Question

Write true or false. Correct the false statement.

The properties of a compound are different from those of its constituent elements.

• A. True
• B. False

Answer 1

The correct option is A True

• A compound is a substance made up of two or more elements chemically combined in a fixed proportion by mass.
• Water $\left({\mathrm{H}}_2\mathrm{O}\right)$, for example, is a compound composed of two elements, hydrogen, and oxygen, chemically combined in a fixed proportion of $1:8$ by mass (Atomic masses: $$\begin{gathered} \mathrm{H}=1\mathrm{u},\mathrm{O}=16\mathrm{u}, \\ \mathrm{so}{\mathrm{H}}_2:\mathrm{O}=2\mathrm{u}:16\mathrm{u} \\ \mathrm{or}1:8 \end{gathered}$$.
• The properties of the compound are different from those of its constituent elements. For example - Hydrogen is a flammable gas and Oxygen is the supporter of combustion, while the compound formed by Hydrogen and Oxygen is Water which is inflammable in nature.

Hence, the given statement is True.
