Type: Match the Following-match the column-Medium-Class 11

Match Column-I with Column-II.

Column-IColumn-II
(a) Law of Conservation of Mass(i) Equal volumes of gases at the same temperature and pressure contain equal number of molecules.
(b) Empirical Formula(ii) Ratio of elements in a compound in simplest form.
(c) Avogadro's Law(iii) Mass is neither created nor destroyed in a chemical reaction.
(d) Molecular Mass(iv) Sum of atomic masses of all atoms in a molecule.
A

a-iii, b-ii, c-i, d-iv

B

a-ii, b-iii, c-i, d-iv

C

a-iii, b-iv, c-i, d-ii

D

a-iii, b-i, c-ii, d-iv

Correct Answer

Option A

Detailed Explanation

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction (a-iii). The Empirical Formula represents the simplest ratio of elements in a compound (b-ii). Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain equal number of molecules (c-i). Molecular Mass is the sum of atomic masses of all atoms in a molecule (d-iv).
