Concept explainers
Interpretation:
Whether the species involved in the reaction represent elements, compounds or mixtures is to be determined.
Concept introduction:
An element can be defined as the simplest type of matter which is composed of only one kind of atom. Hence elements can be represented by symbols. Elements cannot be broken down into simpler substances by any chemical or physical means. Examples are carbon, hydrogen, oxygen, sulfur, chlorine, etc.
Compounds are formed by the combination of two or more different elements in a fixed ratio. Compounds are represented by using chemical formulas which contain the alphabetical
A mixture consists of a combination of two or more compounds or elements or compounds and elements which are physically intermingled. The components of a mixture are not
