write the chemical equations for the following sentences
a) Aluminum reacts with oxygen to produce aluminum oxide
I put Al + O2 ----------> 2Al2O3
b) Phosphoric acid, H3PO4, is produced through the reaction between tetraphosphorous decoxide and water
I put P4O10 + 6H2O --------> 4H3PO4
c) Iron(III) oxide reacts with carbon monoxide to produce iron and carbon dioxide
I put FeO3 + CO2 ----------> FeCO2

thanks in advance

    A is ok but it isn't balanced. The product is Al2O3. Note you have 1 Al on the left and 2 on the right. You have 2 O on the left and 6 on the right.
    B is ok. Correct product and balanced correctly.
    C is not ok.
    iron(III) oxide is Fe2O3.
    Carbon MONoxide is CO.
    It produces iron (Fe) and carbon dioxide (CO2).

    so A is Al2O3 and c is FeCO2?

  • chemistry proofread - ,

    A is Al2O3 but c is not FeCO2.
    C is Fe AND CO2 as in Fe + CO2.
    Fe2O3+ CO ==> Fe + CO2. It isn't balanced.
