Question

solid calcium is taken in a container and water is added slowely to it. 1)write your observations. 2)write the chemical formula of the product found. 3)mention the type of reaction involved​

Answer 1

Answer:

Two observations made in the experiment are:-

(a) Temperature is raised due to the vigorous reaction.

(b) It is an exothermic reaction, heat is observed.

(ii)

quicklime

CaO

(s)+

water

H

2

O

(l)⟶

CalciumHydroxide

Ca(OH)

2

+Δ(heat)

∴ Calcium Hydroxide is produced

Answer 2

Answer:

1. when calcium is added to water heat is released out. and it  reacts with water and produces calcium hydroxide which is a precipitate , and hydrogen gas.

2. Ca(OH)2 which is calcium hydroxide

3. the type of reaction is displacement reaction and exothermic reaction and even it is a precipitation reaction
