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.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants
