Best Answer

iron + water + oxygen ----> hydrated iron(III) oxide

hydrated means it has water molecules "complexed" with the iron(III) oxide - that's why if you heat rust in a test tube you will see steam / condensation being given off

What product is obtained by reaction between aluminium hydroxide and oxalic acid?

Well, when I looked online for the formula for oxalic acid, it said it was H2C2O4. If this is correct the equation would be H2C2O4 + Al(OH)3 --> H2O..... Something... Im not sure about that last part because the oxalic acid formula doesnt seem right to me... But it would be a double-displacement reaction.
