Ah okay, I got it. Thanks.I think it's like this- so in K the reaction is basically the first one right? RCH3 -> RCH2Cl. But you'll notice in the product, there's actually 9 places that Cl could have been put in. It can replace all the hydrogens in the methyl groups. So it becomes 1x9, and the ratio is 21:9.
Woah that was amazing ,and heyy MariammmmmmHey dude how are you ... Long time no see in tutions
So about ur question im gonna explain it to u even though it makes no sesnse at all
Look at step 1 ... a is for h2o2 b is for I- and c is for H+
In the first step h2o2 has appered once so right 1 in the first row of a
I- has appered one in the equation so put 1
And H+ is not there so put zero
For step 2 H2O2 is not there but still u have (1) in the first box so put another one because it was shown in the first step
For I- the same thing ..not shown in step 2 but u already has one from the spfirst step so put another 1
For hydrogen ion this time its shown in step 2 so put 1
For step 3
H2o2 u already has 1 from step 1 so put 1
I- is shown in step 3 and step 1 so put 2 because now u have 2 I- shown
H+ is shown in step 3 and step 2 so in total its shown twice so put 2
Thats it ..hope it hepls
