Question

balance the chemical reaction below.
hbr + ba(oh)₂ → babr₂ + h₂o
what is the coefficient for hydrobromic acid (hbr) when the reaction is balanced?
hint: h₂o is the same as h - oh.

Explanation:

Step1: Balance bromine atoms

On the right - hand side, there are 2 bromine atoms in \(BaBr_2\). So, we put a coefficient of 2 in front of \(HBr\) on the left - hand side. The equation becomes \(2HBr+Ba(OH)_2
ightarrow BaBr_2 + H_2O\).

Step2: Balance hydrogen and oxygen atoms

After putting a coefficient of 2 in front of \(HBr\), on the left - hand side, we have \(2H\) from \(HBr\) and \(2H\) and \(2O\) from \(Ba(OH)_2\). On the right - hand side, we have \(2H\) and \(1O\) in \(H_2O\). If we put a coefficient of 2 in front of \(H_2O\), the equation \(2HBr + Ba(OH)_2=BaBr_2+2H_2O\) is balanced.
