Stoichiometry
So I have this question it reads Consider the generic chemical reaction How many moles of B are required to completely react with 2A + 3B ==> 3C 1. 6 mol of A 2. 2 mol of A I won't put them all just guide me in the right direction please

Stoichiometry
Consider the reaction between reactants S & O2 2S(s) + 3 O2(g) ==> 2 SO3(g) If a reactant vessel initially contains 5 mol S and 9 mol O2, how many moles of S, O2 and SO3 will be in the reaction vessel once the reactants have reached as much as possible? Assume 100% actual y...

Find the limiting reactant for the initial quantities of reactants 2k(s) + Cl2(g)--> 2KCl(s) 1.8 mol K; 1 mol Cl2 I'm lost

Stoichiometry
For each precipitation reaction, calculate how many grams of the first reactant are necessary to completely react with 17.3 g of the second reactant. 2KI(aq) + Pb(NO3)2(aq)--->PbI2(s) + 2KNO3(aq) Not looking for the answer I really want to know if I did it correctly 17.3g P...

Chemistry
Is it true that Na+ and K+ are always spectator ions in reactions that involve sodium and potassium compounds

Chemistry
What does it mean by aq excess and is this something I need to pay attention to. Does it help me balance the equation

Chemistry
I need help balancing this problem HClO3(aq excess) + CaCO3 I got to HCO3 + CaCiO3

Chemistry
Calculate the number of moles in 22.6 g C3H7OH 22.6g C3H7OH x 1 moL C3H7OH /60.11g C3H7OH = 0.375 molC3H7OH Am I right
