Question

the formula of nitride of a metal X is XN,state the formula of :1) its sulphate 2) its hydroxide.

Answer 1

we know that nitride ion has -3 charge since the formula is XN then charge on X should be +3 ,
Sulphate is X2(SO4)3 (charge on sulphate ion is -2)
Hydroxide is X(OH)3 (charge on hydroxide is -1)

Answer 2

Answer:

Formula - XN

as val of N is 3. so X's val is 3

so formula of its sulphate X2(SO4)3

so formula of its hydroxide X(OH)3

Hope it helps!!
