1. I came across this question which says that CO is formed by
the incomplete combustion of natural gas, which is a fossil fuel.
However, what we learnt is that CO is produced from the incomplete
combustion of carbon-containing fuel. As natural gas consists
mainly methane CH4, does it make this fossil fuel under the
category of carbon-containing fuel?
And may I ask, are ALL fossil fuels carbon-containing fuels?
(coal, natural gas, petroleum (mixture of hydrocarbons), well they
all do contain carbon, don't they?
2. Which gas is not produced when hydrocarbons are burnt in the
internal combustion engine?
A CO2 B CO C
H2 D nitrogen oxides
my guess is D since
hydrocarbons + oxygen -> carbon dioxide + water +heat energy
(in the case of incomplete combustion there's CO)
Now left with C and D. Naturally I eliminated D as hydrocarbons
do not contain nitrogen element.
Answer given is C....
3. which substance reacts with methane?
A chlorine B HCl acid C
NaOH D water
answer is chlorine. I have never heard of such a reaction before
nor seen it anywhere in our chemistry O's syllabus. Is it possible
that someone tell me what happens in this reaction?
Thanks a lot
1. yes
2. nitrogen is also taken in to form nitrogen oxide. plentiful
of nitrogen in the air, 79% of air = nitrogen. since you
already know water come out, how can there still be hydrogen?
