Question

Explain what is a compound with the help of an example.

Answer 1

Hint: We can classify matter into three types: there are elements, compounds, and mixtures. We have to know that two forms of matter, where the pure substance exists, are elements and compounds. Elements and compounds vary by their compositions. This is the reason why classification of matter is significant.

Complete answer:
At the point when at least two components chemically combine a fixed proportion by mass, the derived product is known as a compound. Compounds can be characterized as substances consisting of at least 2 unique types of components in a fixed proportion of its atoms. At the point when the components consolidate, some individual property of the components is lost and the recently produced compound has new properties.
Chemical Formula: Compounds are addressed by their chemical formula. A chemical formula is a symbolic representation of the ratios of atoms that comprise a specific chemical compound.
The chemical equation of water is ${H_2}O$ which shows two atoms of hydrogen and one atom of oxygen have consolidated to frame one atom of water. The chemical formula for normal salt is $NaCl$ which shows one atom of sodium and one atom of chlorine join to frame one atom of $NaCl$.
Compounds can be arranged into two sorts, molecular compounds and salts. In molecular compounds, the molecules tie each other through covalent bonds. In salts, it is held along with ionic bonds. These are the two sorts of bonds out of which each compound is made of.
Examples of compounds include methane, sodium chloride etc.

Note:
One should not get confused between element and compound. An element is the simplest chemical entity where the same atoms are present whereas a compound is a substance that is formed when two elements (or) more than two elements are combined in a specific ratio.
