Hello, how would i solve the following?: "How many litres of air (78% N2, 22% O2 by volume) are needed for the combustion of 1 litre of octane, C8H18, a typical gasoline component, of density 0.70g/mL?" Note - 1 mole of oxygen gas is equal to 24.5 litres. I have done the chemical...

Hi I was wondering what would be the equation for the rusting of magnesium? I did an experiment where an iron nail was covered by a strip of magnesium and was put into diluted NaOCl (diluted sodium hypochlorite solution). Apparently the magnesium protects the iron from rusting and hence rusts...

Hi everyone, I'm not sure what would happen in the following reaction (it has something to do with the rusting of iron): Fe (s) + KMnO4 (aq) ----> ? KMnO4 is potassium permanganate and I know it is a very strong oxidizer. So I am assuming one of the products may be Fe2O3, which is...
