Answer:
The answer is most likely compound a
Explanation:
Covalent compounds have low melting and boiling points and conduct electricity poorly
The balanced skeleton reactions are given below
2CrO₄²⁻(aq) + 3Cu(s) +8
(l) → 2Cr(OH)₃(s) + 3Cu(OH)₂(s) + 6
(aq)
The oxidising agent and reducing agents are Cr and Cu .
There are following steps involve in balance redox reaction in basic medium .
- First divide the reaction into two half reactions which give oxidation and reduction half reaction.
- Then balance the elements other than oxygen and hydrogen atom.
- Balance the oxygen atom by adding
where number of oxygen is less .
- Balance the hydrogen atom by adding
on another side of where water molecule added. - Add
ions to both sides to neutralize
ion. - Combine
and
ion to make
.
- Balance the charge by adding
.
The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction is called reducing agent .

The ground state electron configuration of ground state gaseous neutral tin is 4d to the power of 10. 5s to the power of 2. And 5p to the power of 2. And the term symbol is 3P0
Bohr's Model agree with Thompson's model because Bohr concluded that packets of energy are absorbed or emitted by the atoms when an electron changes shell. Thompson's conclusion states that atoms have small, negatively charged particles (referring to Electrons) as part of their internal structure.
