Yes, it is water.
it can
To be a true solution seawater must be filtered.
Because seawater has particles in it that can be filtered whereas distilled water is pure
No, water is a compound of hydrogen and oxygen. And filtered sea water would still have many other impurity's in it as well
Filtered seawater is a mixture of dissolved salts, minerals, and organic matter that is left behind after removing larger particles and impurities from seawater. It contains a high concentration of sodium chloride (table salt) and various other ions that make it different from freshwater.

Seawater is water with salt in it
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
FeO is not a nonmetal; it is a compound composed of iron (a metal) and oxygen (a nonmetal).
