Chemistry help: reaction with HCl, SO2 and H2O?
OK, I dont know what part (a) was, but here goes. The molecular weight of SCl4 is 174 grams/mole Number of moles of SCl4 in 2.624 gm = 2.624/174 = 0.01508 moles We know that 1 mole of SCl4 reacts with 2 moles of water to give us one mole of SO2 and 4 moles of HCl. So, number of moles of water to be reacted = 2*0.01508 = 0.0301 moles This corresponds to 18*0.0301 gm = 0.54289 grams of water. Moles of HCl formed = 0.06032 Grams of HCl = Moles * Mol wt. = 0.06032 * 36.5 = 2.2016 grams of HCl --Note-- I have used molecular weights that are the rounded off to the nearest half integer. You can follow the same approach with exact molecular weights and get a more perfect answer.
Chemistry Reactions Help??
My Guess is you are looking for the equation, so- Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + H2O(l) + CO2(g) colourless gas is given off Na2C2(s) + H2O(l)→NaOH(aq) + C2H2(g) Reaction is violent. Effervescence occurs and C2H2 (acetylene or ethyne) is released. AlCl3(aq) + 3 NaOH(aq) → Al(OH)3(s) + 3NaCl(aq) You from a white gelatinous precipitate of aluminium hydroxide. NOTE- SINCE YOU ARE USING EXCESS NaOH, WHITE PPT OF Al(OH)3 WILL DISSOLVE (since aluminium hydroxide is amphoteric) Al(OH)3(s) + NaOH(aq) → NaAl(OH)4(aq) ionically, Al(OH)3(s) + OH-(aq) → Al(OH)4-(aq) NaAl(OH)4 is known as Sodium tetrahydroxyaluminate III
Would this be Cu3N2 or CuN2? Chemistry reaction help!!!?
this is what'd i'd put if it were my hw...dunno if its right, but its what i'd put Cu + NH3 ==> Cu(NH4)2 hope it helps

Chemical Reactions: HELP!?
Yes, I'm not a chemist... but I do like chemistry. I'd like it even more if it wasn't so intricate with so many unnecessary distinctions to make between stuff! But anyway, I'm doing a chemical reactions unit and it's not THAT bad, there's single displacement, double displacement, synthesis and decomposition... I just got lost when we brought in combustion and sorta got neutralization. I have some chem. problems here, can anyone explain them to me? I know the rxns but I just don't get combustion and whether they're aqeuous or not. Here: 1.) Acetic Acid + Sodium bicarbonate (baking soda) = ? 2.) Copper wire in flame makes...? 3.) Mg + lead II nitrate makes...? 4.) hydrochloric acid + sodium hydroxide= ? 5.) lead II nitrate + potassium iodide=? 6.) copper II sulfate + iron=? 7.) copper II sulfate pentahydroxide in flame makes...?! Is hydrogen aqueous? Is iron? Is Mg? And when is it a gas or liquid? Can you balance the eqns. too plz? Thanx for your help!
A chemistry reaction rate question??? Plz help!?
Looking at the unit of k this is a zero- order reaction 0.015 = - 0.63 t + 0.134 - 0.119 = - 0.63 t t = 0.19 s Sorry , it is a second - order reaction : 1 / 0.015 - 1 / 0.134 = 0.63 t 66.7 - 7.46 = 0.63 t t = 94.0 s

Rates of Chemical Reactions...help?
The mechanism is made up of the distinct "steps" that the reacting chemicals are believed to go through as they convert into the products of the reaction. In organic chemistry, the mechanism of a reaction includes how the bonding electrons move about within the molecules as existing bonds are broken and new bonds are formed. It also includes the changes in conformational structure of the molecules as they go through the reaction process. Of particular importance are what are called 'transition states' and 'intermediates'. A transition state is a state that the molecule goes through as it changes into a product molecule, and can not be isolated. An intermediate, however, is something that has a distinct lifetime within the reaction mixture and can usually be trapped or isolated by some means. The rate of a reaction is determined by how long it takes for the reaction to go through the various steps of its mechanism. No reaction can proceed faster than what is called its "rate determining step". Here's an example. If we mix A and B we get C as in A + B ---> C Now suppose we did an experiment and measured how fast C was being produced by the reaction, and we found that it was produced the fastest when we added twice as much B as A. That would tell us something about how the reaction occurs. We could conclude that the actual reaction is A + 2 B ---> C What it might not tell us is whether or not the reaction proceeded by a number of steps, as in A + 2B ---> D D ---> C If the reaction of D to produce C occured much faster than the reaction A + 2B ---> D, we would not be able to tell the difference between the production of D and the production of C. Now suppose that the reaction D ---> C was much slower that the other one. Our experimental results would not be related to how much of A and B we added, because neither one of them determines how fast the reaction goes, and we would get a result that is consistent with having that other step in the reaction mechanism. Reaction kinetics is a very mathematical field, but ebcause it is mathematical, the results of experiements show quite specifically how a particular reaction occurs and it is thus very useful.
