Using relation of mole and given mass, we get
Mass of CO 2 = 1.848 g.
Answer :
Let the composition of liquid A (mole fraction) be x A .
So mole fraction of B will be x B = 1 - x A .
Given that,
Using Raoult’s law ,
Putting values of p total and vapour pressure of pure liquids in the above equation, we get :
600 = 450.x A + 700.(1 - x A )
or 600 - 700 = 450x A - 700x A
or x A = 0.4
and x B = 0.6
Now pressure in vapour phase :
= 450(0.4) = 180 mm of Hg
= 700(0.6) = 420 mm of Hg
And mole fraction of liquid B = 0.70

Answer :
Total amount of mixture of Na 2 CO 3 and NaHCO 3 = 1 g.
Let the amount of Na 2 CO 3 be x g.
So the amount of NaHCO 3 will be equal to (1 - x) g.
Now it is given that it is an equimolar mixture.
So, Moles of Na 2 CO 3 = Moles of NaHCO 3 .
or
or x = 0.558 g
So
and
It is clear that for 1 mol of Na 2 CO 3 2 mol of HCl is required, similarly for 1 mol of NaHCO 3 1 mol of HCl is required.
So number of moles required of HCl = 2(0.00526) + 0.0053 = 0.01578 mol
It is given that molarity of HCl is 0.1 which means 0.1 mol of HCl in 1l of solution.

Q2.10 What role does the molecular interaction play in a solution of alcohol and water?
Answer :
Both alcohol and water individually have strong hydrogen bonds as their force of attraction. When we mix alcohol with water they form solution due to the formation of hydrogen bonds but they are weaker as compared to hydrogen bonds of pure water or pure alcohol.
Thus this solution shows a positive deviation from the ideal behaviour.
Q2.11 Why do gases always tend to be less soluble in liquids as the temperature is raised?
Answer:
It is known that dissolution of gas in a liquid is an exothermic process. So, by Le Chatelier principle we know that equilibrium shifts backwards as we increase temperature in case of exothermic process. Thus gases always tend to be less soluble in liquids as the temperature is raised.
Q2.12 State Henry’s law and mention some important applications.
Answer :
According to Henry's law at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of solution or liquid.
i.e., p = k h x, Here k h is Henry’s law constant.
Some of its applications are as follows:-
(a) We can increase the solubility of CO 2 in soft drinks, the bottle is sealed under high pressure.
(b) To avoid bends (due to blockage of capillaries) and the toxic effects of high concentrations of nitrogen in the blood, the tanks used by scuba divers are filled with air diluted with helium (11.7% helium, 56.2% nitrogen and 32.1% oxygen).
(c) The partial pressure of oxygen is less at high altitudes than that at the ground level. This leads to low concentrations of oxygen in the blood and tissues climbers. Due to low blood oxygen, climbers become weak and unable to think clearly which are symptoms of a condition known as anoxia.
Answer :
Using Henry's Law we can write,
Putting value in this equation, we get :
So, the magnitude of k is .
Now, we will again use the above equation for .
So the required partial pressure is :-
or
Answer :
Positive and negative deviation: - A non-ideal solution is defined as a solution which does not obey Raoult’s law over the entire range of concentration i.e., and . The vapour pressure of these solutions is either higher or lower than that expected by Raoult’s law. If vapour pressure is higher, the solution shows a positive deviation and if it is lower, it shows a negative deviation from Raoult’s law.
Enthalpy relation to positive and negative deviation can be understood from the following example:-
Consider a solution made up of two components - A and B. In the pure state the intermolecular force of attraction between them are A-A and B-B. But when we mix the two, we get a binary solution with molecular interaction A-B.
If A-B interaction is weak than A-A and B-B then enthalpy of reaction will be positive thus reaction will tend to move in a backward direction. Hence molecules in binary solution will have a higher tendency to escape. Thus vapour pressure increases and shows positive deviation from the ideal behaviour.
Similarly, for negative deviation, A-B interaction is stronger than that of A-A and B-B.
Answer :
It is given that of aq. solution. This means 2 g of non-volatile solute in 98 g of H 2 O.
Also the vapour of water at normal boiling point = 1.013 bar.

Molar mass of heptane = 7(12) + 16(1) = 100 unit.

Mole fraction of heptane = 0.456 and mole fraction of octane = 0.544
Now we will find the partial vapour pressure:-
(i) of heptane :-
(ii) of octane :-
So total pressure of solution =
= 47.97 + 25.46 = 73.43 KPa
Answer :
It is asked the vapour pressure of 1 molal solution which means 1 mol of solute in 1000 g H 2 O.
Moles in 1000g of water = 55.55 mol. (Since the molecular weight of H 2 O is 18)

hello,
Yes you can appear for the compartment paper again since CBSE gives three chances to a candidate to clear his/her exams so you still have two more attempts. However, you can appear for your improvement paper for all subjects but you cannot appear for the ones in which you have failed.
I hope this was helpful!
Good Luck
Hello dear,
If you was not able to clear 1st compartment and now you giving second compartment so YES, you can go for your improvement exam next year but if a student receives an improvement, they are given the opportunity to retake the boards as a private candidate the following year, but there are some requirements. First, the student must pass all of their subjects; if they received a compartment in any subject, they must then pass the compartment exam before being eligible for the improvement.
As you can registered yourself as private candidate for giving your improvement exam of 12 standard CBSE(Central Board of Secondary Education).For that you have to wait for a whole year which is bit difficult for you.
Positive side of waiting for whole year is you have a whole year to preparing yourself for your examination. You have no distraction or something which may causes your failure in the exams. In whole year you have to stay focused on your 12 standard examination for doing well in it. By this you get a highest marks as a comparison of others.
Believe in Yourself! You can make anything happen
All the very best.
Hello Student,
I appreciate your Interest in education. See the improvement is not restricted to one subject or multiple subjects and we cannot say if improvement in one subject in one year leads to improvement in more subjects in coming year.
You just need to have a revision of all subjects what you have completed in the school. have a revision and practice of subjects and concepts helps you better.
All the best.
If you'll do hard work then by hard work of 6 months you can achieve your goal but you have to start studying for it dont waste your time its a very important year so please dont waste it otherwise you'll regret.
Yes, you can take admission in class 12th privately there are many colleges in which you can give 12th privately.
