Lithium reacts with hydrochloric acid to give lithium chloride and hydrogen gas.
What is the balanced symbol equation for this reaction?
Li+HCl→LiCl+H\text{Li} + \text{HCl} \rightarrow \text{LiCl} + \text{H}Li+HCl→LiCl+H
Li+HCl→LiCl+H2\text{Li} + \text{HCl} \rightarrow \text{LiCl} + \text{H}_2Li+HCl→LiCl+H2
2Li+2HCl→2LiCl+H22\text{Li} + 2\text{HCl} \rightarrow 2\text{LiCl} + \text{H}_22Li+2HCl→2LiCl+H2
2Li+2HCl→2LiCl+2H2\text{Li} + 2\text{HCl} \rightarrow 2\text{LiCl} + 2\text{H}2Li+2HCl→2LiCl+2H
