What does that mean about the densities of the phases of water?
Density involves the amount of a material in a certain
volume. When a material changes phases, it changes
in density in a predictable way as the amount of
material stays the same but the molecules get farther
apart or closer together. Water has solid and liquid
states that do not follow these predictions of density in
the phases of matter
O The solid state is the most dense, followed by the
liquid state, then the gas state.
O The solid state is more dense than the liquid state
The liquid state is more dense than the solid state
The gas state is the most dense, followed by the
liquid state, then the solid state

"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."

b is the correct answer

mark me brainliest and hope this
