Very well done.

9. Urushiol is active toxin in poison ivy & oak. Approximately 15-25% of humans have no reaction to it, therefore 300-500 people exposed to it will have no reaction.

10. Prolonged exposure to ammonia or chlorine decreases your ability to detect their odors, which can lead to damage.

Bonus!

What popular food has urushiol in its skin?

You'd have... uh... thirty cents?

Explain how to separate the components of a salt water and sand mixture.

Anion = negative ion and cation = positive ion
steps:
1. mix to dissolve the salt into the water
2. strain the mixture through filter paper to separate the sand from the salt and water
3. heat the saltwater to evaporate out the water
my events tend to deal with really big or small things ..
so now i do fermi : ^)

I minus well just post a few more questions.

1. What is the difference between intermolecular forces and intramolecular forces?
2. Is hydrogen bonding intermolecular or intramolecular?
3. What is atomic radius and how is it shown in the periodic table? (Kind of vague, I can explain further if needed)
4. What is London Dispersion forces and how do they compare to other chemical bonds? (basically, is it stronger or weaker than other bonds)

Answers
1. Intermolecular forces are those between molecules, and intramolecular forces are those within a molecule.
2. Hydrogen bonding is intramolecular.
3. Atomic radius is the radius of a atom. {I can elaborate if I need to.} Atomic radius increases to the left and to the bottom. {Is that what you wanted?}
4. London Dispersion forces are generally weaker than other chemical bonds.
