Measure reactants precisely.

Stir to help the reaction take place.

Wait patiently until the reaction completes.

Make sure to recover as much copper as possible.

Explanation:

Anything that increases the rate of this reaction will improve the yield of copper production.

The rate of reaction is usually a factor of how the concentration of reactants and products changes with time.

Some of the factors that affects the rate of a reaction are:

  • Nature of reactants
  • concentration or pressure if gases
  • temperature
  • presence of catalysts
  • degree of mixing

In this reaction:

  • to ensure we have the maximum amount of copper produced, measure out the exact/accurate amount of reactants stated
  • make sure you stir the reactants to ensure they mix and combine.
  • ensure you are not too much in haste. Wait for the reaction to go into completion.
  • recover as much copper as possible

If the concentration of the stock (provided) Cu(NH3)42 was 0.041 M, what concentration will the Cu2 be in beaker?
kodGreya [7K]

Answer:

[Cu^{2+}]=0.041 M

Explanation:

Hello!

In this case, since the molarity of a solution is defined in terms of the moles of the solute and the volume of solution, given that the concentration of Cu(NH₃)₄²⁺ is 0.041 M, and there is only one copper atom per Cu(NH₃)₄²⁺ ion, we can compute the concentration of Cu²⁺ as shown below:

[Cu^{2+}]=0.041\frac{molCu(NH_3)_4^{2+}}{L}*\frac{1molCu^{2+}}{1molCu(NH_3)_4^{2+}} =0.041 \frac{molCu(NH_3)_4^{2+}}{L}

[Cu^{2+}]=0.041 M

Best regards!

Bacteria reproduce using
nadya68 [22]

Answer:

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). ... Each daughter cell is a clone of the parent cell.

If 0.200 moles of NO are produced, how many moles of copper (I) nitrate produced?
Nadusha1986 [10]
Al(NO3)3 + 3KOH -------> 3KNO3 + Al(OH)3

50 ml * .2 moles/ liter = .01 Moles of Al(NO3)3

200 ml * .1 moles/liter = .02 Moles of KOH

Since the ratio between the two reactants according to the chemical equation is 1:3, we would need .03 moles of one to fully react with .01 moles of the other. Since we don't, only 1/150 mole of the first reactant will react with the .02 moles of the second reactant. This will produce .02 moles of KNO3 as well as .01 moles of Al(OH)3

.02 moles KNO3 = .02(48 grams + 14 grams + 40 grams) = .02(102 grams) = 2.04 grams
