Question

7. The reaction :
Calcium hydroxide + Nitric acid → Calcium nitrate + Water
What kind of reaction is this?
a. Neutralisation reaction
b. Exothermic reaction
C. Double decomposition reaction
d. All of these​

Answer 1

Answer:

A. Neutralization Reaction.

Explanation:

Acid + Base = Neutral

Answer 2

Answer:

a

Explanation:

because (2 HNO3 + Ca(OH)2 --> Ca(NO3)2 + 2 H2O

If you understand how the neutralization works, you don't have to memorize it. The two hydroxides(OH-) from calcium hydroxide, which need two H+ ( hence the 2:1 ratio with HNO3) produce 2 H2O. Meanwhile you need a pair NO3- to balance the +2 charge of calcium, which is why it generates Ca(NO3)2.
