Astudent measures the volume of a liquid in a graduated cylinder of 250 ml capacity, and finds the volume of the liquid to be 200 ml. the student transfers the liquid to a graduated cylinder with a capacity of 500 ml. what is the volume of the liquid in the 500 ml cylinder?

a. unknown

b. 100 ml

c. 200 ml

d. 500 ml

Option C = 200 mL

Explanation:

The volume of liquid remain same because students just transfer the liquid from the graduated cylinder with the capacity 250 mL to the graduated cylinder having the capacity of 500 mL. The volume of the liquid will remain same either it is in the large graduated cylinder or in a small graduated cylinder.

"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."
