Explanation:

and leave me a good review

1) increases

2)increases

3) Decreases

4) increases

5) increase

6) decreases

Explanation:

Let us remember that in a solid, the molecules of the substance are trapped in fixed positions hence the entropy of a solid is less than that of liquid as well as less than the entropy of a gas.

Reaction (1) and (2) deal with a change of state from solid to liquid or gas leading to increase in entropy.

In reaction (3) the aqueous reactants convert into a liquid product leading to a decreases in entropy.

Reaction (4) and (5) has to do with change of a solid to a gas as well as an increase in volume leading to an increase in temperature.

For reaction(6), a solid is formed so entropy decreases
