Fofino [41]

Answer:

a) 2ZnS(s)+3O_2(g)\rightarrow 2ZnO(s)+2SO_2(g)

2 moles of Zinc sulphide in solid form reacts with 3 moles of Oxygen in gaseous form to give 2 moles of Zinc oxide in solid form and 2 moles of sulphur dioxide in gaseous form.

b)  CaH_2(s)+2H_2O(l)\rightarrow Ca(OH)_2 aq)+2H_2(g)

1 mole of calcium hydride in solid form reacts with 2 moles of liquid water to give 1 mole of calcium hydroxide dissolved in water and 2 moles of hydrogen in gaseous form.

The chemical reactions are written by writing the chemical formula of the reactants on left side of the arrow followed by chemical formula of the products. The number of atoms of each element must be balanced to follow the law of conservation of mass.
