| Methane demonstration Senior chemistry worksheet. |
|
Methane reacts with oxygen according to the chemical equation below. CH4(g) + 2O2(g) => CO2(g) + 2H2O(l)
|
|
If all volumes are measured at the same temperature and pressure, what volume of oxygen is required for the complete combustion of 20cm3 of methane?
|
|
| If 20cm3 of methane reacts with 100cm3 of oxygen, what volume of oxygen remains after the reaction is complete? | |
| If 40cm3 of methane reacts with 100cm3 of oxygen, what volume, in cm3 , of each gas remains after the reaction is complete? Hint look at the states of each reactant and product. | |
| If methane reacts with oxygen, according to the equation above, what can we conclude about the volume and mass of products compared with the total mass and volume of reactants? | |
| When methane reacts with oxygen, according to the equation above, what can we conclude about the mass of products compared with the mass of methane that reacted? | |
