    I would just like someone to check my answers for me. Im not sure my molar ratios are right. I'm going off of the info found here


    http://www.ehow.com/how_8149226_calc...lar-ratio.html


    The only thing im missing is the molar ratio for Potassium + Iron (II) Sulphate. Any help on that is welcome.


    Write properly balanced equations for the following reactions. State the molar ratios of the reactions.


    Sodium Hydroxide + Phosphoric Acid
    3NaOH + H3PO4 → Na3PO4+3H2O
    Molar ratio =3:1


    Methane + Oxygen
    CH4 + 2O2 → CO2 + 2H2O
    Molar ratio = 2:1


    Zinc + Sulphuric Acid
    Zn + H2SO4 → ZnSO4 + H2
    Molar ratio= 1:1


    Ammonia + Hydrochloric Acid
    NH3 + HCl → NH4Cl + H2O
    Molar ratio = 3:1


    Sodium bicarbonate + Phosphoric Acid
    H3PO4 + 3NaHCO3 → Na3PO4 + 3CO2 + 3H2O
    Molar ratio = 3:1


    Potassium + Iron (II) Sulphate
    MnO4- + 8H+ + 5Fe+2 → Mn+2 + 5Fe+3 + 4H2O
    Molar ratio = ???


    Iron + Hydrochloric Acid
    Fe + 2HCl → FeCl2 + H2
    Molar ratio = 2:1


    Nitric Acid + Magnesium Hydroxide
    2HNO3 + Mg(OH)2 → Mg(NO3)2 + 2H2O
    Molar ratio = 1.5:1

    Calculate the molecular weights of the following compounds
    CuNO3 = 125.551 g/mol
    KOH = 56.105 g/mol
    Fe = 55.845 g/mol
    H3PO4 = 97.995 g/mol
    CO2 = 44.009 g/mol
    CH4 = 16.042 g/mol
    Na2SO4 = 142.042 g/mol
    LiOH = 23.948 g/mol
    Ca3(PO4)2 = 310.176 g/mol
