1. water is a(n) ▲ ____ compound because it is only

made up of ▲ __ and ▲ __ and not
● ____.

1. the chemical formula of water is ▲ ____
2. the water molecule is formed by ● __ __

bonds.

1. unequal sharing of electrons makes water a ● ____

molecule.

1. the oxygen end is slightly ● ____ and the hydrogen

ends are slightly ■ ____.

1. due to waters ● __ it can form ■ __

bonds with the neighboring water molecules.

Explanation:

1. Water is an inorganic compound as it lacks carbon. It's made of hydrogen and oxygen.
2. The chemical formula of water is \(H_2O\).
3. Water molecule forms via covalent bonds (sharing electrons).
4. Unequal electron - sharing makes it polar.
5. Oxygen (more electronegative) is slightly negative; hydrogen is slightly positive.
6. Polarity allows hydrogen bonds (attraction between polar molecules).

Answer:

1. inorganic, hydrogen, oxygen, carbon
2. \(H_2O\)
3. covalent
4. polar
5. negative, positive
6. polarity, hydrogen
