Which equation represents a neutralization reaction? a. 4fe(s) + 3o2(g) → 2fe2o3(s) b. 2h2(g) + o2(g) → 2h2o() c. hno3(aq) + koh(aq) → kno3(aq) + h2o() d. agno3(aq) + kcl(aq) → kno3(aq) + agcl(s)

The equation represents a neutralization reaction is HNO3(aq) + KOH(aq) → KNO3(aq) + H2O(). The answer is letter C. A. 4Fe(s) + 3O2(g) → 2Fe2O3(s), 2H2(g) + O2(g) → 2H2O() and AgNO3(aq) + KCl(aq) → KNO3(aq) + AgCl(s) are not neutralization reaction.
