1. Elements that make up water is one oxygen and two hydrogen atoms.
2. Water is a molecule that contains one oxygen and two hydrogen atoms connected by covalent bonds. Therefore, a covalent compound.
3. Water is in three states: liquid, solid, and invisible (water vapor). Clouds are accumulations of water droplets. Because it can exisit in three states, the shape of water is hard to describe. Liquid water moves and such but tends to fill up the container it is in and is flat on top. When water is solid it is in the form of ice which can be any shape that it is forming to. And when water is invisible we do not know what shape it is in but I believe it is all around us in the sky and in the clouds.
4. The hydrogen bond between water molecules is the reason behind two of water's unique properties: cohesion and adhesion. Cohesion refers to the fact that water sticks to itself very easily and this is because of the hydrogen bonds that help make water molecules stick to each other.
5. Salt and sugar are both polar, like water, so they dissolve very well in it. Substances, like oil, that do not dissolve in water are hydrophobic.
