For the Fructose structure, how come they have hydroxy- instead of -ol for the OH's? I thought that for -oxy, it was for ethers while OH's stood for alcohols/

For the first part of the question, how do we know that n=4? Do we find it through the given equation or do we have to delve deeper?

For week 8 and 9 of Professor Lavelle's Lecture, we've been going on for the positions of compounds such as staggered, eclipsed, etc. What type of questions would be asked as an example?

Since we got our workbooks back, I was wondering how for #5 can we determine what order the reaction based on the information. Do we have to know based on the details of the experiment or do we have to look at the units?

I'm still a little confused on how one can find the half life from just looking at a graph and using the plots/data. I think I got a lot of concepts jumbled around in my head, so can anyone give a brief overview on how to do it? Thanks!

How come for bond enthalpies, we have to do the sum of reactants minus the sum or products and not the other way around like how we calculate the sum of delta G and delta H?

How would you do the partial pressure in this question? Bromine chloride, bromine, and chlorine gases have reached equilibrium in a container at 500 K according to the reaction, 2 BrCl(g) <--> Br2(g) + Cl2(g). Equilibrium partial pressures are 1.08 bar BrCl, 4.9 bar Br2, and 7.6 bar Cl2. Half the Br...

If we want to post a video about Chemistry, what are the guidelines and where do we send it too?

Is there a way that we can know how many resonance structures a compound has or do we have to exhaust every possibility every time?

After hearing Lavelle's lecture about some elements having an exception to the rule of filling up every energy level (e.g. Chromium and Copper), I was wondering if there was a way to know about these exceptions. It seems pretty random on the table, but is there a way to know if the element is going ...

Hey! To be honest, I don't know where to even begin with this problem. If anyone could help me that would be nice!

You need to prepare 510. g of an aqueous solution containing 5.45% KNO3 by mass. Describe how you would prepare the solution and what mass of each component you would use.
