Answer:

Explanation:
Subscripts are numbers written after elements, subscripts indicate how many of each atom there are in a compound.
The least common multiples of 4, 10, and 16 is 80.
The answer is C Does it propaget
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 .
