Hydrobromic acid, HBr\text{HBr}HBr, reacts with barium metal, Ba\text{Ba}Ba.
Barium bromide and hydrogen gas are formed.
What is the balanced symbol equation for this reaction?
2HBr+Ba→BaBr+H22\text{HBr} + \text{Ba} \rightarrow \text{BaBr} + \text{H}_22HBr+Ba→BaBr+H2
2HBr+Ba→BaBr2+H22\text{HBr} + \text{Ba} \rightarrow \text{BaBr}_2 + \text{H}_22HBr+Ba→BaBr2+H2
HBr+Ba→BaBr2+H2\text{HBr} + \text{Ba} \rightarrow \text{BaBr}_2 + \text{H}_2HBr+Ba→BaBr2+H2
2HBr+Ba→BaBr2+H2\text{HBr} + \text{Ba} \rightarrow \text{BaBr}_2 + \text{H}2HBr+Ba→BaBr2+H
