How can you improve the percent yield of copper in this lab? Check all possible strategies that will help you do so.
Paladinen [302]

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

Which of the following statements is correct about the force of gravity between two objects?
SVETLANKA909090 [29]

Answer: D

Explanation:

Shape and temperature have nothing to do with gravity. You could take a circle block and a square block and put it on the ground and they will stay there. Gravity is not weaker when objects are closer together because of Newtons law of gravitation.
