## Dalton's Law MCQ Basic Level

Compared to other sections, Chemistry is considered to be the most scoring section. If prepared thoroughly, chemistry can help students to secure a meritorious position in the exam. These questions are very important in achieving your success in Exams after 12th.

Q1. The total pressure exerted by a number of non-reacting gases is equal to the sum of the partial pressures of the gases under the same conditions is known as

•  Boyle's law
•  Charle's law
•  Dalton's law

Dalton's law

Q2. “Equal volumes of all gases at the same temperature and pressure contain equal number of particles.” This statement is a direct consequence of

•  Charle's law
•  Ideal gas equation
•  Law of partial pressure

Q3. Dalton's law of partial pressure will not apply to which of the following mixture of gases

•  H2 and SO2
•  H2 and Cl2
•  H2 and CO2
•  CO2 and Cl2

H2 and Cl2

Q4. Which of the following mixtures of gases does not obey Dalton's law of partial pressure

•  O2 and CO2
•  N2 and O2
•  Cl2 and O2
•  NH3 and HCl

NH3 and HCl

Q5. Equal volumes of two gases which do not react together are enclosed in separate vessels. Their pressures at 100 mm and 400 mm respectively. If the two vessels are joined together, then what will be the pressure of the resulting mixture (temperature remaining constant)

•  125 mm
•  500 mm
•  1000 mm
•  250 mm

250 mm

Q6. Same mass of CH4 and H2 is taken in container. The partial pressure caused by H2 is

•  8/9
•  1/9
•  1/2
•  1

8/9

Q7. Equal amounts of two gases of molecular weight 4 and 40 are mixed. The pressure of the mixture is 1.1 atm. The partial pressure of the light gas in this mixture is

•  0.55 atm
•  0.11 atm
•  1 atm
•  0.12 atm

1 atm
