Which equation represents neutralization?
(1 ) 6Li(s)+N 2 (g)=>2Li3N(s)(2) 2Mg(s)+O2(g)=>2MgO(s) (3) 2KOH(aq)+H2SO4(aq) =>K 2 SO 4 (aq)+2H 2 O(l)
(4) Pb(NO 3 ) 2 (aq)+K 2 CrO 4 (aq) => 2KNO 3 (aq)+PbCrO 4 (s)

Respuesta :

Answer:

3) 2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)

Explanation:

KOH is a strong base and a H2SO4 is a strong acid. The two react in a neutralization reaction, producing a salt and water.
