Jelena is studying the properties of water. She finds that a sample of 100 mL of distilled water boils at 100°C and has a density of 1 g/cm3. What will Jelena most likely find to be true about a sample of 200 mL of distilled water?
OA. It will boil at 100°C and have a density of 2 g/cm3
ОВ.
It will boil at 200°C and have a density of 2 g/cm3
OC. It will boil at 100°C and have a density of 1 g/cm3.

"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."
