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 500 grams of zinc and 1500 grams of silver nitrate will the make enough silver to fill the order

Answer 1

Answer:

Yes. Since they have more than the required reactants.

Explanation:

Zinc reduces silver nitrate to silver metal according to the following equation.

2AgNO₃ + Zn → 2Ag + Zn(NO₃)₂

From the equation 2 moles of AgNO₃ produce 2 moles of silver.

If we consider the zinc to be used number of moles=mass/RAM

RAM of zinc =65.38

No. of moles=500/65.38

=7.6476moles

To produce 800 grams of silver they require:

800/107.868 moles=7.4165 moles of silver nitrate since the ratio of silver nitrate to silver produced is 1:1

The number of moles of silver nitrate available=1500/169.872

=8.83 moles.

As the amount of reactants available is more than the required the company will make it in producing the 800 grams of silver required.
