<h2>Answer:</h2>
  • Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s).

<u>Moles Cu present</u> = 100g Cu x 1 mol Cu/63.55g

= 1.574moles Cu

<u>Mass of Ag produced</u> = 1.574mol Cu x 2mol Ag / 1mol Cu x 107.9g Ag/mol Ag

= 340.g Ag

15.50 g of NH4Cl reacts with an excess of AgNO3. In the reaction 35.50 g AgCl is produced. what is the theoretical yield of AgCl
Shkiper50 [21]

Answer:

41.56 g

Explanation:

Given data:

Mass of NH₄Cl = 15.50 g

Actual yield of AgCl = 35.50 g

Theoretical yield of AgCl = ?

Solution:

Chemical equation:

NH₄Cl  + AgNO₃      →     AgCl   + NH₄NO₃

Number of moles of NH₄Cl:

Number of moles = mass/ molar mass

Number of moles = 15.50 g/ 53.491 g/mol

Number of moles = 0.29 mol

Now we will compare the moles of NH₄Cl with   AgCl .

                     NH₄Cl            :               AgCl

                        1                  :                 1

                     0.29              :                0.29

Theoretical yield of AgCl:

Mass = number of moles × molar mass

Mass = 0.29 mol ×143.32 g/mol

Mass = 41.56 g
