Explanation
Deuterium nucleus contains one proton and one neutron
D2O is called heavy water
As the size of the central atom increases, the bond length between H and the central atom increases, the stability of the hydride decreases
Al is more electropositive than hydrogen, therefore, its oxide will not be reduced by hydrogen
In tritium nucleus there is one proton and 2 neutrons.
H2S is oxidized to S by H2O2
No Solution
H2O2 does not have basic properties.
Nascent hydrogen is associated with chemical energy liberated in the reaction and hence the molecules consist of excess energy
Aqueous solution of H2O2 is neutral to litmus but pure H2O2 is acidic.
Basic character decreases as the size of central atom increases in hydrides of group 15 members
Na2O2 is a peroxide, all others are double oxides (MnO2, SO2) and simple oxide (BaO).
D2O has maximum density at 11.5oC
It is a fact.
H2O2 is not a weak base but a weak acid.
Vol. strength = Normality × 5.6 = 1.5 × 5.6 = 8.4
Atomic NO. = 1,
Atomic mass No. = 1 + 2.
MnO catalyses the decomposition of H2O2
In ice, each H2O molecule is surrounded by four other water molecules, bonded through H-bonds.
Proton (H+) being very small in size would have very large hydration energy
O─O─H bond angle in H2O2 is 97º
Mg2+ and Cl- ions make water hard
In H2O2, there is a single bond between O─O, in O3 there is a resonance between a single and a double bond and in O2 there is a double bond. Therefore the O─O bond length decreases in the order H2O2 > O3 > O2 148 pm 128 pm 121 pm
Last trace of water is removed from H2O2 by crystallization
