"Solid dinitrogen pentoxide is added to water." I got this as my answer: N2O5 + H20 -> 2HNO3. Do I need to break 2HNO3 apart since it's a strong acid? I thought it wouldn't since I thought it was a synthesis problem. I read online that this was the answer (N2O5 + H2O ->H...

A concentrated solution of ammonia is added to a solution of zinc oxide? NH3 + ZnI2 => ?? An excess of nitric acid solution is added to a solution of tetraaminecopper (II) sulfate. HNO3 + ? => ?? Zn forms the Zn(NH3)4^+2 ion. It MAY form some Zn(OH)2 at small amounts of ...

Why is a solution of KNO3 neutral and not acidic? K^+ doesn't hydrolyze (H2O has a stronger attraction for the OH- than K^+) and NO3^- doesn't hydrolyze (H2O is a stronger base than NO3^- meaning that H2O will not donate a proton to NO3^-). Looking at it another way, suppose ...

balance this equation. prove that it obeys the law of conservation of mass by using formula masses. HNO3 + Mg(OH)2 ---> HOH + Mg(NO3)2 is this balanced? 2HNO3 + Mg(OH)2 ---> HOH + Mg(NO3)2 I dont understand the formula masses part do i just find the mass of each? It isn'...

Can someone please tell me which of the following I have wrong?? I know that one or more is incorrect, but I'm not sure which ones... Match the following Bronsted acids with their conjugate bases. Choices: SO42-, SO32-, CO32-, HPO42-, HPO32-, Cl-, F-, NO3-, NO2-, HSO4-, HSO3...

How is it possible for me to tell which of these solutes will produce an acidic solution when dissolved in water? LiOH CH3CO2K H2SO3 KOH NaOH NH4NO3 NaOH NaOH can't be the only one... Molecules that produce OH^- when dissolved in water will be basic. Examples:LiOH, KOH, NaOH, ...

Classify the following as: Weak or strong acid, weak or strong base, salt (from weak/strong acid and base). If appropriate, split the formula into its component ions. HNO3 So far, all I have is: HNO3 + H2O -> NO3^- + H3O^+ And I know HNO3 is a strong acid. What would I do ...

Chem--- last lab question!!
My lab partner performed one section of a lab on her own while I worked on something else. This section involved first adding a drop of 6 M NaOH to Zn(NO3)2. A precipitate forms. This is repeated in three separate test tubes. In each test tube, a different substance is added. ...

Does EDTA react with light? I forgot to cover a dilute bottle of EDTA (about 0.01M) and was wondering if that would have any affect on the solution I don't think so. I have used EDTA many times and never covered it or used a tinted container. okay =) i posted an answer to the ...

Can u help me in balancing the following eqn. through oxidation no. method or half reaction method. Also please show and explain the steps. HNO3(aq.) + KI(aq.) -----> NO(g) + I2(s)+ H2O(l) + KNO3(aq.) Hoping for a quicker response. I goes from -1 to 0 N goes from +5 to +2 ...

Hey mr. Bobpursley, I didnt get ur answer clearly.Can u please explain me in proper steps.i tried to balance from ur hint but coudnt do that. HNO3 + KI ----> NO + I2 + H2O + KNO3 see the other post. I am not going to do all the steps for you. see the other post. I am not ...

Basically what color is yellow when they say "Yellow"? The titrations I have done are light yellow when approaching the end point but whatever color you see is what you get, I suppose. So titrate to a very light color. Would the extra 5ml of starch indicator have any effect on...

Breathing too much alcohol or too much HNO3 surely would not be very good but I doubt there would be a reaction that would produce toxic fumes other than the fumes from the HNO3 and/or the ethanol. On similar note, just yesterday an 18-wheeler spilled a little "hazardous waste...

calcium nitrate + sulfuric acid =caso4+? write a balanced chemical equation for this reaction including states. Ca(NO3)2 + H2SO4 ==> CaSO4 + 2HNO3 You don't have enough information to provide states. CaSO4 will be a solid so you write CaSO4(s). H2SO4 will be (l) if it is ...

Calculate the concentration of an aqueous HNO3 solution that has a pH=5.08. pH = 5.08. Convert that to (H^+). Since HNO3 is a strong acid and it is 100% ionized, (H^+) = (HNO3).

write a balanced chemical equation for calcium nitate plus sulfuric acid produces calcium sulphate and ? This is a metathetical reaction, I think more properly called a double displacement reaction now. Just change + and - partners. Ca(NO3)2 + H2SO4 ==> CaSO4 + HNO3. I will...

if you added sulfuric acid to calcium nitrate what products in addition to calcium sulphate would you get if any ? if you start with calcium nitrate mixed into H2SO4 (aq), wouldn't you get a solution of nitric acid? H2SO4 + Ca(NO3)2 >>> 2 HNO3(aq) + CaSO4(s)

Pb(NO3)2+HCl-->PbCl2+HNO3 Pb(NO3)2+2HCl-->PbCl2+HNO3 I'm not sure. Long ones are a bit more difficult.
