Answer: Option (D) is the correct answer.

Explanation:

In the equation, number of molecules of carbon, hydrogen and oxygen on the reactant and product side are as follows.

No. of carbon atoms on reactant side = 4

No. of hydrogen atoms on reactant side = 10

No. of oxygen atoms on reactant side = 3

No. of carbon atoms on product side = 1

No. of hydrogen atoms on product side = 2

No. of oxygen atoms on product side = 3

Balance the product side by multiplying no. of carbon atoms with 4 and no. of hydrogen atoms with 5. Therefore, the equation will be as follows.

Now, the no. of oxygen atoms on product side is 8 + 5 = 13. The no. of oxygen atoms on reactant side 2.

Thus, multiplying the no. of oxygen atoms on reactant side by . Therefore, the equation will become as follows.

Multiply the whole equation by 2, then the equation will be as follows.

Thus, we can conclude that the coefficient 12 should be changed by Leslie.

coefficient: they balance the chemical equation you have to make sure the number is as small as it can. It is also used to convert different compounds to compounds or quantities to quantities.

Balance each of the following redox reactions occurring in basic solution.MnO−4(aq)+Br−(aq)→MnO2(s)+BrO−3(aq)Express your answer

Ahat [919]

Answer : The balanced chemical equation is,

$2MnO_4^-(aq)+Br^-(aq)+H_2O(l)\rightarrow 2MnO_2(s)+BrO_3^-(aq)+2OH^-(aq)$

Explanation :

Rules for the balanced chemical equation in basic solution are :

First we have to write into the two half-reactions.
Now balance the main atoms in the reaction.
Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion $(OH^-)$ at that side where the less number of hydrogen are present.
Now balance the charge.

The half reactions in the basic solution are :

Reduction : $MnO_4^-(aq)+2H_2O(l)+3e^-\rightarrow MnO_2(s)+4OH^-(aq)$ ......(1)

Oxidation : $Br^-(aq)+6OH^-(aq)\rightarrow BrO_3^-(aq)+3H_2O(l)+6e^-$ .......(2)

Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.

The balanced chemical equation in a basic solution will be,

$2MnO_4^-(aq)+Br^-(aq)+H_2O(l)\rightarrow 2MnO_2(s)+BrO_3^-(aq)+2OH^-(aq)$
