Formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.
<h3>What are the three conditions under which ionic reactions completed?</h3>
The three conditions under which ionic reactions can run to completion i.e. formation of a gas, formation of a precipitate and formation of a slightly ionized product.
K+(aq) + Br−(aq) + Ag+(aq) + C2H3O2−(aq) → K+(aq) + C2H3O2−(aq) + AgBr(s)
Mg2+(aq) + SO42−(aq) + Ba2+(aq) + 2NO3−(aq) → Mg2+(aq) + 2NO3−(aq) + BaSO4(s)
So we can conclude that formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.

D. Loss of the upward force opposing gravity
Explanation:
A hanging apple from a tree branch will fall when it loses the upward force opposing gravity. The force of gravity is directed towards the center of the earth and it pushes all bodies downward.
On the apple, the forces acting on it are:
- downward force of gravity
- Upward force holding it by the fruit stalk.
According to Newton's first law "a body will remain in it's state of rest or uniform motion unless an external force acts on it "
The apple is initially at rest when the force of gravity equals the upward force :
Force of gravity = Upward force
The two forces acts in opposite direction and cancel out.
When the downward force is lost by stalk holding the fruit, gravity wins and the fruit falls;
Force of gravity - Upward force = Net force = falling of the fruit
In case we push up the fruit, the upward force overcomes and it moves upward:
