Just how and why they are proportioned and what part of the equation is "ratio'd" like i have one question now WHat mass of Carbon Monoxide is produced when 1000kg of TNT is Defused/Decomposed idek haha

It's not hard finding the ratio. You just have to look at the number in front of the reactants/products.

Ok so do they give you an equation for this?
Yep 2 C7 H5 (NO2)3 -> 12CO+5 H2+ 3 N2 + 2 C What ive done is get the Mr of the first part which i got as 227, then divided that by 1000, and have 0.227 no clue what to do next is it a 1:6 Ratio

Are you sure your Mr is right?
Because I'm getting a different answer.
And you would times by 1000 as when you convert kg to g you multiply by 1000.
Please go through the steps involved and why please. Its my first time doing A Level Chemistry :/
Formula CaCO3 -> CO2+CA
CaCO3 → CO2 + CaO
n = m/M n = moles, m = mass, M = molar mass/relative molecular mass (technically, the values of the periodic table added up.) n = 35g / 40.1 + 12 + 3(16) n = 0.350
Ratio of CaCO3 to CO2 1 : 1 (If it was 1 to 2, 1:2, you double, for example, if it was 2 to 1, 2:1, you divide, for example.)
m = nM (or n x M, that's just how I write things.) m = 0.350 x (12 + 2(16)) m = 15.4g
I know it's already been sorted out, but the more ways I see a problem for example, the easier it is to understand.

Thanks! How would i do it for WHat mass of Carbon Monoxide is produced when 1000kg of TNT
and i get 2.27*10^-4, what will i multiply it with from here
Or yeah you could do that haha
(Just as a side note, if you have a weird ratio like 2:3, you can get your moles for e.g. 2.27x10^-4 and then times it by your ratio like this 3/2 as a fraction. This is when you can't simplify)
Now you would times by 6. That will be your new moles for CO. Then you just work out the mass from there by multiplying moles with Mr.

2.27*10^-4)*6=1.362*10^3 then would i times it by (CO =12+16)???
