Because the kiln utilizes fire, fire uses oxygen and the fuel to create CO2
CO2 would be the main gas because the main components of the reactants are carbon and oxygen, which make up CO2
The correct answer is D. Using the law of conservation of mass the number of atoms on each side of the equation should be equal. Through introspection, we find that there are 2
atoms on reactant side as opposed 3Cl atoms on product side. If we add a coefficient of 3 on 
we get
.
Now there are 6Cl atoms on reactant side and 2 on product side, hence we add a coefficient of 2 on both 
and 
. The balanced chemical equation is,
Answer:
A catalyst is a substance which increases the rate of a chemical reaction without itself getting consumed. It is known that all catalysts are enzymes but all enzymes are not catalysts.
Explanation:
