(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
A mixture consists of a combination of two or more compounds or elements or compound and an element which are physically intermingled.
(b)
Interpretation:
Whether the octatomic molecule of sulfur 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 chemical reaction. The property of a compound is different from the properties of the constituent elements.
A mixture consists of a combination of two or more compounds or elements or compound and an element which are physically intermingled.
