Deliquescent substances are used for drying because they can absorb and hold a large amount of moisture. Hence, they are often used as drying agents.

Distillation can remove impurities and contaminants from solvents to ensure they meet purity standards for applications like chemical synthesis and manufacturing. it separates solvents from impurities and contaminants, and it can also separate different components of a solvent mixture.

% Volume of O\)_2\) in air = 21% ∴(\(\frac{21}{100}\times30\)) = 6.30 cm\(^3\)

The most common chemical used for coagulation in water purification is aluminum tetraoxosulphate(VI), also known as alum. CuSO\(_4\) is used as a fungicide, algaecide, herbicide, root killer, and soil additive. It can also be used to protect plants during seed treatment. Na\(_2\)SO\(_4\) is used to dry organic liquids. As a filler in powdered home laundry detergents. CaSO\(_4\) is used in tofu(a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness) as a coagulant.

Phosphorus is a highly reactive nonmetal that can easily ignite when exposed to air. It is stored underwater to prevent it from reacting with oxygen and catching fire.

Reduction is gain of electron and decrease in oxidation number. Option D is the only one with addition or gain of electron, as 2 electrons were gained by H ion to become Hydrogen molecule. There is also a decrease in oxidation from +2 to 0. Therefore option D is the correct answer

Since the reaction is an exothermic reaction, the yield of R will be enabled if temperature is decreased. The only way to increase the yield is by removing some of the S produced, while the reactant are being refilled continuously. Option C is the correct answer

M is able to displace Zinc from Zinc Chloride because it is more electropositive than Zinc.

As the temperature increases, so does the kinetic energy of the molecules, which means they move faster. And the faster moving molecules collide more often, which increases the number of collisions per second. This means the collision frequency of the molecules increases. Option D

Al\(^{3+}\) + 3e\(^-\) → Al 3 x 96500 → 27g I = 3600 x 2 → 27 I = (2.7/27) x ((3 x 96500)/(3600 x 2)) = 4.025 ≈ 4

Ethanoic acid with the molecular formular; CH3COOH has the basicity of 1 because it is only one hydrogen ion that can be replaced. Hence, it is monobasic.

\DeltaH = + 89kJ means it is an endothermic reaction. However, endothermic reaction is one in which heat is absorbed into the system from the surrounding.

A reducing agent (also called a reductant or reducer) is an element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized. In the reaction, Copper is oxidized.

When \Delta H is negative, the reaction is said to be exothermic, while it is endothermic when \Delta H is positive.

The more concentrated a solution is, the higher the conductivity is. In most cases it is a proportional relationship. As the ion concentration increases, the conductivity increases.
