p ml of a mixture of carbonmonoxide carbon dio oxide and nitrogen are mixed with q ml of oxygen.after oxidation r ml of mixture of carbondioxide nitrogen and left over oxygen are obtained.adsorption with alkali metal leaves s ml of residual gases
match gas compostion
1. carbon monoxide a. 2p+2q-2r
2.carbondioxide(before combustion) b. 2r-2p-2q-s
3.carbondioxide (after combustion) c.r-s
4.nitrogen d.p-r+s
pls state ur working thnx.........
1for 1st ans is a
let co in the mixture be x ml
then acc to eqn
co+halfo2 gives co2 on oxidation(co2 n n2 ll not get oxidised)
x ml of co ll react completly with x/2 ml of oxygen to give x ml of co2
remaining mixture=(p-x)+(q-x/2)+x
which is equal to r ml
thus equate and get the ans
