Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese (IV) oxide. 4 HCl(aq) + MnO₂ (s) → MnCl₂ (aq) + 2 H₂O(l) + Cl₂ (g) A sample of 42.5 g MnO₂ is added to a solution containing 50.9 g HC1. What is the limiting reactant? O MnO₂ HC1 What is the theoretical yield of Cl₂? theoretical yield: If the yield of the reaction is 84.1%, what is the actual yield of chlorine? actual yield: g Cl₂ g Cl₂

Sodium bicarbonate can be used to neutralize stomach acid, HCl(aq) and costs approximately 50 cents per pound at a grocery store. Your stomach acid is approximately 0.100M HCl.  NaHCO3(s) + HCl(aq) --> NaCl(aq) +CO2(g) + H2O(l)  From the balanced molecular equation , how many milligrams of sodium bicarbonate (Molar mass = 84.01 g/mol) can neutralize 125. mL of a 0.100M  hydrochloric acid solution ?

What mass of precipitate (in g) is formed when 80.0 mL of 0.500 M AlCl₃ reacts with excess AgNO₃ in the following chemical reaction? AlCl₃(aq) + 3 AgNO₃(aq) → 3 AgCl(s) + Al(NO₃)₃(aq)

Consider the following balanced equation:2 H3PO4 (aq) + 3 CaCO3 (aq) → 3 Ca(PO4)2 (aq) + 3 H2O (l) + 3 CO2 (g)A commercial rust remover contains 7.30 mol/L of phosphoric acid, H3PO4.Calculate the mass of calcium carbonate scale inside a coffee maker that can be dissolved(reacts completely) by reacting with 45.0 mL of the phosphoric acid solution.
