Question

balanced chemical equations can give us the mol ratios between reactants needed, but do not give any information about ratios between reactants and products.

1. true
2. false

Explanation:

A balanced chemical equation shows the mole ratios between all reactants and products (as well as between reactants). For example, in $\ce{2H_2 + O_2 -> 2H_2O}$, the mole ratio of $\ce{H_2}$ to $\ce{O_2}$ (reactants) is 2:1, and the ratio of $\ce{H_2}$ (reactant) to $\ce{H_2O}$ (product) is 2:2 (or 1:1), and $\ce{O_2}$ to $\ce{H_2O}$ is 1:2. So the statement is false.

Answer:

1. False
