Which of these best explains why the hydrogen adams in a water molecule are attracted to cl- ions in sodium chloride (nacl)? the hydrogen atoms have +one charges the hydrogen atoms share electrons equally with the oxygen atom the hydrogen atoms have partial positive charges the hydrogen adams form covalent bonds with chloride ions

-

The hydrogen atoms have partial positive charges

Explanation:-

In a water molecule there are twp atoms hydrogen and oxygen.

Oxygen has more electronegativity than hydrogen. So the electrons in the bond between Oxygen and hydrogen are more towards oxygen. So hydrogen has a partial positive charge.

The Cl- has negative charge. Positive charge is attracted by negative charge.

Due to this hydrogen atoms in a water molecule are attracted to Cl- ions in sodium chloride (NaCl).

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
