Balance the following reaction under basic conditions. What are the coefficients in front of H2O and Cl- in the balanced reaction?
Cl2(aq) + Br2(l) → BrO3-(aq) + Cl-(aq)

3Br2 + 6OH- → 5Br- + BrO3- + 3H2O

Explanation:

We first write the skeletal equation: Br2 → Br- + BrO3-

Next we obtain the oxidation and reduction half equation

Oxidation

Br2 + 12OH- → 2BrO3- 10e- + 6H2O

Reduction

5Br2 + 10e- → 10Br-

Next we put down the overall reaction equation simplifying the coefficients and cancelling electrons gained/lost:

3Br2 + 6OH- → 5Br- + BrO3- + 3H2O

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
