Citric acid is made by fermentation of sugars such as sucrase in air. Oxygen is consumed and water generated as a by product
a. Write a balanced equation for the overall reaction that occurs in the manufacture of citric acid from sucrase
b. What mass of citric acid is made from 15.0kg sucrase?
Acetylene reacts with hydrogen in the presence of a catalyst to form ethane according to the following reaction:
The pressure of a mixture of acetylene and an excess of hydrogen decreases from to in a vessel of a given volume after the catalyst is introduced, and the temperature is restored to its initial value after the reactionreaches completion. What was the mole fraction of acetylene in the original mixture?
At 600 K, the rate constant for the first-order decomposition of nitroethane
is 1.9 ร 10-4s-1 . A sample of is heated to 600K, at which point its initial partial pressure is measured to be 0.078 atm. Calculate its partial pressure after 3.0hours.
Question:For each of the following molecules or molecular ions, give the steric number, sketch and name the approximate molecular geometry, and describe the directions of any distortions from the approximate geometry due to lone pairs. In each case, the central atom is listed first and the other atoms are all bonded directly to it.
(a)
(b)
(c)
(d)
Quantum mechanics predicts that the energy of the ground state of the atom is . Insight into the magnitude of this quantity is gained by considering several methods by which it can be measured.
(a) Calculate the longest wavelength of light that will ionizeatoms in their ground state.
(b) Assume the atom is ionized by collision with an electron that transfers all its kinetic energy to the atom in the ionization process. Calculate the speed of the electron before the collision. Express your answer in meters per second and miles per hour (miles).
(c) Calculate the temperature required to ionize a atom in its ground state by thermal excitation. (Hint: Recall the criterion for thermal excitation of an oscillator in Planck's theory of blackbody radiation is that.)
