I've been searching far and wide and simply cannot find any info on the BOND ENERGY of a Fe- N coordinate-covalent bond, like that found in the heme group of haemoglobin.
it looks like this:
N -- Fe2+ -- N
I was wondering if anyone knew a site that would tell me the properties of haemoglobin such as its boiling point, melting point, etc.. I can't seem to find any. I am doing a project on the "heme group" and I need to find properties such as weight, bp, ml, etc for heme group...
Just to add, the purpose of this question is to understand the shape of the heme group molecule using bonding theory...I have to write about all th ebond angles and such...whew...so I guess I need to understand any resonant structures and lone pairs, etc...
I am confused as to the structure of a heme molecule. A picture of it is shown here:
I understand the heme group is largely a porphyrin molecule. The 4 Nitrogens are coordinate-covalently bound to the central Iron atom. The...
We are doing a physics lab where we lift a pendulum to a certain height, let go of it, and the pendulum strikes a physics cart on a track. A lightgate then measures the velocity of the cart.
We need to figure out the speed of the cart given the distance the pendulum is raised by...
Scott: This is pretty easy!
The only thing u do is make sure both bormal vectors are not scalar multiples of eachother..... in other words
if P1 = Ax+By+Cz+D
and P2 = Wx + Xy +Yz +Z
then to intesect in a line..... [A,B,C] canot equal k[W,X,Y] k is any num
I'm sorry....I don't quite understand this phrasing...could you repeat it please. Ok I know the first number in the combination can be any of the numbers 0-59. Then the second number in the combination can also be any of the 60 digits. However, the 3rd number needs to differ by at laest 3...
I have this for Discrete homework:
A lock has the numbers from 0 to 59 .......A combo is made up of 3 numbers.......How many combos are possible if the 2nd and 3rd numbers have to differ by at least 3
The answer is whatever 60 times 58 times 57 is
I know why the 60 is...
I built a motor for my physics exam....and it works extremely well....it spins extremely fast and there are sparks galore on the commutator.
I have it attached to a 6V lantern battery (the ones a bit bigger than your fist).
How long can I expect the battery to keep...
When plotting potential difference VS current (volts VS amps).....how does one explain the intercept at (0,0) ?
Is it because without potential difference you can't have current and vice versa? Is that true all the time?
I am doing an Ohm's law lab where there is a variable source, a fixed resistor, a voltmeter across the resistor, and an ammeter in series with the resistor.
The fixed resistor is an unknown value but has a tolerance of 5%
You need to figure out its value by plotting...
This seems easy but I'm not getting the right answer!
The question: A 0.5 kg ball is thrown into the air. At a height of 20m above the ground, it is travelling at 15 m/s.
a)How much work was done by someone at ground level throwing the ball up into the air
Ok, for a), Work=Force x...
I am doing a project for my physics course....I have to design a device that uses electromagnetism.
I'm thinking of doing something "different" rather than the boring bells/radios etc..
Would a small-scale model of a maglev train be feasible in everyone's opinion? I am planning to build...
I love Kai Krause's quote "A good analogy is like a diagonal frog"....to me it's one of those oxymorons...like "astronomically small" or "authentic replica"
Is that why it's so popular...because it's a clever oxymoron...or did this guy Kai Krause have another intent for the quote that I...
I'm having trouble with this problem, while preparing for my calculus test this Monday....could anyone help me figure out the solution....I know that I must use the formula P=P(original)e^kt...
Not only that, but even if you went back in time and moved a single MOLECULE of air, and then went back to your regular time, you would change the future immensely.
I believe that the "moved" molecule of air, would at first produce no significant change in the time-line, but eventually it...
