What? It would be nice if you show pic
Answer : The correct match is:
1 positive charge = 1 negative charge
2 positive charges = 2 negative charges
3 positive charges = 3 negative charges
Explanation :
As we now that there are three subatomic particles which are protons, electrons and neutrons.
The protons and neutrons are located inside the nucleus and electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and neutrons are neutral.
As we know that all the things are made up of charges and opposite charges attract to each other.
In a neutral atom, the positive charges and negative charges are balanced in an object. That means, in neutral atom the number of positive charges are equal to the negative charges.
So we can say that:
1 positive charge = 1 negative charge
2 positive charges = 2 negative charges
3 positive charges = 3 negative charges
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 .
