Good morning have a beautiful day

Answer 2

pMnO4−(aq)+qI−+xH2O(l)→rMnO2(s)+sI2(s)+yOH−(aq)

in a balanced chemical reaction number of all atoms at right side should be equal to the left side of the reaction.

Balancing a chemical reaction as:

Step 1: Assign oxidation numbers to each of the atoms in the equation and write the numbers above the atom as:

Mn+7O4−(aq)+I−−1+H2O(l)→Mn+4O2(s)+I20(s)+OH−(aq)

Step 2: Identify the atoms that are oxidized and those that are reduced as:

Reduction: Mn+7O4−(aq)→Mn+4O2(s)

Oxidation: I−−1→I20(s)

Step 3: oxidation-number change is:

Reduction: Mn+7O4−(aq)→Mn+4O2

Please go through the above given answer
