    yeah that is but the decimal shows about million 9's ....removing to 9's gives us a minute change....which is ignorable..

    the three eq involving the reaction of cfc's with ozone are: a) CFC------(light)---> Cl + FC b) Cl + O3 ------> ClO + O2 c) ClO + O. ------> Cl + O2 in eq (c) oxygen is reacting as reducing agent ..why?

    abcde ..im afraid ur wrong, the number 0.999...... means 0.999999999999999999999999999999999999999999 and so on. In other words an endless chain of 9's so it does not depends on the number of 9's there r after the decimal.. hamidali391: 99.99999........ is subtracted from 0.99999 not 1

    it is a universally accepted that oxygen is an oxidising agent..... in a reaction of CFCs with ozone: ClO + O. -----> Cl + O2 oxygen in the above eq is acting as a reducing agent..........can anyone come up with a satisfactory solution? :shock:

    case 2 has been correctly proved wrong: case 1 is not crap .....study carefully if u wud......case 1 is a method to convert decimals such as 0.67676767.....or 0.345345..... into fractions.....

    o-level maths theory...ruined by chem master

    x=0.999999...... Multiply 100 100x=99.99999...... Subtract: 99x=99 x=1----> X is 0.99999 not 1....theory FAILED! In case 2 x=1 in an eq 2x-2=x-1 2(x-1)=(x-1) 2(x-1)/(x-1)=1 2=1 ----------> 2=1!!! Basic maths FAILED! comin up with other cases so be ready........... ;)
