The balanced reaction is:

AgNO3 + NaCl = NaNO3 + AgCl

<span>We are given the amount of silver nitrate to react with sodium chloride. This will be our starting point.</span>

15.0 mol AgNO3 (1 mol AgCl / 1 mol AgNO3 ) =15.0 mol AgCl

The amount of moles produced is the same with the amount of the given reactant since they only one is to one ratio.

Answer :

Oxidation number or oxidation state : It represent the number of electrons lost or gained by the atoms of an element in a compound.

Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.

Rules for Oxidation Numbers are :

The oxidation number of a free element is always zero.
The oxidation number of a monatomic ion equals the charge of the ion.
The oxidation number of Hydrogen (H) is +1, but it is -1 in when combined with less electronegative elements.
The oxidation number of oxygen (O) in compounds is usually -2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

Now we have to determine the oxidation state of the elements in the compound.

(a) $H_2SO_4$
