Chemical Formula Answers
How do I determine if a chemical formula is solid or liquid?
Q. In terms of writing down chemical formulas, I understand balancing the charges, placing parentheses around polyatomic ions, and the like. But once you write down the element symbols and subscripts and then have to write down if it is (aq), (s), (g) etc, how do I determine which is in a specific formula?

A. There isn't any simple rule. I'd say just leave it off unless you know what it is. If for some reason you have to know, in a paper library you should find the Chemical Rubber Company's Handbook of Chemistry & Physics. It has tables of organic and inorganic chemicals with all their property information, incl MP, BP, etc. Organics and inorganics are in separate tables.

What chemical formula did these investigators assume for water?
Q. Hydrogen and oxygen always react in a 1:8 ratio by mass to form water. Early investigators thought this meant that oxygen was 8 times more massive than hydrogen. What chemical formula did these investigators assume for water?

What is the chemical formula of aluminum reacting with oxygen?
Q. I know aluminum has 3 valence electrons and oxygen has 7, but if anyone could explain the chemical formula to me it would be great.
Asked by William - Thu Dec 4 17:54:19 2008 - Chemistry - 2 Answers - Comments
A. The chemical formula of aluminium oxide is Al2O3 An aluminium ion has a 3+ charge, because it loses 3 electrons when it reacts. An oxygen ion has a 2- charge, because it gains 2 electrons when it reacts. In aluminium oxide, the charges of the ions need to cancel out. So... 2 aluminium ions --> 6+ total charge , 3 oxygen ions --> 6- total charge The charges cancel out.

What is the difference between Myodil and Pantopaque chemical formula?
Q. Myodil (UK) and Pantopaque (USA) was an old oil based contrast medium that was used in x-ray. However, the Chemical formula was different. What are those differences? And how would such differences react within the CSF of the body and through daughtering. Thank you.
Asked by DEREKM - Wed Jun 27 09:39:09 2007 - Chemistry - 1 Answers - Comments
A. Myodil and Pantopaque were exactly the same product, just named differently. The chemical formula is C19H29IO2, with the IUPAC name is ethyl 10-(2-iodophenyl)undecanoate. Structure picture can be found here : Iophendylate is a myelographic oil-ester initially introduced for use in small amounts (1-2cc) for locating spinal tumors. Later, it was found to cause adhesive arachnoiditis. Because these substances are hyperbaric once they were placed in the subarachnoid space they would migrate to the distal portion, where they remained, producing progressive scarring.

What is the chemical formula for dirty water?
Q. This is a Chemistry problem that I just don't understand What is the chemical formula when dirty water is boiled for purification process, the temperture is brought up to 100C for 15 minutes.
Asked by Lori - Wed Jan 13 20:12:25 2010 - Chemistry - 2 Answers - Comments
A. Dirt is not on the periodic table, as it is not an element. There really isn't a chemical formula for this. Boiling water will not get rid of dirt, or most poisonous dissolved solids. Sometimes, boiling will cause certain dissolved carbonates to lose CO2 and precipitate. Usually boiling is used to kill microbes, such as if there has been a problem with the purification of the water supply. You wind up drinking a very dillute microbe soup (but at least they are dead microbes), so you get a little extra protein with your water)

What is the chemical formula of an eggshell?
Q. I need to know the chemical formula of an eggshell and for acetic acid. Also what the balance formula is.
Asked by Foxy - Tue Sep 5 17:29:27 2006 - Other - Science - 2 Answers - Comments
A. The acetic acid has the empirical formula CH2O and the molecular formula C2H4O2. The eggshell is largely crystalline calcium carbonate. Chemical formula: CCa O3. To balance the equation, we must ensure that the sum of the atomic numbers on each side of the equations are equal (required by the conservation law of electric charge), and that the sum of the atomic masses on each side are also equal (required by the law of conservation of baryon number).
