I'm just wondering if someone can point me in the right direction here.. or maybe I'm just crazy lol. I'm a big coffee drinker. When I go out, I usually grab a coffee and walk around with it in hand. (mall's, convenience stores, book stores, subways and buses etc...) and as expected there is...

silver nitrate + water ?? / Br in water? Hey guys, thanks guys. got my answer!

there are a million answers to this, but what comes to mind as some of the biggest ones? I have to research a few of these, preferably something has has improved existing products to make them better for our health/the environment. One big one is unleaded instead of leaded gasoline. Any...

I would still think that the hydrogen interactions are stronger, but again I don't know what the strength of bond or the strength of the molecular interaction has to to with it... i think that's my main problem,.. I'm not understanding the concept of the vortex and what its actually doing to the...

hmm well hopefully someone can explain this to me... otherwise I'll just have to make something up :frown: ,, lab is due tomorrow. I just don't think its viscosity, because we haven't learned it, and I'm not expected to know that... its all about the intermolocular bonding

yeah, but we haven't learned anything about viscosity.. I'm being asked to explain what happens in terms of intermolecular bonding :frown: hmmmm...is there a connection between viscosity and intermolecular bonding? or are they totally seperate?

I have done a similar experiment, and I still don't quite get it... I understand that hydrogen bonds are the strongest.. but what does that have to do with depth of the vortex or the amount of time it lasts? are we breaking bonds here? Why does the strongest bond have the deepest vortex...

ahh ok, thanks for the quick response ... I was trying to come up with something that would give me a precise answer.. but i guess that's not the most efficient way to solve it. :smile: So basically, just pick the lines of an imaginary cube, calculate the volume.. Count the amount of...

Ok I am trying to show the packing efficiency for 3 different types of packing. 1) Hexagonal closest packing (efficiency = 74%) 2) Cubic closest packing - (efficiency = 74%) 3) Body-centered - (efficiency = 68%) I know the efficiency values because they are in my textbook and all over...

yes that is 0.5 cm

EDIT: Ok something is wrong here.. so I'm doing the experiment again. I'll post the results as soon as I'm done

Hello, I have done an experiment and I am having trouble explaining why certain things happen. The topic is intermolecular bonding. I used three liquids, each is composed of different types of bonds. liquid 1) Hydrogen bond liquid 2) bonding due to dipole forces liguid 3) bonding due to...

Ionic equation help Hello, I was wondering if someone could help me work through an Ionic equation question step by step. (Its been a few years since I've done this stuff, and I think if I work through an example It'll come back) This is a question from my textbook. I have the answer...

Hello all, I'm re-learning chemistry on my own and have a quick question that I can't find the answer to in my book. Its about writing formulas. For example, aluminum chloride. I know that Al has a valence number of +3, and I know that Cl has a valence number of -1. So applying the...
