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

or 4 hours each and collect the product at the end of each shift. Their chemical engineers predict a maximum of 7000 grams of product can be created each shift.
Shift one produces 4562 grams.
Shift two produces 5783 grams.
Shift three produces 5247 grams.

What is the average percent yield for this new production technique?
A. 82.61%
B. 51.97%

What is the answer please
xeze [42]

Answer:

Selenium

Explanation:

Oxygen is present in the group sixteen.

This group consist of oxygen, sulfur, selenium, tellurium and polonium.

All of these have same number of valance electrons thus they show similar properties.

From the given list of elements only selenium is belong to oxygen family thus it has properties similar to the oxygen.

Electronic configuration of oxygen:

O = [He] 2s² 2p⁴

Electronic configuration of selenium:

Se = [Ar] 3d¹⁰ 4s² 4p⁴

While aluminium, boron and phosphorus are belongs to other groups that's why their properties are not similar to the phosphorus.

phosphorus is present in group 15.

Boron and aluminium are present in group 13.
