Question

the formula of the nitride of a metal X is XN, state the formula of its sulphate and ots hydroxide?

Answer 1

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!!

Answer 2

The formula of sulphate and hydroxide is X2SO43 and XOH3.

• The formula for Nitride ion is -3. Now, as the 1 ion of X binds with the ion, its formula should be +3.
• As per the known information, the formula of sulphate ion is -2 and the formula of hydroxide ion is -1.
• So, 2 ions of element X will bind with 3 sulphate ions to form a stable compound.
• With 3 hydroxyl ions, 1 ion of X will bind to form a stable compound.
• Hence, the formula of sulphate and hydroxide of X is X2SO43 and XOH3.
