Question

find the chemical formula of ammonium chloride and sodium sulphate using criss-cross method​

Answer 1

Chemical formula: (NH

4

)

2

SO

4

Answer 2

Answer:

Explanation:

valency of NH4 = 1

valency of Cl = 1

molecular formula for ammonium chloride by criss cross method :

NH4 - CL

=1 - 1

=0

Therefore, by criss cross method, we get the molecular formula of ammonium chloride.

I.e. NH4Cl
