Reaction 1: CaC2(s) + 2 H2O(l) ⇄ C2H2(g) + Ca(OH)2(s) Reaction 2: NaOCl(aq) + 2 HCl(aq) ⇄ Cl2(g) + N — Stoichiometry Chemistry Question
Question
Reaction 1: CaC2(s) + 2 H2O(l) ⇄ C2H2(g) + Ca(OH)2(s)
Reaction 2: NaOCl(aq) + 2 HCl(aq) ⇄ Cl2(g) + NaCl(aq) + H2O(l)
Reaction 3: C2H2(g) + Cl2(g) ⇄ C2H2Cl2(g)
Reaction 2 occurs when an excess of 6 M HCl(aq) solution is added to 100. mL of NaOCl(aq) of unknown concentration. If the reaction goes to completion and 0.010 mol of Cl2(g) is produced, then what was the molarity of the NaOCl(aq) solution?
A.
0.0010 M
B.
0.010 M
C.✓ Correct
0.10 M
D.
1.0 M
