`20mL` of a mixture of `CO` and `H_(2)` were mixed excess of `O_(2)` and exploded & cooled. There was a volume contraction of `23mL`. All volume measurements corresponds to room temperature `(27^(@)C)` and one atmospheric pressure. Determine the volume ratio `(V_(1):V_(2))` of `CO` and `H_(2)` in the original mixture .

Two mole of Hydrogen and three mole of Helium are mixed at room temperature and at atmospheric pressure P_a and the mixture occupies a volume V.

12 litre of H_2 and 11.2 litre of Cl_2 are mixed and exploded. The composition by volume of mixture is:

100ml of a mixture of CH_(4) and C_(2)H_(4) were exploded with excess of oxygen. After explosion and cooling, the mixture was treated with KOH , where a reduction of 165 ml was observed. Find the composition of the mixture taken ?

A 100 ml mixture of CO and CO_2 is passed through a tube containing red hot charcoal. The volume becomes 160 ml.The volumes are measured under the same conditions of temperature and pressure Amongst the following , select the correct statement(s).

When 20ml of mixture of O_(2) and O_(3) is heated the volume becomes 29ml and disappears in alkaline pyragallol solution. What is the volume percent of O_(2) in the original mixture ? .

40 ml of gaseous mixture of CO and ethyne is mixed with 100 ml of O_2 and burnt. The volume of gases after combustion is 105 ml. The composition of the original mixture is

A mixture of ethylene and excess of H_(2) had a pressure of 600 mmHg the mixture was passed over nickel catalyst to convert ethylene to ethane.The pressure of the resultant mixture at the similar conditions of temperature and volume dropped to 400 mm Hg The fraction of C_(2) H_(4) by volume in the original mixture is

25 " mL of " a mixture of Co, CO_(2) and H_(2) were exploded mL with 10 " mL of " oxygen. The products has a volume of 18.5 " mL of " which 17 mL absorbed by alkali. What was the composition of the original mixture? All volume measurements were made at the same temperature and pressure?

A mixture of H_(2) & O_(2) having total volume 55 ml is sparked in an Eudiometry tube & contraction of 45 ml is observed after cooling. What can be composition of reacting mixture?

60ml of mixture of equal volumes of Cl_(2) and an oxide of chlorine, i.e., Cl_(2)O_(n) was heated and then cooled back to the original temperature. The resulting gas mixture was found to have volume of 75ml . On treatment with KOH solution, the volume contracted to 15ml . Assume that all measurements are made at the same temperature and pressure. Deduce the value of n in Cl_(2)O_(n) . The oxide of Cl_(2) n heating decomposes quantiatively to O_(2) and Cl_(2) .
