Answer 1

1)delS<0 because there there is solid in product side and solid have less entropy.

2}delS>0 because product side have aqueous and liquid which have more entropy than the solid which are present on reactant side

3} delS>0 because there are 7 molecule of gas in product side than the 4 on reactant hence entropy increases.
