Draw a mechanism to demonstrate how pyridine catalyzes the hydrolysis of acetic anhydride to two molecule of acetic acid. Is this reaction reversible? why or why not? Show all non-bonding electrons on each atom, circle positive charges, circle a nonbonding electron pair if the atom is negatively charged and indicate electron pain movement with double headed arrows.
Explain the characteristics of a single, double, and triple bonds including why they form
A chemist prepares a sample of hydrogen bromide and finds that it occupies 258 mL at 60 degrees celsisus and 476 Torr. What volume would it occupy at 0 degrees celsisus at the same pressure? Answer in units of mL to 5 decimal places.
What types of crystals are formed by the following solid elements and compounds: BF3 BN (NH4)CO3? In each case, state the types of forces among the particles
What is the vapor pressure of a solution that contains .944 moles Ba(NO3)2 and 30 moles of H2O? The vapor pressure of pure water at the same temperature as the solution is 46 torr

find the molarity of 0.5 grams of sodium chloride is dissolved to make 0.05 ml of solution
How much heat (in kJ) is released when 15.0 L of CO at 85 degrees C and 112 kPa reacts with 18.5 L of H2 at 75 degrees C and 744 torr?
Assume that this rate remains constant for a short period of time What is A 5.00min after the reaction is started? At what time after the reaction is started will A= 0.565M?
Determine what ventilation rate (minimum) in m3/hr will be essential to keep the carbon monoxide concentration in his garage from the dangerous level of 1600 ppmv? What is your answer in this case?
