The cis-1,4-di-t-butylcyclohexane [cis-1,4-di(1,1-dimethylethyl)cyclohexane] and trans-1,4-di-t-butylcyclohexane stereoisomers can both be drawn but only one of them can easily be synthesized. Draw both conformers and suggest which of them is stable. Suggest a reason why the unstable conformer is unstable.
Calculate the enthalpy change, Delta H, for this reaction per mole of \rm X. Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 \rm J/(g \cdot {^\circ C}) and 1.00 \rm g/mL] and that no heat is lo..
Determine the mass of RbCN required to prepare a 500 mL solution which is .12 M RbCN (MW = 112 g/mol).
Calcium and nitrogen react to form calcium nitride; 3Ca(s)+N2(g)-->Ca3N2(s). If 56.6 g of calcium is mixed with nitrogen gas and 32.4 g of calcium nitride is produced, what is the percent yield of the reaction
Suppose that you are carrying out a dehydrohalogenation reaction on 2-bromo-2,3-dimethylpentane to yield alkenes
Reaction rate laws are frequently used to investigate reaction mechanisms. Would your results to this experiment be consistent with either or both of the following mechanisms?
use the appropriate standard reduction potentials to calculate the value of k at 25 degrees celcius for this reaction
Assume that a pure molecule has a specific rotation of -20 degree. An impure sample of both enantiomers gave a rotation of -4 degree. What is the ratio of (-) molecules to (+) molecules in the latter sample. Details for explanation please! thanks ..
Using the ideal gas law, pV = RT, prove that the volume of one mole of ideal gas is a state function
Write an equation that represents the reaction of 2% aqueous KMnO4 solution with 3-hexene, CH3-CH2-CH=CH-CH2-CH3
The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 10.13 mL of 0.08840 M potassium permanganate (KMnO4) to reach the purple endpoint. A blank required 0.18 mL. Determine the percent WO3 in ..
After the addition of a large excess of acid (in comparison with the acid volume needed to reach the equivalence point) D) tell how many millileters of acid are required to reach the equivalence point
The student found that 8.67mL of NaOH solution was needed to titrate a 0.0544g sample of the acid to the equivalence point. Calculate the mass of unknown required for a 30.0mL titration.
