A student dissolved 3.50g of copper (II) nitrate in water and mixed it with a solution of sodium carbonate. The student recovered 1.89g of copper carbonate precipitate. If the theoretical yield is 2.35g, what is the percent yield

If the theoretical yield is 2.35g then the percent yield is 80.4%

Explanation:

Given: Actual yield = 1.89 g

Theoretical yield = 2.35 g

Formula used to calculate the percentage yield is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that if the theoretical yield is 2.35g then the percent yield is 80.4%

i think so it’s will be b yes i believe its

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
