Answer: The correct answer is true.
Explanation:
There are two types of reactions based on the heat absorbed or released:
1. Exothermic reactions: In these reactions, heat is released. The energy of the products is less than the energy of the reactants. The for these reactions is negative.
2. Endothermic reactions: In these reactions, heat is absorbed by the reactants. The energy of the products is more than the energy of the reactants. The for these reactions is positive.
In the given equation:
The energy is written on the product side, which means that the heat is released in the reaction. Hence, the given equation is a exothermic reaction.
Therefore, the given statement is true.

B. Rock Y cooled more slowly than rock X.
Explanation:
Igneous rocks are rocks that forms from the solidification of magma either on the earth surface or beneath surface.
Those that forms on the surface are called volcanic rocks
Those that forms beneath are called plutonic rocks.
When magma forms within the surface, it cools and solidifies slowly. This will allow crystals to grow slowly. Therefore, the crystals will have a big size in the rock. The texture of the rock is now said to be coarse grained.
Those that forms on the surface cool rapidly and the minerals are fine grained. This is the case with X
