Therefore, there are 354 grams of water in the solution.
Oxygen because it is one the table of elements and none of the others are.
A polar covalent bond is a covalent bond in
which the atoms have an unequal attraction for
electrons and so the sharing is unequal. ... The
atom with the greater electronegativity acquires
a partial negative charge, while the atom with
the lesser electronegativity acquires a partial
positive charge.
here you go
