A certain gaseous mixture contains methane and sulphur dioxide in ratio of 1:8 by mass. The ratio of the number of molecules is :-
The gas 'A' decomposes as A rarr B + 5C A partially decomposed gaseous mixture is allowed to effuse through a pin hole and the gas coming out initially was analysed. The mole fraction of C in effused gas was found to be 0.6. Determine : (a) ratio of ratio of effusion of 'C' and 'B' (b) the precentage of dissociation of 'A'. (Give answer excluding the decimal places) [Given : Molecular mass of A = 360, Molecular mass of C = 40] Hence, fill OMR answer of (a) and (b) with the value of ((b))/((a))

Read the first activity ,read the extract and then do the all the activites : We were an agrarian people . And my main hoddy in my early teens was to wander through paddy fields to see the different kinds of birds and how they nest. On the se had been many coconut trees and blacks palm trees. Beautifully crafted nests of the weaver-birds - thoookkanaam kuruvikal - would be seen dangling from the ends of plam leaves. Hunderds fo these little birds would land on the the paddy to squeeze the milk form the tender rice. They would come to the field when the young stalks come out of the rice-plants. At this stage of the paddy, my father would send me to our filed with a tin drum to scare these little birds balancing on the tender stalks and squeezing the milk their sharp beaks and fly aways with the stalks dangling in their beaks. I have alawys liked to see this sights also. The nests of parrots were crafted holes in the trunks of plam trees. I continued to wonder how they made these holes on the hard trunks until I saw the patient work of the woodpeckers. They were the carpenters and their longs, sharp and strong beaks, chisels. They make the holes ( in search of worns inside the weak spots of the trunks) and the parrots occupy them . If I heard the sound tak, tak , tak I knew it was a woodpecker chiselling a hrad trunks. I would go after him . It seems that the woodpecker is the only bird which can walk perpendiculary on the tree trunks! How beautiful the sight was !
