Question

two part question please help on both !

part a.

all you have to do is balance equation ..... and put the number of coefficient for each one

When the following half reaction is balanced under basic conditions, what are the coefficients of the species shown?

Br₂+  OH^- BrO₃^-+  H₂O

In the above half reaction, the oxidation state of bromine changes from ___-7-6-5-4-3-2-10+1+2+3+4+5+6+7 to ___-7-6-5-4-3-2-10+1+2+3+4+5+6+7.

part b.

Enter electrons as e-.

Use smallest possible integer coefficients for ALL reactions.

If a box is not needed, leave it blank.

A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge.

Cl₂(g) + 2Fe²⁺(aq) --->2Cl^-(aq) + 2Fe³⁺(aq)

The anode reaction is:

(aq)(s)(l)(g)

+

(aq)(s)(l)(g)

(aq)(s)(l)(g)

+

(aq)(s)(l)(g)

The cathode reaction is:

(aq)(s)(l)(g)

+

(aq)(s)(l)(g)

(aq)(s)(l)(g)

+

(aq)(s)(l)(g)

In the external circuit, electrons migrate _____fromto the Cl^-|Cl₂ electrode _____fromto the Fe²⁺|Fe³⁺ electrode.

In the salt bridge, anions migrate _____fromto the Cl^-|Cl₂ compartment _____fromto the Fe²⁺|Fe³⁺ compartment.
