Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Answer:
Nickel (Ni) is most likely to form more than one kind of positively charged ion as it is a transition metal and all of the ther metals have a fixed ion charge.
Na becomes Na+
Ba becomes Ba +2
Mg becomes Mg+2

Answer:
2.45Joules
Explanation:
since kinetic energy is K.E.=1/2m
lost in potential energy is gain of kinetic energy
mgh=1/2mv^2
9.8*2*0.5=v^2
=9.8
v=
=3.13m/s
now k.e. = 0.5*m* =0.5*0.5*9.8 =2.45J
D.) a transformation of light energy into chemical energy
Compounds. They both have more than one element in them
