Answer:
(C) Decomposition reaction
Explanation:
A decomposition reaction is a chemical reaction in which a single compound breaks down into two or more compounds or elements.
<u>in this example </u>
- 2KClO₃(s) ->2KCl (s) + 3O₂ (g)
Potassium chlorate (KClO₃) decomposed to two smaller compounds KCl and O₂ gas.
So, the right choice is (C) Decomposition reaction
Answer:
the volume will decrease
Explanation:
an increase in temperature will lead to an increase in effective collision which also result in an increase in volume, when the temperature decreases, the volume will decrease

Explanation:
A plastic polymer material that becomes soft upon heating and hard once again when cooled such that the material can be repeatedly or cyclically cooled and heated numerous times with its chemical and physical properties remaining constant is known as a thermoplastic.
A plastic, polymer or resin that is hardened from its soft or liquid state by curing irreversibly such that it cannot be made soft again without a change in its chemical properties is known as a thermosetting plastic.
D. It slows down
It slows down because the water keeps its from sinking
