Answer #1

7. Balanced,Chemical equation for the reaction between copper and oxygen to produce Copper (II) oxide.

   Copper (II) oxide is CuO

          2 Cu + O2 → 2 CuO

8. Two balanced, chemical equations for the two steps involved the production of phosphoric acid starting from

    phosphorous and oxygen

   P4 + 5 O2 → P4O10Here P4O10 is Phosphorus pentoxide

   P4O10 + 6 H2O → 4 H3PO4H3PO4 is Phosphoric acid

I recently performed a lab on Chemical Equilibrium. Here is some background on the experiment: -We made a stock solution by combining Fe(NO3)3 and NH4SCN. This made a blood red solution. Then, we added different reagents to see the change of color and the shift of equilibrium. I'm being asked the following question: Based on the color of solutions reported, determine the direction of the reaction's: Fe^3+(aq)+SCN^- --> [FeSCN]^2+(aq) equilibrium shift upon each addition of each reagent investigated and write...

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...

1. Nickel, a common metal used in a variety of alloys, is purified via the Mond process to a very high (> 99.99%) purity. One of the steps in the Mond process involves the reaction of solid nickel with carbon monoxide to produce Ni(CO)4, as shown in the unbalanced equation below. Ni(s) + CO(g) → Ni(CO)4(g) How much carbon monoxide, in grams, is required to purify an impure sample containing 4.22 kg of nickel? (to the correct number of sig...
