Answer & Solution
Correct Answer
(A) \(2 \mathrm{H}_2 \mathrm{O}_{2(\ell)} \rightarrow 2 \mathrm{H}_2 \mathrm{O}_{(\ell)}+\mathrm{O}_{2(\mathrm{~g})}\)
Step-by-step Solution
Detailed explanation
\(\Delta n_g = (\text{moles of gaseous products}) - (\text{moles of gaseous reactants})\) For \(2 \mathrm{H}_2 \mathrm{O}_{2(\ell)} \rightarrow 2 \mathrm{H}_2 \mathrm{O}_{(\ell)}+\mathrm{O}_{2(\mathrm{~g})}\):
