Quantum mechanics makes me want to cry. Does anyone have any suggestions on good books that really break things down. I believe this is one of the few subjects that i would willingly buy a book with dummy in the title such as "quantum mechanics for dummies." Unfortunately there isn't a book out there with this title. In fact i haven't found any books that attempt to really break quantum mechanics down. I have Griffiths, a dover book on problems in quantum mechanics, and i've read over the Schaum's outline. Does anyone have any suggestions? thanx. -justin

What properties would be different (other than the structure itself) of let's say, propan-1-ol and propan-2-ol?

a chemical god?? is it possible?? i just have this thought about a god being completely chemical &biological origin. what is god ?? god is a source of life what keeps us alive? the earth and its elements what are we ? biological if u see all these qs and as it could add up to something.

Yesterday, i was reading about how electrons have different orbitals, within shells and the shape of the orbitals. I quickly realises that the orbitals took a spherical shape. My question is: What causes the electrons to move in this orbital, and stay in there most of the time? Is it because electrons are though to be spherical themselves? Is it because protons exert a force, possibly an even force, like that of a magnetic field? Or is it something to do with the waves of electrons? Can anyone answer this for me?

Well can some kind person explain how sub orbitals hybridise and the explaination behind it, and how the suborbitals take on new shapes to allow for this.

How do I determine concentration in .0008496 mols of AgCl4?

Would anyone help solve my questions? 1.Are all polyatomic ions have covalent bonds(the electrostatic forces between the shared electrons and bonded atoms)? 2.Are they covalent compound? 3.Like ammonium(NH4), how does it exist? 4.Why aren't they have 0 charged? 5.How to estimate the charge of them?

I just performed an analytical chem lab yesterday and it was about gravimetric analysis of chloride, during the lab, the TA gave me a question that puzzled me, "if a solution contains both I- and Cl- at about 0.1M, can we determine the amount of Cl- and I- independently by using gravimetric analysis?"... my guess is no, but I don't know how to explain this, can someone please provide an explanation to this question? thank you very much!

undefined Hey everybody, mine my name A.J. and I am a student, I need help on a project. Details: 2 sodas are put in an aquarium (filled with regular water (H20)) the sodas are: diet coke; and regular coca cola. the diet floats while the coca-cola sinks.. question is why? i have a few theories, but i like to keep them to myself to prevent looking stuiped thx to anyone who can help me.

hi i am doing an experiment on testing strength of glues i do this by putting 2 block of wood glued together and screwed on either side are 2 hooks. i hang this onto another hook which is on a wall and with the remaining hook i put weight on it till the blocks of wood separates...i do this in 4 different condition for each brand of glue, cold, hot, wet and room temperature. what is my control/s? and explained why what is my experimental variables and the variables i need to keep the same? identified variables and units that will be used to collect the data... please help quickly!!! thank so much

Hi, During my courses I recently performed a labtest in which this reaction occured after heating. There was MnO2 present too (to speed up the reaction) 2KCLO3 -> 3O2+2KCL Now I heard that you can use (powder)sugar in stead of MNO2 as a katalysator. Can anybody explain me why or how sugar will speed up this reaction?

does anyone know what those throw downs you buy in shop are made of?they are a white crystal substance. thanx

School is almost up for me. I'm a sophomore in high school, by the way. I took my first chemistry class the last half of the year and loved it. My teacher was great. She knew so much about chemistry and knew how to impart it perfectly. Now, my question is I want to continue to explore chemistry over the summer. What should I do? That is what cool experiments do you know that can be done with easily attainable supplies(i.e. local hardware store) at my house? Also, what are some of the best sites to learn chemistry off of? Thanks.

ok, i need a website or program that can give potentual substences given certin info..i got things like boiling point, freezing point, flambility, solubility, density, and a few other random facts... and thensomethign else i can compare a color spectrum that i got to other common ones...PLEASE lemme know if any onehere knows of anything..i really need something! im on a trip, and when i get back i need to have this paper finished, i got about 6/20 pages done, and i really need this!!(sorry if this is the incorrect place to post this, im just an innocent 9th grader!!!)

