A. Its pretty simple, but can be tricky at first. You just have to balance the number of atoms on both sides of the equation ...Reactants ---> Products. For example. H + OH ---> H20. This is very simple example... but see tehre's 2 H's on the reactant hand side and 2 H's on the product side. Same with Oxygen. This equation is balanced. Now lets say it doesnt match up..im making this one up btw. Li + Al ---> LiAl4 The reactants only has 1 Al ...and the right has 4 Al's, so to balance you need to put: Li + 4Al ---> LiAl4 ..balanced. I'm gonan extend it.. now lets say you have something like this.. Fe^2+ + O^-2 ---> Fe2O2 basically you cross the exponential charges to get the final product.. however, you can simplify it to… [cont.]

A. Like a baseball game, it helps to have a scorecard. In other words, what do the words mean when it comes to describing compounds. Once you have surmounted this barrier, balancing follows. Start with "aluminum bromide". If you look it up, it is AlBr3. Why? Aluminum can shed 3 outer electrons to form an Al+3 ion and Br (which, as an element, exists as a dimer, Br-Br), can "suck up" one electron per atom to form Br-. Chlorine is also a dimer (Cl-Cl). However, Cl is more adapt at "sucking up" electrons than is Br, so it can boot the Br- out of the compound, take its electron, and leave a Br atom (which rapidly reacts with another unhappy Br that has been booted out). This may sound silly, but it is about what happens, and leads us… [cont.]

How do you write down chemical equations?
Q. I am having trouble writijng down chemical equations just like this one- Copper(II)Nitrate+ Sodium Hydroxide. How do you write these down and then balance them?
Asked by Johnny Apples - Thu May 29 10:10:35 2008 - - 2 Answers - 0 Comments

A. These are word equations. Sometimes you just derive them from chemical formulas. Or sometimes you make your own. The word equation Copper(II)Nitrate+ Sodium Hydroxide translates to Cu(NO3)2 + NaOH --> By the way, this reaction is not possible because Cu is more reactive than sodium. The rule of thumb for single and double-displacement reactions is that the more reactive element should change places with the less reactive element. Let's invert this equation a bit: Sodium hydroxide + copper (II) nitrate --> This time, sodium can displace Cu from copper (II) nitrate. The products are copper (II) hydroxide and sodium nitrate. Let's translate this into a chemical equation: 2NaOH + Cu(NO3)2 --> Cu(OH)2 + 2NaNO3 recall that… [cont.]

Asked by Kevin Cabrera - Sat Jan 9 19:23:55 2010 - - 2 Answers - 0 Comments

A. We balance chemical equations because they have to obey law of conservation of mass. Law of conservation of mass states that mass can neither created, lost nor destroyed. Therefore we use coefficient in front of reactants and products in order to make sure there are equal number of molecules or atoms on both sides. Consider this chemical reaction, H2 + O2 --> H2O. We see there are 2 hydrogen atoms and 2 oxygen atoms on the left side of the reaction, but there are only 2 hydrogen atoms and 1 oxygen atoms on the right side of the reaction. This does not obey the law of conservation of mass. Therefore we have to balance the reaction to obey the law of conservation of mass. If we put 2 in front of H2 and 2 in front of H2O the chemical… [cont.]

Is there any rule about including physical states in chemical equations?
Q. In which cases do I include the physical state of a chemical? I know it's needed in molecular equations, but what about the following: - skeleton equations - half reactions - net ionic equations
Asked by L.E. - Sun Mar 14 21:32:53 2010 - - 1 Answers - 0 Comments

A. This is purely a matter of convention, so look at examples in your course materials, and use them as models. It is certainly usual to include physical states in half reactions, because very often they involve such matters as dissolution or deposition of a metal, and they are essential in the equations that show precipitation, since the * whole point* is the physical state of the precipitate. So I'm not quite sure what you use skeleton equations for, but in the other cases including physical state is sometimes essential, and can never do any harm.

A. Plenty of logic. I'm still learning, testing, modifying. I was never any good at memorising either, So a metal will generally lose an e- or more to go to stable noble gas configuration, A halogen will gain an e- to form a noble gas config. Using Lewis structure ie total of 8 e- around each atom (well those in the earlier part of periodic table) gives an indication as well. HSAB theory relates to the formation of compounds when in solutuion (Hard Soft Acid Base) the premise like will go with like sometimes help. See anything with a H attached it will probablyl form an acid in aqueos. H+ + OH- will always give water.

Asked by ConcernedGuy - Fri Feb 12 00:19:50 2010 - - 2 Answers - 0 Comments

A. In balancing equations, I generally start with compounds containing relatively rare elements like calcium, aluminium and such. Balancing these is often fairly easy - these heavy elements usually get transferred from one compound to another, and balancing these is simple. Then I go on to try to balance the compounds with common elements like CO , usually by making a match in terms of number of carbon atoms. The very end is balancing simple elements, like O . The reason I keep it last is that because it is only one element, it doesn't affect the measure of any other element and balancing is then a straightforward matter of getting the right coefficient or multiplier to balance it right. Example of balancing: KMnO + HCl KCl + MnCl +… [cont.]

How do you know the states of matter in chemical equations?
Q. In a chemical equation, how do you know that 2Mg + O2 will give you 2MgO in the solid state? I would also like to know how to get aqueous solutions, gases, liquids.
Asked by Jo - Sun Jan 18 10:14:18 2009 - - 1 Answers - 0 Comments

A. 2Mg + O2 --> 2 MgO Mg is a transition metal (look at periodic table), so it's a solid Oxygen is a gas, we breathe that in. When you burn metals with oxygen, you will always get a metal oxide (a solid). Solids: sulfates, nitrates, carbonates, graphites, compounds with very heavy (huge) molecular weights Usually diatomic stuff, diatomic halogens and small hydrocarbons are gases. Aqueous solutions is trickier, it needs to be in water and be water soluble (usually ionic compounds) As for liquids, Mercury is a liquid. In compounds, usually you wouldn't know if it's a liquid or not. States of matter should be implied in a problem or given to you. Temperature is also usually a hint but you need more experience to know it all better.
