Which of the following is a true structure of \(H_2O_2\) ?
1
2
3
4
Explanation:
The structure of \(H _2 O _2\) is not planar but open book structure. The \(O - O - H\), bond angle is \(101.5^{\circ}\) and the \(O - O\) single bond distance is \(1.48 \mathring A\).

\(H_2O_2\) restores the color of old Lead paintings, blackened by the action of \(H_2S\) gas by
1 Converting \(PbO_2\) to \(Pb\)
2 By oxidising \(PbS\) to \(PbSO_4\)
3 Converting \(PbCO_3\) to \(Pb\)
4 Oxidising \(PbSO_3\) to \(PbSO_4\)
Explanation:
\(H_2O_2\) bleaches by oxidation it converts \(PbS\) (black) to \(PbSO_4\) (white)

Triple point of water is ................. \(\mathrm{K}\)
1 \(273\)
2 \(373\)
3 \(203\)
4 \(193\)
Explanation:
(a)The triple point of any substance is that temperature and pressure at which the material can exist in all three phases (Solid, liquid and gas) in equilibrium specifically the triple point of water is \(273.16\,K\) at \(611.2\,Pa\).
