Differentiate between covalent and ionic bonds
Covalent Bonds: Two or more nonmetals that are combines with each other through the sharing of electrons "Sharing is Caring"
Ionic Bonds: A bonding between a metal and nonmetal where electrons are being donated from a metal to a nonmetal

Water has many properties. Please provide at least three properties and give an example for each property?
Some of the properties are:
1. Cohesion: Allows water molecules to stick together and form bubbles
2. Adhesion: Allows water molecules to stick to other surfaces
3. Surface Tension: Water molecules can resist forces applied to their surface (due to Cohesion)
4. Capillary Action: Allows for water to travel upwards and resisting the force of gravity (due adhesion and cohesion)
