Answer:
C. Br and Cl
Explanation:
The pair that will share electrons when a bond forms between them is Br and Cl.
When electrons are shared between two atoms to form a bond, then the bond type formed is called a covalent bond.
- A covalent bond forms between non-metals.
- Br and Cl are non-metals
- The electronegativity difference between the species must be very low or zero.
- This is the case for the two non-metals.
The $ -(Br) at that instant is calculated as follows
BrO3 + 5Br ---> 3Br2 + 3 H2o
by use of reacting ratio BrO3 to Br2 which is 1:3
therefore $ of Br = 3 x (1.5 x10^-2)= 4.5 x10^-2
