Ammonium Sulphate - (NH4)2 SO4

Answer 2

$\huge {\bold {\red {ELEMENTS....}}}$

$\bold {{Water \:( H2O) }}$
= hydrogen; H and oxygen; O

$\bold {{Copper\: nitrate \: (CuNO3)}}$
= copper; Cu, Nitrogen ; N and oxygen; O

$\bold {{Sodium \: nitrate \: (NaNO3)}}$
= Sodium ; Na, Nitrogen ; N and oxygen ; O

$\bold {{Ammonium \: Sulphate \: (NH4SO4)}}$
= Nitrogen ; N, Hydrogen ; H, Sulphur; S and Oxygen ; O
