Answer:
The wax
Explanation:
The limiting reactant is the reactant in short supply in a particular reaction. This reactant determines the extent of the reaction. Oxygen in the reaction is the one in excess. As we know that oxygen is free in the atmosphere and it is in excess supply.
After the wax finishes burning the reaction stops and no more production of carbon dioxide, water and energy but oxygen still continues to abound all around.
In order to determine the amount of carbon dioxide and water that would be produce, we simply use the amount of wax to relate with them.
The density does not affect the earth's interior, the affection of pressure on the earths layers raises the temperature therefore making it have an effect on the layers.
