Problem- Write the steps in the mechanism for the acid-catalysed esterification of ethanoic acid with propanol.
Rework your solution from the beginning and check each step carefully.
Calculate the equilibrium concentrations of all reactants and products at equilibrium and find the percent by mass of hydrogen gas of the gaseous reaction mixture at equilibrium.
Explain how many ATP molecules are necessary to pump 100 K+ ions out of a cell when the cytoplasmic concentration of K+ is 5 mM the extracellular concentration 150 mM and the membrane potential is constant - 60 mV
The water as well as calorimeter is at 25 Celsius. The graphite is ignited as well as burned and the water temperature rises to 28.05 Celsius. The heat capacity for the calorimeter is 5.15KJ/C. Compute DeltaH per MOLE of the reactant for this reac..
2Na + 2H2O ----> 2NaOH + H2 . If 7.2g of Na undergoes reaction with water and the resulting hydrogen is bruned in oxygen to produce water, how many grams of water would be produced
If a 0.10mL volume of oil can spread over a surface of water of about 32.0m^2 area, calculate the thickness of the layer in centimeters. Enter your answer in scientific notation.cm?
[BrO- ]initial is 0.86 M. 65 seconds later [BrO- ] is 0.19 M. What is the rate of change of [BrO- ] in M/s? (The brackets, [ ], indicate concentration, that is, molarity (M) or moles/liter.)
This question has been asked several times and there appaer to be two different answer and no clear answer on who is right. (One response says the answer is wrong) Calcutlate E red involving Pd
From the values of delta H and delta S, predict which of the following reactions would be spontaneous at 25*C:
If the recorded value of the unknown sample in her lab report was 22.5 g, what was the actual value of the sample
Describe the apparent relationship between H30+ and OH- concentrations when an endpoint is reached in an acid-base titration.
Draw the structure of an alkane or cycloalkane that has more than three but fewer than ten carbon atoms, and only primary hydrogens.
Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3 or 1.00 g/mL) as water, calculate the heat (in J) transferred to the surroundings, qsurr
