What are the key differences between carbon monoxide and carbon dioxide? Both of these gases have a lot of similarities â both CO2 and CO are odourless and tasteless. The critical chemical difference is that CO2 contains one molecule of carbon and two molecules of oxygen, whilst CO has one carbon and one oxygen molecule. Carbon dioxide is non-flammable, whilst carbon monoxide is not â we certainly wouldnât encourage you to light a match in order to determine which gas is which.
Carbon atoms are about 25% lighter than oxygen atoms (the ratio of their weights is 3 to 4). What is the weight ratio of the carbon and oxygen that go into the formation of carbon monoxide? Answer the same question for carbon dioxide. Answer: Carbon monxyde has the chemical composition CO, i.e. there is one carbon atom for every oxygen atom; therefore the weight ratio of carbon to oxygen in this compound is just the weight ratio of the atoms, i.e. 3 to 4. In carbon dioxide, , there are two oxyen atoms per carbon atom, so the carbon to oxygen weight ratio in carbon dioxide is 3 to 8. [2.4] Which of these is a pure compound, which is an element, and which is neither: (a) pure water, (b) oxygen gas, (c) liquid mercury, (d) , (e) U, (f) air,
