after finding the kinetic trace by bleaching food dye and finding the concentration and then graphing.
A student following the procedure in this experiment prepared three solutions by adding 11.50, 23.00, and 34.50 mL of a 7.60 x 10-2M NaOH solution to 50.00 mL of a .112M solution of a weak acide.
describe an experiment using only hot and cold water that would allow you to verify that the heat capacity of your coffee-cup calorimeter
A 1.80 M solution of 56 ml is diluted to a volume of 218 milliliters a portion of that solution of 109 milliliters is diluted using 149 milliliters of H2O. determine the final concentration of this solution
the specific heat of ethylene glycol is 2.42 J/g-K. How many J of heat are needed to raise the temperature of 62.0 g of ethylene glycol from 13.1 C to 40.5 C ?
A 4.78 g sample of aluminum completely reacts with oxygen to form 6.67 grams of aluminum oxide. Use this date to calculate the mass percent composition of aluminum in aluminum oxide.
The barometric air pressure that day was 733 mm Hg. What is the pressure of the vapor inside the flask (in atmospheres) after the vapor had cooled and the students opened the flask momentarily?
Consider the reaction: 2 K(s) + 2 H2O(l) -> 2 KOH(aq) + H2(g), DH = ? The heat released when 24.9g of K reacts with excess water is 124 kJ. Determine the enthalpy change, DH, for the above equation as written
Each of four compounds shown has one signal in the aromatic region and one signal in the alkyl region of its H NMR spectrum. Use the integral values to determine which compound's H NMR spectrum is shown below
describe how sp3 hybridization occurs in each atom. a) carbon b) nitrogen c) oxygen. If these elements use sp3 hybrid orbitals to form bonds, how many lone pairs of electrons would be found on each?
Calculate the mass of air in an air-filled tire. Part B: Calculate the mass of helium in a helium-filled tire. Part C: What is the mass difference between the two?
