Question- How many electrons does the LUMO of 2,4 hexadiene have in its ground state? Draw all sets of orbitals.
I don't know how to reach these answers so please show the steps, thank you!
But a3.00 g sample of Mg dissolves in nitric acid to give 18.3 g of magnesium nitrate, which gives 4.98 g of MgO when heated to 1000 degrees Celsius. These results illustrate which law, theory or hypothesis?
When 10.0 g of NH3 reacts, the actual yield of N2 is 8.50 g. What is the percent yield?
Presume that data were collected for 10000 sets of automobile brakes. The mileage at which each set had been 80% worn through was recorded. The average was 62700 as well as the standard deviation was 10400 miles.

a sample of co2 g in a piston at 7.5 atm and 1090. l is allowed to come to equilibrium against a constant external
Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
Predict the freezing point of a solution of 10.0 g of carbon tetrachloride, CCl4, in 100.0 g of benezene, C6H6. For benezene

To extract quinine from an aqueous solution, what pH should be used and why? I'm not sure if you use both pKa's or just one.
Another bottle holds 120 tablets, each containing 180 of aspirin, and sells for $3.95. Calculate the value in milligrams of aspirin per dollar.
Solve for the total moles, then the total pressure of the mixture using the Ideal Gas Law. Next find the mole fraction of Argon and solve for partial pressure of Argon.
The following properties were measured for an unknown hydrocarbon in a lab with an ambient temperature of 28 degrees Celsius and a barometric pressure of 28.9 inches of mercury (1 inch Hg=25.4 torr)
