A leavening agent used in some older recipes is baking ammonia or ammonium bicarbonate. As it is heated, it breaks down into three gases- ammonia, water, and carbon dioxide. For each 20g of baking ammonia heated, how many grams of carbon dioxide are released?

  1. (NH4)2CO3 ==> 2NH3 + CO2 + H2O

    Convert 20 g (NH4)2CO3 to moles. moles = g/molar mass

    Using the coefficients in the balanced equation, convert moles ammonium carbonate to moles CO2

    Convert moles CO2 to grams. grams = moles x molar mass.

  2. Sorry but I misread the bi part of ammonium bicarbonate.
    The equation should be
    NH4HCO3 ==> NH3 + CO2 + H2O
    Check that to make sure it's right.
    The remainder of the original post is ok.
