A reaction mixture

P4(s)+6Cl2(g)→4PCl3(l) A reaction mixture initially contains 45.13 g P4 and 132.0 g Cl2.Once the reaction has occurred as completely as possible, what mass (in g) of the excess reactant is left?

What volume of 0.200 M ethanol solution contains each of the following number of moles of ethanol:0.45 mol ethanol, 1.23 mol ethanol, 1.5×10−2 mol ethanol

A 61.5mL sample of a 0.106M potassium sulfate solution is mixed with 37.5mL of a 0.104M lead(II) acetate solution and the following precipitation reaction occurs: K2SO4(aq)+Pb(C2H3O2)2(aq)→2KC2H3O2(aq)+PbSO4(s) The solid PbSO4 is collected, dried, and found to have a mass of 1.00g
