Achemical engineer must report the average volume of a certain pollutant produced by the plants under her supervision. here are the data she has been given by each plant: plant volume of pollutant macon 0.519 lallegheny 44.67 ldoheny 0.826 lwhat average volume should the chemical engineer report? be sure your answer has the correct number of significant digits.

The chemical engineer should report average volume of 15.34 L.

Explanation:

Volume of Macon = 0.519 L

Volume of Allegheny = 44.67 L

Volume of Doheny = 0.826 L

Average of the volume of the pollutants:

The rule apply for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

Here the 44.67  has two significant digit after decimal point.So the answer will be reported as in with 2 significant figures after decimal point.

The chemical engineer should report average volume of 15.34 L.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
