Explanation

Chlorofluorocarbons (CFCs) release chlorine atoms in the stratosphere, which break down ozone (O₃) molecules.

This reaction is the main cause of ozone layer depletion.

Explanation

Oxidative phosphorylation is the process of ATP synthesis using energy from electrons transferred through the electron transport chain in the presence of oxygen.

It occurs in the mitochondria.

It is the main source of ATP in aerobic respiration.

Explanation

The coordination number of a metal atom in a complex is the number of ligands directly attached to it.

In [PtCl(NO)(NH₃)₂], the ligands are:

• Cl⁻ (1)
• NO (1)
• NH₃ (2)

Total number of ligands = 1 + 1 + 2 = 4

The coordination number of Pt is 4, since it is bonded to 4 ligands.

Explanation

Elasticity is the property of a body that enables it to return to its original shape after the deforming force is removed.

Materials like rubber show high elasticity, while clay does not.

Explanation

The 5th term of the given geometric progression (G.P.) is 48. The sequence is 3, 6, 12, ...

The common ratio is 2 (6/3 = 2, 12/6 = 2).

Using the formula for the nth term of a G.P., a_n = a * r^(n-1),

where a is the first term and r is the common ratio, the 5th term (a_5) is 3 * 2^(5-1) = 3 * 2^4 = 3 * 16 = 48.
