A. so you know that u have 30.4 % nitrogen by mass, you can write that as: 30.4 g N then u know you have 69.6 % O left but you can write that as 69.6 g O ( 100 - 30.4 = 69.4) ok so now you need to calculate the empirical formula: you can do that by taking each respective element and finding the value for one mole of that element for example: 1) 30.4gN x ( 1 mol N / 14.06g N) and you get: about 2.16 mol of N (since the grams cancel) 2) 69.6g O x (1 mol O / 16.0g O ) and you get: 4.35 mol O. now you found the two elements for one mol, so you take the smallest one and divide all of the values by it ex: 1) 2.16 / 2.16 = 1 2) 4.35 /2.16 = about 2 ok so now yuo know that the empirical formula is equal to (N1)(O2)… [cont.]

How do you tell if a compound is organic?
Q. Well my bio teacher told me that if a compound has 2 or more carbon atoms, then it is organic. Therefore, she said that something like methane wouldn't be organic. However, I've been searching around the internet for a formal definition, and I've come up upon people saying that all an organic compound needs is carbon bonded with hydrogen or something of that nature. Thus methane would be organic? So i just want to clarify on what makes a compound organic. If just by looking at its formula, how can you determine whether the molecule is organic or not?
Asked by Cowbandit - Thu Oct 1 20:00:33 2009 - - 1 Answers - 0 Comments
A. Yes methane is organic, ANE on the end meaning it's in the family of alkane single carbon to carbon bonding it's a natural gas. Alkane - single carbon to carbon bonding Alkene - double carbon to carbon bonding Alkyne - triple carbon to carbon bonding yes what is your teacher thinking about i don't know but it's a organic compound. Methane's molecular formula is CH4 so there are 1 carbon and 4 hydrogens. If you burn methane in the presence of oxygen you will be getting carbon dioxide something interesting.

Q. What is the difference between a covalent compound and an Ionic compound? Give specific examples to support your response.
Asked by PeejayButta - Fri Jul 11 20:20:01 2008 - - 3 Answers - 0 Comments
A. Covalent bonds = shared elctrons Ionic bonds = transfer of electrons First, you must know that a driving force for bonding is for an atom to fill its outermost shell with 8 valence electrons (except hydrogen, which only wants 2). Covalent bond = O2 (2 oxygens bonded together) Oxygen has 6 valence electrons, so that means 2 oxygen atoms will have a total of 12 valence electrons. However, most atoms (except hydrogen) need 8 valence electrons to fill their outermost orbital. So in order for 2 bonded oxygen atoms to have a full orbital of 8 electrons each, then they must need a total of 16 valence electrons right? (8 + 8 = 16). No. Not with covalent bonding.

Can a compound bow be shot without using an arrow release?
Q. I'm planning on buying my own bow soon. But I was having trouble deciding between a recurve bow or compound bow. For the Compound Bow, is it possible to shoot an arrow without using a arrow release? (can I shoot a arrow with a compound bow just like how I shoot an arrow with a recurve?)
Asked by Myth - Wed Feb 24 20:55:20 2010 - - 7 Answers - 0 Comments
A. Yes you can. I used a finger tab for over 30 years shooting a compound bow.In the beginning it worked out great. But as the compound bows got shorter, faster, with lower and lower brace heights they became less and less forgiving. It became almost impossible even with a bow tuned to perfection to shoot a broadhead at a deer and hit the spot you were aiming at under hunting conditions. I finally went to a release 3 years ago and the accuracy problem with the broadheads completely went away. But if your goal is just to target practice with field points as you stand on the ground the release is not necessary. But if your goal is to bow hunt if you get a compound get a release for it before you even leave the archery shop.

A. CsBr is the chemical formula. Cs is in the first column on the periodic table and has a +1 ionic charge. F is a member of the halogen family and has a -1 ionic charge. The charges cancel and the formula is CsBr, cesium bromide. When writing the formulas for ionic compounds, the ionic charges must cancel each other out.

A. D. None of them. It isn't A because a comma cannot create a compound sentence out of two ind. clauses--that would be a run on sentence, or comma splice. B is wrong because you need two independents, at least C. nice

How can you determine how many bonds a compound will form?
Q. How could you find out if a compound has a double, or triple bond other than by drawing the lewis dot structure? For example: How could you easily pick out which of these compounds form a double bond: H2O CO NH3 H2S O2 Thanks! Best answer will be chosen!

A. by looking at their valence electron. so say O2 each has six valence electron so u can for double bond and single bond from it. Sulfur had six and hydrogen has 1. H2S you can make a double bonds there. you have to write a lewis structure then u will get it.

A. I was trying to find a topic list that I had that had some depth to it. There was an interesting natural product that had antiangiogenisis properties that I had pursued. However, I don't remember the name of it. If you want to learn more about his search for Judah Folkman. Wikipedia has background information about him. I learned about him from a NOVA program about his novel idea for cancer treatment. This whole area he pioneered has developed several anti-cancer drugs. If you are doing literature searching in SciFinder, for example, then you can easily use Boolean logic to limit the amount of hits that are most topical for you. If you are doing internet searching, it is virtually the opposite. A limiting term or a name or target that is… [cont.]
