Did a lab in Orgo II where we broke apart dicyclopentadiene with fractional distillation in order to get cyclopentadiene which we used in a reaction after. This lab is focused on Diels-Alder reactions and one of my lab questions says " Explain why dimerization of the cyclopentadiene is the side reaction and discuss how to avoid this side reaction.
The heat of solution of ammonium chloride is 15.2 kJ/mol. If a 6.253 g sample of NH4Cl is added to 65.0 mL of water in a calorimeter at 26.9°C.
particular sample of pure iron requires 0.595 kJ of energy to raise its temperature from 25oC to 45oC. The specific heat of iron is 0.45 J/g oC. What must be the mass of the sample?
Explain why alcohols such as ethanol and propanol are soluble in water, butanol is moderately soluble and pentanol is slightly soluble
Determine the molar mass of the substance if 120.0 grams of a pure sample contained 24.0 mol of the substance. Express your answer in g/mol.?
The atmosphere becomes colder at higher elevation. As an average the standard atmospheric absolute temperature can be expressed as Tatm = 288 - 6.5 × 10?3 z, where z is the elevation in meters.
Calculate the molar concentration of OH- ions in a 0.550 M solution of hypobromite ion (BrO-; Kb=4.0 x 10^-6). What is the pH of this solution?
The rate of effusion of a particular gas was measured and found to be 24.0 mL/min. Under the same conditions, the rate of effusion of pure methane (CH4) gas is 47.4 mL/min. What is the molar mass of the unknown gas?
Supppose that a 2 L solution is made from 178 mg of citric acid (C6H8O7). What is the molar mass of C6H8O7
The system CO2(g) + H2(g) *) H2O(g) + CO(g) is at equilibrium at some temperature. At equilibrium a 4.00 L vessel contains 1.00 mole CO2, 1.00 mole H2, 2.40 moles H2O, and 2.40 moles CO.
A buffer is made up 0.24 M propanoic acid, CH3CH2COOH, a weak monoprotic acid, and 0.17 M of sodium propanoate, CH3CH2COONa. What is the pH of the solution.
175g of water was heated from 15 degrees to 88 degress celsuis. how many kilocalories were absorbed by the water?
or the reaction H2(g)+CO2(g) H2O(g)+CO2(g) at 700C, Kc=.534. Calculate the number of moles of H2 that are present at equilibrium