2689.1 I can't seem to find the answers to these questions in my Chem book. If someone can help me, I'll really appreciate it. 1. "When chemical compounds form, valence electribs are those that may be ______" 2. "The number of valence electrons in Group 1 _______" 3. "The number of valence electrons in Group 17 element is _______" 4. "The number of valence electrons in Group 2 element is ______" 5. "The elements in Group 1 are also known as the ______"

Could it be? This may tax your mind, to grasp and collate all these concepts that I’m about to lay on you. I know that these thoughts taxed mine, when they first came to my mind. I'm not sure how long ago it was when I first contemplated this, but I know that it was quite a few years. Then it came back to me the other night, while watching a showing of Nova, about the new string theory, the unified field theory, and other stuff. Could it be, that the Unified Field Theory is right under our noses, so close that we cannot see it? Might gravity, electro magnetic, and the magnetic forces, all run off the same “fuel”, the fuel of opposites attracts. We all know that the no…

Help with this question would be greatly appreciated, i just cant seem to get the answer, estimate the percentage of empty space in gaseous argon, given that the radis of an argon aton is 192pm (1.92x10-10m)

1) 1 Cu2O(s)+ (1/2)O2(g) -> 2CuO(s) Change in H = -144 kj 2 Cu2O(s) -> Cu(s) + CuO(s) Change in H = +11 Calculate the standard enthalpy of formation of CuO This is what i did, i reversed the 2nd equation so i get Cu(s) + CuO(s) -> Cu2O(s) by applying hess law, and Change in H becomes -11, then i added both equation 1 and 2 and got Cu(s)+(1/2)O2 -> CuO(s) after balancing, and the standard enthalpy becomes -144 kj - 11 kj which equals -155 kj.. Did i do this problem correctly? The following questions i got wrong and i have no idea why... 1) Calculate the S*net for the following reaction, Given the S* vales: Na(s)=51.4 e.u, H20 (l) = 69…

I know that Kw is equilibrium constant for water.. but what is Ka and Kb? I Is Ka equilibrium constant for acid and Kb equilibrium constant for Kb? If so how can u find those?? For example..here is an equation Kw = [OH-][H+] = 1e-14 What is the Ka and the Kb? Someone told me that Kw=Ka*Kb...is that true?

delta Hideal- delta Hreal = ? < 0, > 0, = 0 ? and, delta Sideal- delta Sreal = ? < 0, > 0, = 0 ? Also, if someone could PM about how to get math symbols in revised forum, it would help. Thanks.

Hi, i am a 3rd year in General Chemistry, freshmen at a university, and i have a few problems that i've encountered along the way. These questions has been bugging me for a long time now and i really hope someone can fill in the holes and gaps in for me..anyways here they are 1) Lets say you have a .00035 L volume of .25 M Pb(NO2). What are the moles of Pb2+? This is my guess on how to do this. Since molarity = moles/volume...molarity of pb2+ = moles of pb2+/.00035 But how would i know what the molarity of Pb2+ is?? Can i just use .25 M Pb(N02) instead? Is it the same thing or am i missing something here 2) Lets say you put a test tube which in a hot bat…

hello everyone, I was trying to do a practice exam last night and come upon this question about rate determining step, I'm confused on how you can tell which step is the rate determining step from a table that gives you rates and concentrations for individual reactant, here's the question: consider the following data for the reaction: H2O2 + 3I + 2H -> I3 + 2H2O [H2O2] [H] Rate I. 0.100M 5.00E-3M 1.00E-2M 0.137M/s II. 0.100M 1.00E-2M 1.00E-2M 0.268M/s III. 0.200M 1.00E-2M 1.00E-2M 0.542M/s IV. 0.400M 1.00E-3M …

I'm having problems with questions like this... I'm sure how to go about solving it... an explaination to the working out would help. thanks Calculate the volume of gas occupied by 3.6426 g of nitrogen at 45.00oC and 101.3 kPa given that value of the gas constant, R, is 8.314 J/K.mol.
