Answer 2

Norrie said what I was going to. I think that's right.

Answer 3

Johnny was a chemist,

But Johnny is no more.

What Johnny thought was H2O

Was (NH4)2SO4.

Nah... doesn't flow right.

Answer 4

N = 2, H = 8, S = 1 and O = 4 = 15 atoms in the molecule.

(NH4)2 ..the '2' is a subscript indicating that everything in the brackets is times 2.

((2 x N); + (2 x 4H); + (1 x S); + (4 x O) = 15 total).
