Question

The new substances produced by a reaction are called

• A. Reactants
• B. Products
• C. Compounds
• D. Elements

Answer 1

The correct option is B

Products

The explanation for the correct option:

(B) Products :

• It is the new substance that is formed after the reaction between reactant molecules.
• For example, $\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Hydrochloric}\mathrm{acid}}{2\mathrm{HCl}\left(\mathrm{g}\right)}$, here$\mathrm{HCl}$ is the product.

The explanation for the correct option:

(A) Reactants :

• It is the new substance that is formed after the reaction between reactant molecules.
• For example, $\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Hydrochloric}\mathrm{acid}}{2\mathrm{HCl}\left(\mathrm{g}\right)}$, here ${\mathrm{H}}_2,{\mathrm{Cl}}_2$ is the reactant.

(C) Compound: Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio.

• For example, Hydrochloric ($\mathrm{HCl}$) is a combination of Hydrogen($\mathrm{H}$) and Chlorine($\mathrm{Cl}$)

(D) Elements: A species of atoms with the same number of protons in the atomic nucleus and can not be further differentiated into simpler components.

• For example; Sodium($\mathrm{Na}$) element.

Hence, the correct option is an option(B).
