In this case, our system is: 2H 2 O( ) + O 2 (g) ←→ 2H 2 O 2 (aq) and it is at equilibrium. The act of adding more H 2 O 2 will force the system to shift left in order to consume the H 2 O 2 and restore equilibrium. 003 5.0 points (Hint: the MW of NaCl is 58.44. And the mass of NaCl in the problem is some integer multiple of this.)
