1. yes
2. yes (I've seen this come up on multiple tests I took and even though it doesn't explicitly state it in the rules, it's a good word to know just in case )
3. It's "Dose makes the poison." it's not really a saying, but it's something important to know about poison.
Tests will probably ask some broad questions about toxicology because, you know, it's called potions and poisons.

1. nonpoloar. carbon and oxygen have different electronegativities, so the oxygen will pull the electrons closer to itself. this makes it so the electrons are not shared equally.
2. a double dilution is when after each dilution you cut the concentration in half.
3. 1 Li3PO4 + 3 NaBr → 1 Na3PO4 + 3 LiBr

Sorry this took forever...anyways I think you're mostly right except forone and two I was thinking more along the lines of the specific kinds (like london dispersion, hydrogen bonds, metallic bonds, covalent bonds) but it was a poorly worded question and you might still be right.
Your turn!

Thanks for letting me know! I guess I'll go (enjoy the questions lol):

1. What does the "N" stand for in the mnemonic "NOTRECLUSE"? What is the purpose of this mnemonic?
2. Name the types of calcium supplements and the two types that are most commonly used.
3. NOEL and NOAEL are both measures of toxicity. What is the difference between these two measures?
4. Prior to Bunsen burners, what was the primary method of fuel for chemistry heating units, and what is this substance's chemical formula?
5. What species is A. piscivorus commonly mistaken for, and how does one identify which is which between the two?

Now ... chemistry (have fun w/stoich) problems!
1. A solution of cadmium phosphate is mixed with a solution of ammonium sulfide. What is the precipitate that will be formed in this chemical reaction? (hehehehehe)
2. Silicon nitride (Si3N4) is made by a combining Si and nitrogen gas (N2) at a high temperature. How much (in g) Si is needed to react with an excess of nitrogen gas to prepare 125 g of silicon nitride if the percent yield of the reaction is 95.0%?.
3. Consider the chemical equation for cellular respiration. What mass -- in grams -- of carbon dioxide forms in the reaction of 25 grams of glucose and 40 grams of oxygen?

1. What does the "N" stand for in the mnemonic "NOTRECLUSE"? What is the purpose of this mnemonic?
Numerous.
2. Name the types of calcium supplements and the two types that are most commonly used.
Calcium carbonate (OTC), and Calcium citrate
3. NOEL and NOAEL are both measures of toxicity. What is the difference between these two measures?
No-observed-adverse-effect level (NOAEL): The amount of the substance doesn't affect the organism badly. No-observed-effect level (NOEL): The amount of the substance doesn't affect the organism at all.
4. Prior to Bunsen burners, what was the primary method of fuel for chemistry heating units, and what is this substance's chemical formula?
I don't know this one
5. What species is A. piscivorus commonly mistaken for, and how does one identify which is which between the two?
The cottonmouth snake is often mistaken for the Northern Water Snake. The difference between them is that the cottonmouth only has one row of scales after the anal plate
