So far only two of the students asked me about the questions in the midterm 2. When the data was measured, some of the zinc measured along with the copper, resulting in a seemingly higher yield of copper. The precipitates sit at the bottom. The goal of the lab was to recover copper as close to the original copper amount and to demonstrate the Law of Conservation and Mass. You need to familiarize yourselves with the solubility rules in Table 4.

    In your case, sodium hydroxide, NaOH, and copper(II) nitrate, Cu(NO3)2, will dissociate completely in aqueous solution to form cations and. For the reaction:HNO3(aq)+ Cu(s)->NO2(g)+ Cu(NO3)2(aq)+ H2O(l).

    The net ionic reaction is: 4H+(aq) + 2NO3-(aq) + Cu(s) -> 2NO2(g) + 2H2O(l) + Cu2+(aq). 3) If You Use mL (an Excess) Of HNO3, What Volume Of M NaOH Will You net ionic equation for the reaction of concentrated nitric acid with solid copper.
    The goal of the lab was to recover copper as close to the original copper amount and to demonstrate the Law of Conservation and Mass. Selected examples.

    Aqueous Reactions

    For example, when you have This would allow the experimenter to dispose of zinc sulfate, leaving copper behind. For the given Lewis diagram, determine:. Since all atoms H and C surrounding N are less electronegative than N, N should take electrons from other elements.

    Which of the given is not the correct chemical formula for the compound named?

    Once get the average atomic mass, go to the Periodic Table to find the element that has the same atomic mass.

    Selected examples

    The former reaction is like a reverse reaction of the latter. Final Mass of Copper 5. What type of reaction synthesis, decomp, single rep. For a compound KBrO x containing

    In this experiment, aqueous nitric acid, HNO3, oxidizes copper metal to the Metal Mg HNO3 H2SO4 NaOH CuSO4 Cu Cu(NO3)2 CuOCu(OH)2 The net ionic​. Copper metal "dissolves" in nitric acid (HNO3). Actually, the nitrate ion Add the NaOH solution dropwise to the copper solution.

    After a blue precipitate is.

    In the first reaction, copper metal is oxidized by nitric acid to form copper (II) nitrate, If any NaOH or H2SO4 comes into contact with your skin or clothing, wash it off Record your observations of the reaction, and write the balanced net ionic.
    Since a free N has 5 electrons, it needs to get 3 electrons to obtain an octet.

    When the data was measured, some of the zinc measured along with the copper, resulting in a seemingly higher yield of copper. A precipitation reaction is not an oxidation-reduction reaction. The charge difference between any two droplets should give you a whole number of charged particles too.

    Sample Questions Chapter 4

    The goal of the lab was to recover copper as close to the original copper amount and to demonstrate the Law of Conservation and Mass. Bohr model explains very well for hydrogen but not for other elements. The questions are not given, therefore, you have to rely on your memory from the midterm.

    Net Ionic Equation for HNO3 + NaOH (Strong Base and Strong Acid)

    The copper was melted in nitric acid, but was recovered in a solid state after several chemical reactions. The Copper Lab demonstrates stoichiometry in chemistry. The question on bomb calorimeter is same as the question 1 in midterm practice but simpler, since there is no water involved. The precipitates sit at the bottom. A precipitation reaction is not an oxidation-reduction reaction.

    A.

    Cu (s) + HNO3 (aq) → Cu(NO3)2 (aq) + NO2 (g) + H2O (l). B. Cu(NO3)2 (aq) + NaOH (aq) → Cu(OH)2 (s) + NaNO3 (aq). C. Cu(OH)2 (s) → CuO (s) + H2O (l). Copper is digested in nitric acid to form copper(II) nitrate and nitrogen dioxide (​lab expt.) Write a balanced net ionic equation and underline the oxidizing agent. Write the complete ionic and net ionic equations for each of the following reactions: 3 (NH4)2CO3 (aq) 2 NaOH (aq) + H2SO4 (aq) --> Na2SO4 (aq) + 2 H2O (l).
    I will then put the hints here.

    When necessary, you need to add the existing ions and electrons to balance the half reactions. The former reaction is like a reverse reaction of the latter.

    The higher the bond order, the more stable the species, the higher the dissociation energy of the species. The smallest difference will most probably give you one basic charge that a such particle takes. Powered by Create your own unique website with customizable templates.

    When necessary, you need to add the existing ions and electrons to balance the half reactions. To make sure the real ph of the solution is 13, the temperature would have to be lowered and remove excess energy in the solution.

    1. To use half reactions to balance equations, you need to find the reducing agent and its products to make the oxidizing half reaction and to find the oxidizing agent and its products to make the reducing half reaction.
