Question

write the valency of cl,o,n,so4 and no3 in the following: hcl h2o nh3 h2so4 hno3

Answer 1

Answer:

HCL = H+ + Cl-

Valency of Cl = -1

H2O = 2H+ + O 2-

Valency of O = -2

NH3 = N 3- + 3H+

Valency of N = -3

SO4 2- = S 6+ + 4O 2- (6+4(-2) = -2)

Valency of S = +6

NO3 - = N 5+ 3O 2- (5+3(-2)= -1)

Valency of N = +5

Hope you understood, if yes, then plz don't forget to mark my answer as the brainliest.
