Question

Balance the reaction shown below using the smallest possible whole-number coefficients if the reaction is carried out under basic conditions. Make sure that every reactant and product has a coefficient in front of it (even if the coefficient is 1). You will need to add water to one side of the reaction equation in order to balance it. Now pick the correct statement about your balanced reaction equation from the multiple choices.

Cl₂O₇(aq) + C₂O₄^2-(aq) Cl ^-(aq) + CO₂(g)

a) The coefficient in front of H₂O is 18.
b) The coefficient in front of C₂O₄^2- is 9.
c) The coefficient in front of CO₂ is 16.
d) The coefficient in front of Cl ^- is 12.
e) The coefficient in front of Cl₂O₇ is 13.

Answer 1

Correct option is "C" Cl207(aq)+C202(aq) Cl (aq)CO2(g) С,0,2 (aq) CO2(g) Cl (aq) Cl207(aq) 1) Except oxygen and hydrogen atoms and 1) Except oxygen and hydrogen atoms and other atoms balance. other atoms balance +2 CO2(g) C2042 (aq) 2 Cl Cl207(aq) 2) Balance the oxygen atoms 2) Balance the oxygen atoms C2042(aq) 2 CO2(g) 2 Cl7 H20 Cl207(aq) 3) Balance the hydrogen atoms 3) Balance the hydrogen atoms C202 (aq) +2 CO2(g) 2 CI- 7 H20+14 OH Cl207(aq)14 H20 4) Balance the charge 4) Balance the charge 2 e+C2042(aq) 2 CO2(g) Cl2O7(aq)14 H20 2 CI-7 H20 +14 OH 16 e 2) multiply second equation by 8 1) 16 е+ 8 C,042 (ag) 16CO2(g) Solve 1 & 2 Cl207(aq)14 H20 2 CI-7 H20 +14 OH 16 e 16 e+8 C2042(aq) 16CO2(g) 2 Cl +14 OH+16CO2(g) ClO7(aq) + 7 H2C+ 8 С,042 (аq)
