Homework 3.39

Postby camrynpatterson3C » Tue Nov 07, 2017 7:45 pm

This question asks to write the Lewis Structures for ammonium chloride, potassium phosphide, and sodium hypochlorite, but it doesn't give their formulas. Are we supposed to know how to write these? Like ammonium chloride is NH4Cl, etc. Or is he always going to give us their formulas to use?

I'm pretty sure he is going to give us the chemical formulas during the exam. However, he might expect us to know the formulas for common compounds such as water and carbon dioxide.

Yeah, since he hasn't gone over nomenclature in class we aren't expected to know it, so the formulas will be given on the exam.

For this test he is going to give us the formula with the names, so you don't need to know it for now. However, in order to figure this out, you would need to a) know what all the prefixes and suffixes mean for the naming part and b) you would need to know the charges from the periodic table (or just have the charges memorized for the molecules).
