Question

The metals x y and z have valencies of 1 2 3 respectively write the formula of their sulphate carbonates and nitrate metals x y and z have valencies of 1 2 3 respectively write the formula of their sulphate carbonates and nitrate?

Answer 1

Answer:

please make me brainliest

Explanation:

Oxygen

Element X is Na.Its oxide is Na

2

O and mass will be = 23 + 23 + 16 = 62

Element Y is Al and oxide is Al

2

O

3

and mass will be 27+ 27 + {16*3} = 102.

Element Z is sulphur and oxide is SO

2

and mass = 32 + {2*16} = 64

Difference in atomic mass of X and Y = 4.

32/4 = 8 = Oxygen's atomic no.
