Answer 1

Answer:

1 Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s). 1. Take two iron nails and clean them with a sand paper.

2 Sulphur dioxide is an acidic gas and this can easily be demonstrated by adding water and a few drops of universal indicator to a container of the gas. The resulting acid is the weakly dibasic acid sulphurous acid (H2SO3).
