Answer:
its c I think C)
The reason for this is due to the phenomenon called "Charging by Induction". What that means is that when something with a charge, for example a negative charge, is brought near an uncharged one, it induces the opposite charge onto it (positive in this case) and therefore since opposites attract, it attracts it.
The reason for this is that since, just like a positive magnet rejects and pushed away like charges, the electrons hold a negative charge, they push away any electrons that may be in the neutrally charged item causing only protons to be left, thus creating an oppositely charged object. Or vice versa.
So whatever charge the object has, it induces the opposite charge into the uncharged object, causing the charges to move only in the uncharged one.

Explanation:
generally temporary changes are reversible. permanent changes are the changes which remain for a longer time and are not reversible
Answer:-
0.229 L
Explanation:-
Molar mass of AgBr = 107.87 x 1 + 79.9 x 1
=187.77 grams mol-1
Mass of AgBr = 150 grams
Number of moles of AgBr = 150 grams / 187.77 gram mol-1
= 0.8 mol
The balanced chemical equation is
NaBr (aq) + AgNO3 (aq)--> AgBr(s) + NaNO3(aq)
From the equation we can see that
1 mol of AgBr is produced from 1 mol of AgNO3.
∴ 0.8 mol of AgBr is produced from 1 x 0.8 / 1 = 0.8 mol of AgNO3.
Strength of AgNO3 = 3.5 M
Volume of AgNO3 required = Number of moles / strength
= 0.8 moles / 3.5
=0.229 L
