Consider All the by products that will be formed by E1/E2 processes for the reaction of 2-methyl-2-butanol with concentrated HCl
a) Provide structures for all possible by products
b) which alkene would be favored and why?
2 K + Cl2 ---> 2 KCl How many grams of KCl is produced from 2.50 g of K and excess Cl2. From 1.00 g of Cl2 and excess K?
Chlorine will spontaneously react with iodide to produce chloride and iodine.
Liquid butane, C4H10, is stored in cylinders to be used as a fuel. Suppose 30.4 g of butane gas is removed from a cylinder. How much heat must be provided to vaporize this much gas? The heat of vaporization of butane is 21.3 kJ/mol.
If 85.0 mg of fluorine-18 is shipped at 8:00 a.m., how many milligrams of the radioisotope are still active if the sample arrives at the radiology laboratory at 1:30 p.m. ?
an automobile gasoline tank holds 21 kg of gasoline. When gasoline burs, 81 kg of oxygen is consumed and carbon dioxide and water are produced. What is the total combined mass of carbon dioxide and water that is produced?
delta H=483.6 kJ/mol If 2.0 moles of H2O(g) are converted to H2(g) and O2(g) against a pressure 1.0 atm at 145 degrees C, what is the delta E for this reaction?
Using the same sample of gas ( = 275 , = 43 ), we wish to change the pressure to 2750 with no accompanying change in volume or amount of gas.
A 7.0 liter balloon at room temperature (22 degrees celsius) contains hydrogen gas. If the balloon is carried outside to where the temperature is -3.0 degrees Celsius.
The system H2 (g) + I2 (g) ?? 2 HI(g) is at equilibrium at a ?xed temperature with a partial pressure of H2 of 0.200 atm, a partial pressure of I2 of 0.200 atm, and a partial pressure of HI of 0.100 atm.
A gas made up of atoms escapes through a pinhole times as fast as gas. Write the chemical formula of the gas.
What is the equilibrium constant for the reaction at 87 °C? (R = 8.314 x 10â€"3 kJ/K.mol)
A calibrated flask was filled to the 25 mL mark with ethyl alcohol. By weighing the flask before and after adding the ethyl alcohol, it was determined that the flask contained 19.7325 g of alcohol.
