So here is my first question
In the combustion of a certain hydrocarbon, 16.0 grams of CO2 is produced. This represents a 75% yield. What is the theoretical yield?
A) 12g
B)21.3g
C)32.0g
D)44.0g
I know the answer but i don't know how to get it. Thanks in advance.

My second is this
Barbecues burning charcoal briquettes are unsafe for indoor use because of the colourless, odourless, poisonous gas produced.
(a) Find the n(O2) gas that reacts with 3.5 g of
charcoal briquettes (assume pure C) to produce
carbon monoxide.
(b) If there is a plentiful supply of air, a safe
colourless, odourless gas is produced. Find the mass of this gas produced if the same amount of charcoal is burnt. You will need to write another equation.

Oh by the way if i am in the wrong forum again. Notify me and let me copy what i typed in that would save alot of time. Before you delete it.
