| chemistry lab experiment?
A chemistry lab experiment involves synthesis of magnesium chloride by reacting magnesium bicarbonate with aqueous hydrochloric acid, according to the following unbalanced reaction:
Mg(HCO3)2 (sol) + HCL (aq) -----> MgCl2 (aq) + H2O (liq) + CO2 (gas)
After 30.00 grams of magnesium bicarbonate were reacted with 0.5000 mole of aqueous hydrochloric acid, the reaction mxcture was heated to dryness, leaving a residue with a mass of 19.004 grams.
a) Balance the reaction equation and determine which was the limiting reagent.
b) Calculate the theoretical yield and the percent yield.
c) How many moles of excess reagent were left un-reacted and subsequently boiled away.
