Which equation represents a neutralization reaction?
O 2H2 + O2 → 2H20
o 2H202 → 2H2O + O2
HCI + KOH → KCI + H20

HCI + KOH → KCI + H20

Explanation:

HCI(aq) + KOH(aq) → KCI(aq) + H20(l)

Acid + base → Salt + Water.

The above is a neutralization reaction in which an acid, aqeous HCl reacts completely with an appropriate amount of a base, aqueous KOH to produce salt, aqueous KCl and water, liquid H2O only.

This is a neutralization reaction since, the hydrogen ion, H+, from the HCl is neutralized by the hydroxide ion, OH-, from the KOH to form the water molecule, H2O and salt, KCl only.

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.
