Answer : The balanced redox reaction will be,
Explanation :
The given chemical equation is,
In the half reaction method, the number of atoms in each half reaction and number of electrons must be balanced.
The half reactions in the acidic medium are :
Reduction : ......(1)
Oxidation : .......(2)
Now multiply the equation (1) by 2 and equation (2) by 3 then added both equation, we get the balanced redox reaction.
Thus, the balanced redox reaction will be,
The smallest unit that make up the matter is atoms.

Explanation: Eh Are you cheating on quiz?
The number of moles of each atom present in 5 moles of Cu₃(PO₄)₂ are:
- 15 moles of Cu
- 10 moles of P
- 40 moles of O
<h3>Description of Cu₃(PO₄)₂</h3>
- 1 mole of Cu₃(PO₄)₂ contains
- 3 moles of Cu
- 2 moles of P
- (2×4) = 8 moles of O
<h3>How to determine the mole of each atom </h3>
The moles of atom present in 5 moles of Cu₃(PO₄)₂ can be obtained as follow
<h3>For Cu</h3>
1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 3 = 15 moles of Cu
<h3>For P</h3>
1 mole of Cu₃(PO₄)₂ contains 2 moles of P.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 2 = 10 moles of P
<h3>For O</h3>
1 mole of Cu₃(PO₄)₂ contains 8 moles of O.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 8 = 40 moles of O
