When copper(cu) metal reacts with nitric acid(hno3) according to the equation cu + 4hno3 [yields] cu(no3)2 + 2no2 + 2h2o which of the following does [u]not[/u] occur. Save the copper search this site + 4hno3(aq) - cu(no3)2(aq) + 2no2(g) + 2h2o(l) the copper was combined with nitric acid, creating aqueous cupric nitrate (blue . Cu=copper hno3=nitric acid cu(no3)2=copper nitrateno3 is nitrate with valency of -a million and copper with +2 so thats y u have a 2 exterior the bracket for no3 no2=nitrogen dioxide and h2o is water. Cu(no3)2(aq) + 2naoh(aq) cuoh2(s) +2nano3(aq) c) reaction c: if heat was added to copper(ii) hydroxide, a decomposition reaction would occur as the reaction would.

Best answer: the no2 was produced from some of the hno3 it's a redox reaction because oxidation, cu(s) - cu+2 and reduction, n+5 (in hno3) - n+4 (in no2). Zn(s) + h2so4(aq) - znso4(aq) + h2(g) the equation shows that solid zinc would turn form with sulfuric acid to make an aqueous solution of zinc sulfate this would allow the experimenter to dispose of zinc sulfate, leaving copper behind. Copper is oxidized by concentrated nitric acid, hno 3, to produce cu 2+ ions the nitric acid is reduced to nitrogen dioxide, a poisonous brown gas with an irritating odor: cu(s) + 4hno 3 (aq) —— cu(no 3 ) 2 (aq) + 2no 2 (g) + 2h 2 o(l).

Cu + hno3 = cuno3 + h2 or copper nitrate and hydrogen gas cu + 4 hno3 -- cu(no3)2 + 2no2 + 2h2o the brown colored gas that comes of the reaction is no2. Chemistry copper cu s 4hno3 aq cu no3 2 aq 2no2 g 2h2o l ap chemistry 12/13/11 round-trip copper reactions lab the purpose of this lab was to evaluate our skills of decanting a supernatant liquid without losing the solid and successful completion of a series of reactions. The reactions you have mentioned are of the following type: cu(s) + 4hno3 (aq) → cu(no3)2 (aq) +no2 (g) +h2o(l) combination of single displacement or substitution reaction and chemical . Calculating the standard heat of formation of icl (g) is actually the same as calculating δh 0 for the reaction (1/2)i 2(s) + (1/2)cl 2(g) ® icl (g) therefore, you have to use all four given equations to produce the desired equation and then calculate δh 0 accordingly. 3cu(s)+ 8hno 3 (aq) -3cu(no 3) 2 (aq) + 2no(g) + 4h 2 o(l) if this reaction took place rather than the 1st reaction, would your yield of cucl be affected assuming you started with the same amount of copper metal.

Brass is an alloy of copper and zinc the mass percentage of copper in brass can be determined by first reacting it with concentrated nitric acid, and then using a colorimeter to analyze the color intensity of the copper(ii) nitrate solution that forms cu(s) + 4hno3(aq) —— cu(no3)2(aq) + 2no2 . Start studying experiment 28 chemistry of copper learn vocabulary, terms, and more with flashcards, games, and other study tools. Please help me again with my lab in chemistry show a solution if possible calculate the mass per liter of solid lead (ii) phosphate (k sp = 100 x 10. What are the balanced half-reactions to cu + 4hno3 cu(no3)2 + 2no2 + 2h2o i need the final balaced redox reaction and the balanced reduction half-reaction i have the balanced oxidation half-reaction already. Cu(s) + 4hno3(aq) —— cu(no3)2(aq) + 2no2(g) + 2h2o(l) once the concentrated nitric acid begins to oxidize the copper creates a brownish gas gas bubbles are noted during the chemical reaction.

Using stoichiometric proportions we see that for every mol of copper used, we produce 2 mols of silver copper: 635g/mol silver : 1079g/mol convert g to moles of ag,. When it reacts with o2 it turns to the brick red no2 that we observe when copper metal reacts with nitric acid + 4hno3(aq) -- cu(no3)2(aq) + 2h2o(l . 3 cu(s) + 4hno3(aq) -- cu(no3)2(aq) + 2no2(g) + 2h2o(l) a)write the net ionic equation for the reaction of concentrated nitric acid with solid copper.

Reduction: 2no3-(aq) + 2 e- ----- 2no2(g) (3)notice that this time there are oxygen atoms in the reduction step that are not balanced when this happens, add as many water molecules on the right as are needed to balance the total oxygens on the left. How to balance this redox reaction (using half reaction method):$$\ce{cu + hno3 - cu(no3)2 + no + no2}$$ you really can't balance this equation for two reasons.
