Answer 1

Answer:

The balanced chemical equation in acidic medium is given by:

Br2+5H2O2→2BrO3−+4H2O+2H+

Answer 2

Note :- firsty find the electron of each Element compound given there and then identify the oxidation ( loss of electrons) and reduction ( gain of electrons) and then read Rule to balance Reaction by ions electron method.

Explanation:

In order to balance chemical reaction by ion electron method we use Some following rules are The ion-electron method for balancing equations is done in roughly eight steps :-

Step1. Find the the oxidation states of each species and If the reaction equation is written in molecular form, then the equation must be written in ionic form, so balance the number of electrons.

Note:- (1) of attachment is how the oxidation state i.e, +5 of Bro3.

Step2. The reaction is divided into two half reactions with the help of ions and electrons so balance then and write there number of electrons lost and gained also mention half-oxidation reaction and half-reduction reaction also Balance the atoms that change their oxidation states.

Note:- (4) of attachment is Half oxidation reaction and (5) is the half Reduction reaction.

Step3. verify the given reaction by substitute and add all of the charges and atoms on each side. In the case of oxidation reaction, oxidant is written to the left of the arrow and reducing substance is written to the right.

Note : See (7) and (6)

Step4. The number of electrons is written to the right of the arrow to denote the exclusion of electrons in the oxidation half reaction and then Balance the charges by using H+ (in acidic solution) or OH- (in basic solution).

Balance the rest of the atoms (H's and O's) using H2O.

Note: See (7)

If It's not yet balanced then follow below rules.

Step5. Then each half reaction is balanced. A few steps are followed to balance this two half reaction.

Step6. The charge is then equalized on both sides of each half reaction.

On the side where the negative charge is less, the charge on both sides is equalized by adding electrons.

Step7. To equalize the number of electrons in two half reaction, one or both of the two reactions are multiplied by the smallest number required.

Step8. Equilibrium equations are obtained by adding the two equilibrium half reaction thus obtained and subtracting the common substances from both sides.
