You are on an island and need freshwater to drink. Which process could you use to separate the salt from ocean water and provide freshwater for
drinking?
O A. Distillation
B. Chromatography
C. Filtering
O D. Freezing

A

Explanation:

The reason it is distillation is due to the fact that we can use distillation to heat the ocean water. As water has a lower boiling point than the salt solution, it evaporates and the salt stays behind.

"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."
