Hi, how wld u know which had stronger hydrogen bonding, something like NH3 or something like H2O?
Thanks

The ultimate goal while working with hydrogen is to be able to run an engine with the hydrogen produced by that same engine. It is possible. It has been done. You won't accomplish that by reading this material. But maybe this can be your starting point...

To offset that, Hydrogen is more easily....
Now when running on Hydrogen alone, there is less power if nothing else takes up about 4% of the combustion chamber, whereas Hydrogen will need about 20% of the space.

I am not talking overunity, but there is always a chance that hydrogen can be created cheaply enough to be used as a fuel, once storage and safety concerns are addressed.

10 points! What is a "picture" of the current atomic model for a Hydrogen? (It's an hydrogen atom)
http://farm6.staticflickr.com/5275/69699…

If none, what's acceptable then?
Also, I've seen this, which is called "Silicon covalent...

Answer Snippets (Read the full thread at yahoo):
OK
1) The "picture" of hydrogen is 1, because of the electron cloud model
2) The "balls" are silicon atoms and the "shafts" are the bonds between those atoms, the picture is trying to show and the sticks/shafts are the (covalent) bonds....

Hallo all,
I have the following question: how come intramolecular bonds are stronger (more favored) then intermolecular bonds in DNA.
I am working with a scorpion probe and the principle of this probe is that it can bind intramoleculary with complementary...

How far from an intramolecular species?
A large part of the bond strength is that you have removed?
A large part of the bond strength is that you have removed a portion of the entropy by fixing.

Hi all,
I was just trying to find out the reaction or place were carbon can have 5 bonds.
I have seen before were carbon had 5 bonds to it, it was an intermediate to some reaction, long time ago,
I was wondering if anybody had any ideas as to what reaction...

Which compound contains both ionic and covalent bonds? 10 points for best answers!!? 1) HBr
2) CBr4
3) NaBr
4) NaOH
Please explain why as well and how you arrived to the answer, I don't understand this, thank you so much!!!!

Ionic bond between the Na^+ and the OH.
It would be number one because both Hydrogen and Bromine are connected by a single valence election
Covalent bond between the O and the H of the hydroxide.
