How much quantity of water will be produced when electric spark is made in a mixture of 20 gm H_2 and 200 gm O_2 ? State the composition of products obtained.

How much quantity of heat will be evolved when 10 amp electric current is passed through a 30Omega resistance for 5 minutes?

30 mL of a mixture of CO and CO_(2) , mixed with 10 mL of oxygen, was exploded by electric spark. The gas mixture produced was mixed with KOH solution and thoroughly shaken. 5 mL of oxygen was left behind. What was the composition of the original mixture [volume was measured at STP].

What happens when mixture of CO_2 and NH_3 gas is passed through a slurry of powdered gypsum in water?

50g of antifreeze (ethylene glycol) is added to 200 g water. What amount of ice will separate out at -9.3^@C ?

4.5 g Al is produced at the cathode during the electrolysis of molten Al_(2)O_(3) . If the same amount of electricity is passed through acidulated water, then at STP the volume of liberated oxygen at the anode would be -

5 mL of a gas composed of hydrogen and carbon is mixed with 30 mL of oxygen and exploded with electric sparking. The volume of the gas mixture, obtained by explosion is found to be 25 mL. KOH is then addded to the mixture and as a result, its volume is reduced to 15 mL. the residual gas is purely oxygen. all volumes have been measured at STP. what is the molecular formula of the gas?
