I am learning about Natural vs. Synthetic And I have to answers some questions which she didn't give no resources
Questions:
2) What is the importance to humans? (Why do humans use/make it?)

3) What natural resources are used to make the synthetic material?

4) What are the atomic structures of the reactants and the synthetic product?

5) How is the synthetic material made? (What chemical process(es) are used to create the product?)

6) What are the negative and positive impacts/effects of making and using the synthetic
material, compared to making and/or using a more natural material with a similar function?

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
