Assertion (A):-The PH of acid rain is less than 5.6 Reason (R):-CO2 present in the atmosphere dissolves in rain water and form carbonic acid.

(c) Assertion is correct, reason is incorrect 

CO2 molecule has only two bonds which lie farthest to each other to minimise repulsion, making an angle of 180°.  H2O, on the other hand, has a lone pair. As lone...

(a) Sulphuric acid (H2SO4) reacts very vigorously with water, in a highly exothermic reaction. Thus if you add water to concentrated sulfuric acid, it can boil and you may get...

(b) Formic acid is stronger than acetic acid due to its chemical composition. Formic acid is an organic acid as well as active acid in an organic acid.

In water, CO2 dissolves to form carbonic acid( H2CO3):  CO2(g) + H2O(l)----> H2CO3(aq)  As the reaction is reversible, the solubility is low.  In aqueous NaOH, H2CO3 reacts with sodium hydroxide as follows:  2 NaOH(aq)+...

(c) A = C + 3, D = B – 4, E = F – 6  C = E + 2, F = D + 3  On adding, we get A =...

(B) If both assertion and reason are true, but reason is not the true explanation of the assertion.

(d) Carbon dioxide is one of the important green house gas. It allows the shorter wavelength of infra red radiations to pass through it but does not allow these radiations...

A gaseous mixture of H₂ and CO₂ contain  66 % CO₂ by mass of CO₂ this means if mixture 100g CO₂ =66g  and H₂ =34g Applying Dalton's law : m mix = mH₂...
