Write complete balanced equations for the following reactions:(a) Calcium (solid) + Water (liquid) ------> Calcium hydroxide (solution) + Hydrogen (gas)(b) Sulphur dioxide (gas) + Oxygen (gas) ------> Sulphur trioxide (gas)
The complete balanced equations for the reactions are given below:
(a) Calcium (solid) + Water (liquid) → Calcium hydroxide (solution) + Hydrogen (gas)
$Ca\ ( s) \ +\ 2H_{2} O\ ( l) \ \rightarrow \ Ca( OH)_{2} \ ( aq) \ +\ H_{2} \ ( g)$
(b) Sulphur dioxide (gas) + Oxygen (gas) → Sulphur trioxide (gas)
$2SO_{2} \ ( g) \ +\ O_{2\ }( g) \ \rightarrow \ 2SO_{3} \ ( g)$
