13.2 g of Aluminum chloride is produced in the laboratory when 5.40 g Al is reacted with 12.0 g Cl2. What is the limiting reagent (Al or Cl2)? [limiting_reagent] What is theoretical yield? [theoretical_yield] g AlCl3 What is the percent yield? [percent_yield]%   Note the balanced chemical reaction is: 2Al(s) + 3Cl2(g) –> 2AlCl3(s))

Balance the following equation: [coeff_c3h8]C3H8 + [coeff_o2]O2 → [coeff_co2]CO2 + [coeff_h2o]H2O.   Note: If a coefficient is ‘1’ then don’t leave it blank as would on paper – enter ‘1’.

What volume of 1.2 M H2SO4 is required to react completely w/ 15.0 grams of NaOH? Volume of H2SO4: [vol_h2so4] mL (Hint: the unbalanced equation is: H2SO4  + NaOH –> Na2SO4 + H2O)
