Answer:
i do not know
Explanation:
im taking my final exam right now and need the answer, did you ever figure it out
Reactants are NaHCO3 and HC2H3O2 because they are on the left side of the arrow, aka they’re what’s going in to make the products. NaC2H3O2, H2O and CO2 are the products bc they’re on the right side of the arrow, aka they are the results of the reactants combining
Answer:
24%
Explanation:
From the question, the limiting reactant is H2S.
The reaction equation is;
2H2S + O2 → 2S + 2H2O
Number of moles of H2S reacted = 22g/34 g/mol = 0.647 moles
According to the reaction equation;
2 moles of H2S yields 2 moles of sulphur
0.647 moles of H2S yields 0.647 moles of sulphur
So;
Theoretical yield of sulphur = 0.647 moles * 32 g/mol = 20.7 g
Actual yield = 5 g
% yield = actual yield/theoretical yield * 100
% yield =5 g/20.7 g * 100
% yield = 24%
