Carbon monoxide gas burns in oxygen to form carbon dioxide gas. Write a balanced equation for the reaction and determine the volume of oxygen needed to react completely with 561 mL of CO at 40.0°C and 1.00 atm.
A hydrogen atom is removed from the first carbon atom of a butane molecule and is replaced by a hydroxyl group. Draw the new molecule formed.
Write structures for all the aldol condensation products you expect from the cross aldol condensation of 4-methyl benzaldehyde and 2-butanone(methyl ethyl ketone)
A 13 gram sample of calcium reacts with bromine to form 24 grams of calcium bromide. How many grams of bromine are used in the reaction?
Compare the relative rate of the foward (EtOH as a substrate) and back reaction (with acetylaldehyde). Use the Michaelis-Menten equation to solve for v when ethanol is 99mM and acetylaldehyde is the substrate and its concentration is 1mM
the starting concentration of reactants (Q) and products (R) are both 15 uM, then the equilibrium concentration of Q and R is what in uM?
Cadaverine are 9.13 and 10.25. If the ends of these molecules look the same, why do they have different pkas?
Lakes that have been acidified by acid rain (HNO3 and H2SO4) can be neutralized by a process called liming, in which limestone (CaCO3) is added to the acidified water. What mass of limestone (in Kg) would completely neutralize a 15.5 billion-liter..
Calculate the pH during the titration of 25.1 mL of 0.565 M dimethylamine, (CH3)2NH with 0.170 M HCl after 14.2 mL of the acid have been added. Kb of dimethylamine = 5.4 x 10-4.
with a solution in them connected by a liquid salt bridge junction filled with KNO3. In one solution you have a graphite electrode that is connected with a wire to a copper electrode in the second soution. The soution in contact with the graphite ..
When 35.0 g of an unknown nonelectrolyte is dissolved in 220.0 g of benzene, the solution boils at 83.2°C. Calculate the molecular weight of the unknown nonelectrolyte. The Kb for benzene = 2.53°C/m. The boiling point of pure benzene is 80.1°C.
Use the Henderson-Hasselbalch equation to calculate the PH of each solution- a solution that contains 0.760% C5H5N by mass and 0.960% C5H5NHCl by mass
