Construct a model of 2-chlorobutane. Which carbon in the chain is a chiral center. What has highest priority. Lowest
Acetic acid, CH3CO2H, is made industrially, by the reaction of methanol and carbon monoxide. If you produce 1.00L of acetic acid (d= 1.044 g/mL) by this reaction, how much energy as heat is evolved.
If a 20.0 °C drop in temperature causes a fortyfold decrease in reaction rate for a certain reaction, what is the activation energy of the reaction
If 45.4g of H2O are produced in the reaction given below, the number of grams of magnesium carbonate used is.?
Indicate if you would expect a disruption of the three-dimensional structure of a protein if the following substances were added and briefly state why
what is the experimental value of Avogadro's number. dropper pipet calibration= 68 drops/ml number of drops of oleic acid in the monolayer=16 drops diameter of monolayer = 15.0 cm
Determine the pH of the solution before the addition of any HNO3. The Kb of NH3 is 1.8 × 10-5. a. 4.74 b.9.26 c.11.13 d. 13.00 e.12.55
considering the given equation koh ch3cooh ---gt kch3coo h2o determine the volume of 0.157m solution potassium
why are the rates of diffusion of carbon monoxide and nitrogen gas are virtually identical at the same temperature?
A fixed quantity of gas at 21 exhibits a pressure of 730 and occupies a volume of 4.40. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.85 while the temperature is held constant.
what is the final temperature of this water/ethanol mixture? (Note: Assume there are no chemical interactions between the water and the ethanol that affect the temperature.)
A person is exposed for three days to identical amounts of two different nuclides that emit positrons of roughly equal energy. The half-life of nuclide A is 18.5 days and the half-life of nuclide B is 255 days.
Calculate the values of Avogadro's number and the Faraday assuming the charge in an electron is 1.602 x 10^-19 coulombs/electron. Also calculate the mass the magnesium anode have lost during the process.
