molecular science (chemistry) how much math is involved?
922787
At least GCSE (or 'O' level) is needed for any branch of chemistry at post 'A' level. Physical chemistry needs a much higher understanding (involving calculus for rate equations for example and in entropy calculations). Inorganic requires somewhat less but is needed in crytallography and energy level calculations and organic chemistry probebly requres the least. I got by with just a bit more than 'O' level and I did all thee branches.

You might want to try to re-read the questions.  You don't appear to be understanding what is written there.  (I call it a brain fart, but three out of 28 indicates a little lack of understanding)\n\nIf you have re-read the problems, then I offer the below:\n\nYou might want to go over your notes about what a mole is.  It is an amount and a number.  It is a fundamental conceptual building block for the study of chemistry.\n\n  It looks like you expect to be able to plug and chug on these.  Which you can, once you start thinking in terms of atoms and molecules.  Plugging and chugging BEFORE you understand what these little pieces are doing is a recipe for a C.\nIt IS the ATOMIC theory of matter, don't you know.\n\nSo, once you've absorbed that, re-read these three problems.\n\nStill no joy?  Read on, Gunga DIn\n\nFirst H(g) is NOT the element's standard state! I thought everybody learned in grade school about H2 gas - the simplest molecule?  Iodine, I leave to you  (hint a gas???!!! not)\n\nSecond lets see you're making umpteen moles of something and calculate the dS.  that was not the question.  (hint: something about ONE mole)\n\nThird read the problem. your chemical equation is from I don't know where but not from what is in the problem. (hint: products on the LEFT???)

she asked math not included.  You'll need some in depth statistics for genetic engineering and bioinfomatics.  You'll need some amount of differential equation if u want to pursue a career in microbiology and biochem etc etc.  contact me for more info. what exactly is math at 12th grade?  have u taken an actual calculus yet?

Defiantly chemistry, lots of math, and English.

Cell biology is probably the better of the three choices as it deals with cell function and construction, Molecular Biology tends to have a lot more chemistry invoved so if chemistry is not your thing I would definitely give it a miss. Biochemistry is as it says chemistry relevent to biological development. This requires a good basic knowledge of formulae calculations etc..

I think it's math! I've had trouble with it =) maybe chemistry also

You should consult a chemistry textbook, if possible, or if not, look online for an answer; I'm sure there is information or a guide describing how to do it better than I can in a few short sentences. That said, the basic way to draw a molecule (often abbreviated mlcl) is to use each element's symbol(ie sodium=Na, carbon=C, etc) to denote an atom, and to draw a single, solid line for each bond between elements. This line/bond represents 2 electrons, aka one orbital. Most elements like to have 8 electrons in their valence (outermost) shells in order to be stable, but this doesn't always happen; there are many exceptions, hence my suggestion to look at a textbook or online text/guide.\n\nIt gets more complicated when you're dealing with things like organic chemistry or complexes or chelating agents where sharing of bonds/electrons is pretty common and there are more types of bonds. For a simple example, if you had a 6-carbon atom ring, each carbon has 6 electrons in its valence; it wants 8, so what happens, does it get frustrated with its misfortune and self destruct, destroy our little universe? Of course not... there are a total of (6)(6)=36 electrons, and we need (6)(8)=48. How is this possible? Clearly, 36 is not equal to 48. We can't create more. So what happens? As it turns out, carbon, along with most other elements, passed kindergarten with flying colors- they SHARE them, and since it's a symmetrical hexagon shape of identical atoms, they are shared equally. There are all kinds of crazy combos in which the electrons are shared unequally between atoms because of something called electronegativity, but our rules for drawing those lopsided things aren't very different. However, that's for another 'lesson;' don't worry about it for now.\n\nSo, in order to make the carbon happy, we have to share 12, or 6 pairs, of electrons. ([48 needed]-[36 that we have] = 12) \nSince this carbon ring has multiple resonance structures (atom config the same but electron pairs on different atoms), we draw six carbons in a hexagon, with one solid line bond between each, and a dotted circle in the middle- this accounts for all of its resonance structures and provides us with more info, in addition to only needing one drawing to display that info, than using single bond lines only.\n\nSo in conclusion, I've said way more than I really had to... from the level of generality of your question I assume that you don't know too much about chemistry; if you are confused with what I said, then do as I said- look up the info online or get a book. It's not too easy to understand right away but with some patience you should be able to figure it out just fine; good luck.

The molecular geometry is basically the three dimensional arrangement of the atoms that make up a molecule. The study of their geometry gives us the ability to determine several properties such as the reactivity, polarity, phase of matter, color, magnetism, and biological activity.

you should learn how to do your own homework hun you'll never be a chemist with someone else doing your work.\n\n\nuse the molar mass from the periodic table (units = g/1mol)\n\nCl = 35.5\nH = 1.00\n\nMolar mass, formula weight, molecular weight, formula mass = 36.5 grams HCl/1 mol HCl\n\n\nThis is a simple problem is you can't do this problem maybe you should try changing majors.  I hear history or english is nice.

6.02 x 10^23 is the conversion for converting from moles to # of molecules or atoms.\n\nWhen you use the number 19, you are counting the number of atoms in a molecule, not the number of molecules in a mole.

Just count the (sigma) bonds and the lone electron pairs and memorize the cooresponding geometric shapes.  Sorry, but it's the only way.
