When copper wire is placed into a silver nitrate solution silver crystals and copper(ii) nitrate solution form. write a balanced chemical equation. of a 20g sample of copper is used, determine the theoretical yield of silver?

A. The balanced equation for the reaction between Cu and AgNO3 is given below:

Cu + 2AgNO3 —> Cu(NO3)2 + 2Ag

B. 68.03g

Explanation:

A. Step 1:

The equation for the reaction between Copper (Cu) and silver nitrate AgNO3. This is illustrated below:

Cu + AgNO3 —> Cu(NO3)2 + Ag

A. Step 2:

Balancing the equation.

Cu + AgNO3 —> Cu(NO3)2 + Ag

The above equation can be balanced as follow:

There are 2 atoms of NO3 on the right side and 1 atom on the left. It can be balance by putting 2 in front of AgNO3 as shown below:

Cu + 2AgNO3 —> Cu(NO3)2 + Ag

There are 2 atoms of Ag on the left side and 1 atom on the right. It can be balance by putting 2 in front of Ag as shown below:

Cu + 2AgNO3 —> Cu(NO3)2 + 2Ag

Now the equation is balanced.

B. Step 1:

Determination of the mass Cu that reacted and the mass of Ag produced from the balanced equation. This is shown below:

Cu + 2AgNO3 —> Cu(NO3)2 + 2Ag

Molar Mass of Cu = 63.5g/mol

Molar Mass of Ag = 108g/mol.

Mass of Ag from the balanced equation = 2 x 108 = 216g

From the balanced equation above,

63.5g of Cu reacted.

216g of Ag is produced.

B. Step 2:

Determination of the theoretical yield of Ag.

The theoretical yield of Ag can be obtained as follow:

From the balanced equation above,

63.5g of Cu reacted to produce 216g of Ag.

Therefore, 20g of Cu will react to produce = (20x216)/63.5 = 68.03g of Ag.

Therefore, the theoretical yield of Ag is 68.03g

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
