1. Explain why bothcisandtransisomers are possible for [Co(NH3)2(C2O4)2]-but only the cisisomer is possible for [Co(NH3)4(C2O4)]+.
2. Is more than one geometric isomer possible for the complex [Co(NH3)5Cl]2+ion? Why or why not? If your answer is yes, provide a sketch of both isomers.
3. How many total isomers are possible for the compound [Co(C2O4)2(NH3)Cl]2-? Make sketches of these isomers. Indicate optical isomers and draw them as mirror images.
The remaining white solid in the filter paper has ammonia water poured through it. This turns the precipitate in the filter paper black. The new filtrate is treated with hydrochloric acid (HCl), giving a white precipitate. What metal ion or ions a..
Determine the heats of formation or the steric energies of the exo-and endo-anhydride adducts using a molecular mechanics program. What do these energies tell you about the mechanism of the reaction
Suggest a mechanism for the hydrolysis of n-butyl bromide to n-butanol. Include the elementary steps and indicate the rate determing step
A solid hydrate weighing 2.691g was heated to drive off the water. A solid anhydrous residue remained, which weighed 2.259g. Calculate the per cent water in the hydrate. If the anhydrous residue has a formula weight of 282
When a pink aqueous solution of potassium permanganate, faintly acidified with dilute sulfuric acid was treated with 10% aq. hydrogen peroxide, the reaction took place with the evolution of gas bubbles
We are enabling the trans to cis isomerization of E-1,2,-bidenzoylethylene by irradiating the alkene with light. Why does light allow for the isomerization. What does light do to the alkene.
How do you calculate the coulomb energy of interaction when doing the dissociation energy of an ionic compound. Particularly for the KF molecule
A solution is prepared by dissolving calcium chloride in water and diluting to 500.0 mL. If this solution contains 44 ppm chloride ions, the concentration of calcium ions is how many ppm
During a balloon ascension, wearing an oxygen mask, you measure the weight of a calibrated 5.00-kg mass and find that the value of the gravitational field strength at your location is 9.785 N/kg.
After you filter off the component that does not dissolve in dichloromethane, you will transfer the dichloromethane to a separatory funnel and wash with aqueous 1 M sodium hydroxide. Which layer is the dichloromethane layer
Hydrogen sulfide , H2S , has the characteristics odor of rotten eggs. if a sample of H2S gas at 759.0 torr and 29.0 c in a 3.00-l container is allowed to expand into an 11.0-l container
