Naming Molecules and Molecular Formulas on Midterm?

[Jessica Tam 3H]

Hi,
I was wondering if we would be expected to know the molecular formulas by the name and vice versa or will they be given on the exam like in textbook problem L.39. For example, we have to derive the empirical formula then name it tin(iv) oxide. If we do need to know it for the exam, how do we know it is tin(iv)?

And for M.7, how do we get the molecular formula for boron oxide or magnesium oxide?

I do think he might reference compounds by name and we should know their formulas-- I think it's mostly true for polyatomic ions and their formulas because those show up fairly often and might be good to know.

If I remember correctly, my TA said she wasn't totally sure but he's likely going to give us whatever it is we need that we didn't explicitly learn in lecture. So, I'M guessing we would only need to know common molecular formulas glucose, carbon dioxide, water, etc. I MAY be wrong though.

I know it's past the midterm, but as a general rule of thumb, it's good to know a few common ones. My go-to's are usually nitrate and nitrite.

Although it's past the midterm, a good rule of thumb is just to know the common ones. If the problem calls for knowing the elements in the empirical or molecular formula, your better off knowing the common ones. We'll eventually learn how to identify and recognize the formulas by name.

for the future exams, I would say learn maybe the basic and well known polyatomic ions. I learned some ions based on what was expected of us to know on the textbook problems that were assigned to us in the syllabus, such as nitrate or sulfate
