Which of the following has only a single peak in the proton NMR spectrum
.tert-butylchloride .2-chloride-3-methyl-2-butene.tert-butylchloride and 2-chloro-3-methyl-2-butene
3H2 + N2 -> 2NH3. At 200 degrees C in a closed container, 1.00atm of nitrogen gas is mixed with 2.00atm of hydrogen gas. At equilibrium, the total partial pressure is 2.00atm.
A chemist measures the amount of bromine liquid produced during an experiment. She finds that 766.g of bromine liquid is produced. Calculate the number of moles of bromine liquid produced.
What mass of HCl gas must be added to 1.00L of a buffer solution that contains [acetic acid]= 2.0M and [acetate]= 1.0M
How many liters of H_2 would be formed at 704 mm Hg and 14 degrees C if 21.5 g of zinc was allowed to react?
Consider a distillation column that is fed 1000 kg/hr of an equimolar mixture of benzene and cyclohexane. Theof the benzene distillate stream is to contain 90 % with a benzene mole fraction of 0.95.
Calculate the heat change of the calorimeter (Qcal) for this process and report it below with the correct number of significant figures
Since there are that many Moles of KOH there must be equal moles of the acid. So 4.14*10-3moles/.05L= X M of initial acid== .0828M?

Determine the second order rate constant from the initial concentration and half life and what is the second order rate constant?
A student found that her mixture was 15% NH4Cl, 20% NACL, and 75% SiO2. Assuming her calculations are correct, what did she most likely do incorrectly in her experiment?
The empirical formula of a compound is found to be P2O5. Experiments show that the molar mass of the compound is 560g/mol. What is the molecular formula of the compound?
mercury barometer with an inner diameter of 10.00 mm? Recall that the area of a circle is A = ? r2 and that 1 N = 1 kg m/s2.
