Re: Compound names
My TA said that we'll be given the formulas from the compound names we see on the test. Apparently naming compounds and writing its formulas will be introduced to us later on in the quarter.

Re: Compound names
Hi all,
I agree with above, however, you should be aware of the basic naming rules including prefixes and suffixes. These are very important in your chemistry career, and is this is only a review of high school chemistry topics, don't be surprised if they show up on the test and something isn't provided.

My TA said that we do not need to know the names of the compounds yet, they will be given to us on the test
Re: Compound names
I don't think we have to know all the naming rules at the moment, but I think it would be useful to know some basics since they keep appearing in the homework:
If the compound is ionic, you add an "ide" to the end (e.g. NaCl is sodium chloride)
Useful Polyatomics: (NO3 nitrate, NO2 nitrite, ClO4 chlorate, SO4 sulfate, PO4 phosphate, CH3COO acetate)
Hope this helps.

Re: Compound names
I don't believe that we have to know all the compound's names but it definitely will be useful for not only this class but for future classes in the future.

Re: Compound names
We will be given the necessary compound names on tests, so no we do not have to memorize them.

Re: Compound names
Does anyone know what page in the book has the prefixes and suffixes and what they are?

Re: Compound names
Does anyone know how to determine what the formula for nitrous acid is? Are there rules that can help with this?

Re: Compound names
When determining the formula for nitrous acid, you look at the suffix of "nitrous", that being "-ous". This is a classification of an oxoacid that refers to the compound with fewer oxygen atoms (as opposed to "-ic" referring to a compound that has more oxygen atoms). Additionally, since it is an acid, there would be a proton attached to the molecule, coming at the front when referencing a formula. In the end, you end up with HNO2 being nitrous acid and HNO3 being nitric acid.
