A pharmaceutical company wants to test the efficiency of its new drug production techniques so they run 3 shifts of production f
spayn [35]

The percentage yield of the  new production technique is 82.8%

<h3>What is the percentage yield?</h3>

Production is the procedure by which finished products are obtained form the raw materials. The production process involves the passing of raw materials through a certain procedure that involves the use of certain machines and equipment to give us the required products.

We are told in the question that there are three shifts;

Shift 1 produces 4562 grams

Shift 2 produces 5783 grams

Shift 3 produces 5247 grams

Average production from the three shifts = 4562 grams + 5783 grams +  5247 grams/3 = 5197 grams

The theoretical average yield is =  7000 grams + 7000 grams + 7000 grams/3 = 7000 grams

Now the percentage yield = actual yield/ theoretical yield * 100/1

percentage yield = 5197 grams/7000 grams * 100/1

percentage yield = 82.8%

Which of the following is a homogeneous mixture?
Gala2k [10]

Answer:

Water and applesauce are examples of a Homogeneous Mixture

Chicken Noodle Soup and Soil with Water would be examples of a Heterogeneous Mixture.

Explanation:

Homogeneous Mixtures are mixtures that are the same throughout, i.e. it's just one substance. A good example of this is a glass of water, this is because it is all one solution <u><em>without any other visible</em></u><u> </u><u><em>different parts</em></u><em> </em>that will settle if left alone for a while. The same applies to the applesauce, it is one type of a mixture with nothing else added to it.

Hetergeneous Mixtures on the other hand <u><em>are different substances </em></u>added together. The noodles, soup and chicken, three different substances in one mixture. The soil and water mixture also applies, two substances which separate if left alone.  

See http://chemistry.elmhurst.edu/vchembook/106Amixture.html#:~:text=A%20homogeneous%20mixture%20has%20the,gas%2C%20liquid%2C%20and%20solid. For more information.
