Assume that the scientist set up an identical respiration chamber, except that in this setup she placed a mouse that had been exercising on a hamster wheel. then, the scientist measured the amount of co2 given off by both mice at the end of 15 minutes. predict which setup produced the most co2. explain your answer.

Explanation:

Mouse undergoing exercise will produce more Carbon Dioxide because exercising would require more energy inducing more cellular respiration and producing more carbon dioxide.

Hence the setup in which the mouse exercises will produce more CO2 and the reason is explained above.

"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."
