Question:31
Ice and water have different structures and since water expands on freezing the volume of the same amount to ice is more than that of liquid water. Therefore, the density of water is much higher than that of ice and therefore, ice will float on water.
Question:33
Give reasons:
(i) Lakes freeze from the top towards the bottom.
(ii) Ice floats on water.
Answer:
The lake freezes from top to bottom because the temperature during winter keeps on decreasing, and the movement of water happens in such a way that the cold water is heavier and so it sinks to the bottom. While warm water replaces it by coming on the surface. The process repeats until the temperature decreases below 4 degrees and the lake keep on freezing from top to bottom.
Density of ice is less than water due to its structure which forms empty spaces between the water molecules, 4 atoms of Hydrogen surround 1 of oxygen, and therefore make ice float on water
Question:34
What do you understand by the term ‘auto protolysis' of water? What is its significance?
Answer:
Autoprotolysis is the process when two similar molecules react with each other to produce products that are called ions with Proton transfer.

Viscosity/centipoise | 0.8903 | 1.107 |
On the basis of this data explain in which of these liquids intermolecular forces are stronger?
Answer:
The given properties such as boiling point, enthalpy of vaporization and viscosity are all dependent on the intermolecular forces of the liquids. Water has a lower intermolecular force of attraction as compared to , and thus the values are lower for water.
Question:42
Deuterium (D) is the isotope of Hydrogen which contains one proton and one neutron. Thus, on the reaction of water with deuterium, heavy water (deuterium oxide) is produced. Deuterium’s bond is stronger than the normal hydrogen bond, and thus reacts more with deuterium than oxygen.
Question:43
Explain why HCl is a gas and HF is a liquid.
Answer:
F is a stronger electronegative than chlorine, and so forms a stronger bond with Hydrogen than chlorine. In order to break HF bonds, more energy is required as compared to break HCl bonds. This is the reason why HF has a higher boiling point than HCl and is a liquid at room temperature.
Question:44
The first element is Hydrogen, and its molecular form is dihydrogen, so when it reacts with oxygen, it forms water, which is physical solid-state is ice and has a density lower than water, so it floats on water. Water has an amphoteric nature which acts as a base went around acids and vice versa.

Question:46
Give reasons why Hydrogen resembles alkali metals?
Answer:
Hydrogen has a specific unique electronic configuration which is similar to alkali metals but belongs to group 1 in the periodic table. Its strong nature like the alkali metals due to its configuration makes it give one electron to combine to form unipositive ions.
Question:47
Hydrogen generally forms covalent compounds. Give reason.
Answer:
Due to its configuration, Hydrogen also resembles certain halogens, given its ionization enthalpy. Therefore, when acting as a halogen, it forms hydrides by combining with the elements to form a diatomic molecule along with covalent compounds.
Question:48
Why is the ionisation enthalpy of Hydrogen higher than that of sodium?
Answer:
Hydrogen has a higher ionization enthalpy than sodium because sodium has a different configuration that is in the last shell, the electron is in 3s, which if lost, the configuration resembles neon, which is the noble gas. However, with Hydrogen, the case is different, and the electron is in the 1s orbital which on losing doenot amount to attainement of noble gas configuation.
Question:49
Hydrogen is an excellent source of energy. It can be alternate only used as fuel to empower automobiles and generate nuclear energy. It is looked at as a possible option and economy are the run using Hydrogen as a fuel can be called as a hydrogen economy.
