Question

Methane gas burns in air to give carbon dioxide and water.

a) give a chemical equation
b) How can the mixture of these gases be separated

b) Which gases does it mean?? Can anyone tell me..
Pleease.

Answer 1

in this case, water is in gaseous form.

CH4(g)+O2 (g)>>>CO2(g) + H2O(g)

Answer 2

@Bobpursley sir.. so it means that we need to separate carbon dioxide and steam.. right?

Answer 3

That's right. Think what temperature H2O condenses from gas to liquid (or freezes to a solid) vs temperature CO2 condenses from gas to solid.

Answer 4

what is the process of separation?

Answer 5

ok. what do we need to do after both of the gases have been liquified???

Answer 6

can we do it this way : keep the mixture at less than 100 degree C , then the steam will condense into liquid water and co2 stays as gas

Answer 7

i don't know the answer from raghib
