(a)
Interpretation:
Whether calcium chloride is an element, compound or a mixture is to be explained.
Concept introduction:
An element can be defined as the simplest type of matter which is composed of only one kind of atom and cannot be broken down further. The properties of all the atoms of an element are identical.
A compound is defined as a substance formed by the combination of two or more different elements in a fixed proportion via a
