According to the balanced chemical reaction, we have one mole of methane reacting with four moles of cl2 to produce one mole of ccl4 and four moles of hcl.
00:18
So to answer the question, the blanks are going to be one mole ch4, four moles cl2, one mole ccl4, and four moles hcl.
00:38
Then for part b, we're given a separate reaction.
00:43
This reaction is h2o2 going to h2o and o2.
00:52
We need to balance it first.
00:58
We have two oxygens, so to get two oxygens over here, we need to multiply this by one -half.
01:09
We can get rid of that one -half by multiplying everything by two, and then two times one -half gives us one.
01:18
So now it's balanced.

So what mass of hydrogen peroxide must decompose to produce 24 .32 grams of water? well now that we have a balanced chemical reaction, we can convert the grams of water into moles of water using the molar mass of water, 18 .015 grams...
