If NaHCO3 reacts with H2SO4 in aqueous solution will it make NaHSO4 or Na2SO4? Are there other ways to make NaHSO4?

im trying to obtain strontium metal from the nitrate salt. i was thinking of making a solution of the salt and adding pure magnesium metal to reduce the strontium. two questions: -would this work? -would the strontium dissolve? if it doesnt work, do you have any other ideas?

is there anyway one could change mercury sulfide to pure mercury

I thought it might be a fun idea to build a rechargable battery for a high school chemistry class I wired the batter up its a copper pipe and a zinc nail the battery involves plugging one end of the pipe filling it with vinegar and putting the nail in. I wrapped a wire around the nail and then another wire around the pipe and it electroplated my nail I would have to switch the wires because I would want to have the copper removed from the zinc nail but I am not sure if electroplating is what happens when you recharge a battery if someone knew if electroplating and battery recharging are pretty much the same process I would appreciate it.

Just curious

I think when potassium metal is put into a hydrogen peroxide solution is more dangerous than puting in HCl, right? The energy released more? Or just the energy released within a period of time is high?

I need help finishing this equation. Fes + Cu2S + O2 -->

How would I figure out this question? 1. what is the partial pressure of nitrogen in a container that contains 2 mos of oxygen, 3 mols of nitrogen, and 1 mol of carbon dioxide wehn the total pressure is 900 mmHg I want to try and learn how to do the question...so if anyone could help that would be great...THANKS!!

I put some hydrogen peroxide in a container in my kitchen freezer to get more pure h2o2. And without thinking if the gases are harmful . Someone please tell if the it is ok.

In my chemistry, it has listed several compound ions, but it does not explain how they are formed and how their charges are found........ For eg, NH4 with 1 positive charge OH with 1 negative charge SO4 with 2 negative charges HCO3 with 1 negative charge and so on..... How compund ions are formed, and how their charges are found? according to the formula? Maybe possible, tell me what kind of property does the formation of compund ions have thx in advance Albert

Can some1 tell me if the two equations below are correct: (1)H2SO4(aq) + CuO(s) --> CuSO4(aq) + H2O(l) [net ionic equation: 2H+(aq)+ 2OH-(aq) --> H2O(l)] (2)H2SO4 (aq) + Cu(OH)2(s) --> CuSO4(aq) + 2H2O(l) [net ionic equation: 2H+(aq) + 2OH-(aq) --> H2O(l)] i'm not too sure on the states of CuO and Cu(OH)2

When ammonium nitrate undergoes decomposition, only gases are produced, according to the equation NH4NO3 > N2O + 2H2O What is the total volume of gases produced at 546K and 1 atm pressure when 240g of ammonium nitrate undergoes the above decomposition reaction? a) 9 x 22.4L b) 6 x 22.4L c) 12 x 22.4L d) 18 x 22.4L e) 3 x 22.4L I got (a) but I'm not sure if i did it correctly...All I did was I found mols of H20 and mols of N20 which were 6 and 3, respectively. Then I added them to get 9 and picked a. I'm pretty sure this is totally wrong but I was trying to do PV=nRT but I didn't know how.

I have 3% of NaCl stock solution. How do I make these concentrations with only 3% of NaCl? How much distilled water do I need to dilute before I can get these concentrations? -> 0.2% -> 0.4% -> 0.6% -> 0.85% -> 1% -> 2% -> 3%

Can some1 explain to me why transition metals have more than one oxidation state?

I am planning to demonstrate the chemical principle of [extreme] decomposition at a science fair in one of my local middle schools. Obviously, the material that will be used is dry nitrogen triiodide. So I need some suggestions: 1. How much iodine (grams) should I use when I prepare the wet nitrogen triiodide by mixing solid iodine with concentrated aqueous ammonia. I was thinking about 2-4 grams. 2. How long will it take for 2-4 grams of wet nitrogen triiodide to be dry enough to detonate upon touching?

When I am doing the experiment, mostly when dissolving something, My teacher requires us to use de-ionized water, why? what is de-ionized water? and Why just not use tap water?

I few weeks back I order some barium nitrate off ebay. I was wondering the best way to make it burn nice and green? I had a quick try with plain sugar mix, but no luck. I'll take some pictures etc to show you the results..

in order to get good acid, do the batteries need to be charged? or can they be old discarded dead ones from the back of pep boys?

Can some1 help me out! I know that copper can form Cu2+ ion but how does this actually happen? I know it is a transition metal and that it can form more than 1 ion, but can some1 give me an example of how it actually forms a 2+ ion? What does it bond with for that to happen? Thanks!

Can someone explain why this is? In [Fe(en)3][picrate]2 this means it is FeII. So using valence bond theory they should be sp3d2 hybrid orbs. Crystal field theory is not an option in this problem, which would have made more sense to me. So in [Fe(1,10-phenanthroline)3][ClO4]2 it is also FeII but it must be in the low spin state meaning that all the e- are paired in the remaining 3d orbs not used for the hybrid bonds. While in the [Fe(en)3][picrate]2 it must be using the 4d orbs and leaving the 3d orbs alone to have the 6e- spread out over the five. Both ligand types are bidentate and both bond by the nitro. This explains the difference in magnetic moment, but why in the h…

I know this is basic stuff, but does the electrolysis of water produce oxygen and hydrogen, or hydrogen and OH-. Or are they the same thing?

I was just wondering what would be the best way to detect if water contains fluoride or fluoride compounds? Thanks.

I read A Short History of Nearly Everything (Bill Bryson) a few months ago, and it had some interesting tidbits about Phorphorus. For instance, the discoverer (cant remember who it was) was trying to get gold out of urine. They attributed gold to the color of the urine, so thats why they thought they could get gold out of it. Anyways...it said that after using "a few recondite practices" he turned the urine into a waxy substance that ignited spontaneously. My question is... Does anyone know what these 'recondite practices' may be? Thanks in advance.

ok, so i just got in a huge argument on a rocket board. this guy keeps telling me that sugar has a much higher impulse than BP and is a lot more predictable...is there any truth to this argument?

Can one do anything interesting or useful with sodium aluminate? (it is byproduct of making hydrogen from NaOH, H2O and Al)
