Which equation represents neutralization? 6Li(s) + N2(g) → 2Li3N(S)
2Mg(s) + O2(g) → 2MgO(S)
2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)
Pb(NO3)2(aq) + K2CrO4(aq) → 2KNO3(aq) PbCrO4(s)

2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)

Explanation:

A neutralization reaction refers to any reaction between an acid and a base to form salt and water only. In a neutralization reaction, the key reaction that takes place to produce water is shown ionically below;

H^+(aq) +OH^-(aq) > H2O(l)

Looking at all the options provided, our gaze will have to settle on the reaction;

2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)

We can clearly see that there is an acid that reacts with a base to form a salt and water. The base contains the OH^- ion while the acid contains the hydrogen ion.

This is the only reaction of this sort among the options hence it is the correct answer.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
