Question

sodium sulfide, Na2S, is used in the leather industry to remove hair from hides. The Na2SO4 + 4C -> Na2S +4CO(g) so suppose you mix 15(g) of Na2SO4 and 7.5g of C. which is the limiting reactant AND what is mass of Na2S that is produced?

two reactants are copper(II)chloride and water what change would you observe in the copper(II)oxide. was there a change in solubility? where is the copper(II) chloride? how can you tell

I think the limiting agent is sodium sulfate...
and the mass of sodium sulfide is 8.268 grams
