Write an equation, using the curved-arrow notation, for the acid-base reaction that will take place when each of the following are mixed. If no appreciable acid-base reaction takes place, because the equilibrium is unfavorable, you should so indicate: (a) CH3CH2ONa in ethyl alcohol and ethyne (b) CH3CH2Li in hexane and ethyne (c) CH3CH2Li in hexane and ethyl alcohol
What will be the average atomic mass of element A if percentage abundance of these two isotopes are 48.17 % and 51.83 % respectively. ?
Calculate the specific rotation of the compound. A sample of 150 mg of an organic compound is dissolved in 7.5 ml of water. The solution is paced in a 20-cm polarimeter tube and the rotation measured in a polarimeter
What is the total sample size (in grams) for a sample of magensium nitrite which contains 0.96 g of oxygen
When hydrochloric acid comes in contact with potassium permanganate, what dangerous chemical is released?
how much energy is required to vaporize 98.6 g of ethanol at its boiling point if its Hvap is 40.5 kj/ mol ?
an aqueous solution contains the amino acid glycine (NH2CH2COOH). Assuming that the acid does not ionize in water, calculate the molarity of the solution if it freezes at -2.7 Degree celsius
Using the ideal gas law, pV = RT, prove that the volume of one mole of ideal gas is a state function
determine the molecular formula. Enter your formula as plain text, with carbon first, then hydrogen, the chlorine. So if the formula were C10H21Cl, you would enter C10H21Cl.
If 6.15 mol of ethane (C2H6) undergo combustion according to the unbalanced equation C2H6 + O2 -! CO2 + H2O, how much oxygen is required
Methylbenzene and 1,2-dimethylbenzene mix to form an ideal solution. At 90oC, the vapor pressure of pure methylbenzene is 400 Torr and that of pure 1,2-dimethylbenzene is 150 Torr.
Draw (a) planar conformation and (b) nonplanar (chair) conformation of trans 1,4-dimethylcyclohexane.
