Question:

When heated, {eq}KClO_3 {/eq} decomposes into {eq}KCl {/eq} and {eq}O_2 {/eq}.

{eq}2KClO_3 \rightarrow 2KCl + 3O_2 {/eq}

If this reaction produced 23.7 g of {eq}KCl {/eq}, how many grams of {eq}O_2 {/eq} were produced?

Balanced Chemical Equations:

Balanced chemical equations model the interactions between the chemicals that are allowed to react. This also considers the mass conservation, wherein appropriate coefficients are included in the expression in order to keep the equality between the number of atoms per element on each side of the equation.
