How many electrons does each gold atom gain? How many electrons does each iodine atom lose? What is the total number of electrons that are moved in the oxidation-reduction reaction? Complete the final balanced equation based on the half-reactions.

3 , 1 , 6 , 2 , 6 , 2 , 3 , 6

Explanation:

Half equation:

I. Au3+ + 3e- --> Au

II. 2I- --> I2 + 2e-

Au3+ + 3e- --> Au. ×2

2I- --> I2 + 2e- ×3

2Au3+ + 6e- --> 2Au

6I- --> 3I2 + 6e-

Overall equation

AuI3 --> 2Au + 3I2

A.

3 electrons

B.

2 electrons

C.

6 electrons

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
