manner shown below:
C5H12 + O2 = H20 + CO2
This equation is not yet balanced so we add coefficients to make the equation balance:
</span><span>C5H12 + 8O2 = 6H20 + 5CO2
</span>
The principle of concern here is the Law of Conservation of Mass.
<span>This law states that for a system that is isolated, the mass is not created nor destroyed. Hence for this system, the amount of CO2 and water created is exactly from the reactants pentane and oxygen.

By the information you gave i can say that when atoms gain energy the molecules spread out and if you had a solid it would become a liquid and if you had a liquid it would become a gas
Hope this helps
The kinetic model theory states that the particles of gases behave as perfectly elastic spheres, exhibiting elastic collisions, where kinetic energy is conserved, whenever they hit something.

Answer:
Identify each equation as a composition reaction, a decomposition reaction, or neither.
Fe2O3 + 3 SO3 → Fe2(SO4)3
NaCl + AgNO3 → AgCl + NaNO3
(NH4)2Cr2O7 → Cr2O3 + 4 H2O + N2
Solution
In this equation, two substances combine to make a single substance. This is a composition reaction.
Two different substances react to make two new substances. This does not fit the definition of either a composition reaction or a decomposition reaction, so it is neither. In fact, you may recognize this as a double-replacement reaction.
A single substance reacts to make multiple substances. This is a decomposition reaction.
Test Yourself
Identify the equation as a composition reaction, a decomposition reaction, or neither.
C3H8 → C3H4 + 2 H2
