Calculate the number of moles of cyclopentadiene and maleic anhydride which you will use in your experiment. Explain why we use excess of cyclopentadiene and do the reaction at 0 °C?
Write a balance equations for both half-reactions for the redox. combine them to determine the overall balanced
Determine what is the density of the oxygen gas in the full bottle If A cylindrical gas lecture bottle has internal dimensions of 18.0 cm in diameter and a height of 49.0 cm and weighs 1.75 kg when empty.
if a sample of the compound contains 9.41x10^21 lithium ions, how many oxide ions does it contain? show units, show work and answer in scientific notation.
Determine the characteristic wavelengths if an electron are accelerated through an electric potential to a kinetic energy of 18kev.
What organic product(s) is formed when 1-methylcyclopentanol is heated in the presence of an acid catalyst?
Calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant
H2S (aq) is a polyprotic acid, meaning it can dissociate its hydrogen ion more than once. However, HS- (given its negative charge as well as its extra hydrogen ion) can act as either a base or an acid
What is the pH of 1.0 x 10^-4 M phenol where ka = 1.3 x 10^-10? This is a weak acid under dilute conditions. You need to take into account water self-dissociation to find the hydronium concentration.
The work function of copper is 437 kj/mol. Calculate the KE of the ejected electron if the frequency of light is 1.50*10^(15) Hz.
Calculate the standard cell potential and equilibrium constant at 25 C for the cell reaction in a direct methanol fuel cell. 2CH3OH (l) + 3O2 (g) --> 2CO2 (g) + 4H2O (l)
What is the minimum distance that the moving mirror in the FTIR instrument must transit to resolve these two resonances?
The reaction 2NO(g) + Cl2 (g) -> 2NOCl(g) is carried out in a closed vessel. If the partial pressure of NO is decreasing at the rate of 21 torr/min, what is the rate of change of the total pressure of the vessel?
