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

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
