Answer:
1. Element - a substance that is made from only one type of atom
An element is made up of only one type of atoms and known for its unique properties than other elements.
2. Heterogeneous - composed of dissimilar parts which can be separated easily and which are unevenly distributed in the mixture
3.Homogenous - even distribution of parts throughout the whole mixture; not easily separated into individual components.
4. Product - the substance created as a result of a chemical reaction
Products are the final substance that created as a result of a chemical reaction.
5. Reactant - one of the starting substances (ingredients) that is involved in a chemical reaction
Reactants are the starting substance that takes part in a chemical reaction.
6. Solute - the substance that is being dissolved.
A Solute is a substance that is being dissolved in the solvent to make a solution.
7. Solvent - the substance that does the dissolving
A solvent is the medium in which the solute is being dissolved to make the solution.
Well that depends on the central atom. Remember each bond indicates another electron that is being shared with the central atom.
So CO4, carbon would be your central atom, with the 4 oxygen around it. There would be no double bonds because carbon only requires the 4 electrons provided by the oxygens, because of its location on the periodic table.
Nitrogen on the other hand is different. It's found in group 5 (5V) and has 5 valence electrons on its outer shell. So NO4 would have a central Nitrogen atom, with 3 oxygens providing a single bond, and one oxygen providing a double bond, because Nitrogen needs 5 electrons!
We learned it like this, the atom brought x amount of electrons to the party, x representing the valence electrons, and must leave with x electrons. It's silly but it works!
I hope I was able to help and clarify a few things up!

Answer:
Kinetic energy because it has motion, Potential energy bc there is still more distance to fall and heat energy bc there is heat from friction.
Explanation:
C. 96.82 kPa because to find the amount of pressure the air is causing you need to subtract the amount of pressure the water vapor is causing because the only two gasses making up the air in the pool area are air and water vapor.
