Question

I want question no 32
33
And
34 also plss urgent I need it plsss

Answer 1

33-Potassium nitrate
--hydrochloric acid
--calcium chloride
-- calcium carbonate
Valency of X -- 4
--electronic conifiguration --2,8,4

Answer 2

Question No.32

56g of Na atoms

Number of fundamental particles = No.of moles * 6.022*10^23

--> No.of moles = Given mass/Atomic Mass

--> No.of moles = 56/23 = 2.44

Therefore, Number of particles of Na

= 2.44*6.022*10^23

=14.4*10^23 (Ans)

Question No.33

Pretty Direct;

a].KNO3 -->> Potassium Nitrate

b]HCl -->> Hydrogen Chloride

C] CaCl2 --> Calcium Chloride

D] CaCO3 --> Calcium Carbonate

Question 34.

No.of protons and Electrons are 14

Valency is 4

Electronic config.

2,8,4

or

1s2 2s2 2s2 2p6 3s2
