Question

A chemical company makes pure silver by reacting silver nitrate with zinc. The company needs to make 800 grams of pure silver for a client. They have 300 grams of zinc and 600 grams of silver nitrate. Will they be able to make enough silver to fill the order?

Answer 1

The reaction between zinc and silver nitrate is...

Moles of Zn = m /M = 599 /65 = 9.2 mol
Moles of AgNO3 = m /M = 1500 /169 = 8.87 mol

Silver nitrate is reacting completely to give silver. Thus, moles of Silver nitrate is equivalent to silver = 8.87

For mass of silver produced
m /M = 8.87 = m /107
m = 949.24 g

Hence, the given quantity of reactants are sufficient to produce 800 g of silver as the amount of silver produced is 949.24 g.

Answer 2

Answer:

yes with left over silver
