4. Hydrogen Bonds are not as strong as covalent or ionic bonds. T F

5. An example of solute would be

a. Plant in a vase

b. Kool aid in water

c. Cream in a donut

4. TRUE

5. b). Kool aid in water

Explanation:

Ionic Bonds : These types of bonds are formed by complete transfer of electron from atom to other. Atom which give electron get positive Charge and which gains electrons get negative charge.

Strong electrostatic force between oppositively charged ions make these bonds very strong

Covalent Bond : These bonds are formed by sharing of electrons. The electron density of on atom is attracted towards the nucleus of other atom.

Covalent bonds are weaker than ionic bonds

Hydrogen Bonds : These bonds are formed by weak dipole-dipole interactions which occur when Hydrogen atom in a molecule is bonded to the highly electronegative atom.

These are very weak bonds, weaker than covalent, ionic bonds.

5.

Solute : In mixture (e. g Salt + water), the substance that is present in less quantity is called solute (Salt).

Kool Aid : Powder Substance that is added in water / liquids to make flavoured soft drinks.

We, add small amount of Powder in large quantity of water. So Kool Aid is the solute
