Plot the normalized particle in a box wavefunctions for an electron in a box of 1210 pm for n=1-6 on the same plot. Are any patterns evident? what is the probability of finding an electron in the middle 605 pm for n=6
Nylon is a synthetic polymer made up of amide linkages formed when a diacid condenses with a diamine. The different types of nylons are identified by the number of carbons possessed in the diamine
The following arrangement of flasks is set up. Assuming no temperature change and no chemical reaction, determine the final pressure inside the system after all stopcocks are opened and equilibrium is reached. The connecting tube has no volume. 1s..
When equilibrium is reached at 700C, the total pressure of the system is found to be 4.00 atm. If the equilibrium constant Kp for this reaction is equal to 1.52,
A solution is prepared from 4.5729g of magnesium chloride and 43.244g of water. The vapor pressure of water above this solution is found to be 0.3628atm at 348.0 K. The vapor pressure of pure water at this temperature is 0.3804 atm.
What is the initial concentration of the Fe2+(aq) solution?
Several significant signals have been identified on the spectrum. Assign these signals to corresponding functional groups in the molecule of aspirin
What would happen to the melting point if this unknown were mixed with (a) an equal quantity of pure acetanilide. (b) an equal quantity of benzoic acid
Label the anode, cathode and direction of e- flow an write the half reaction equation for each electrode
If the pH of such a phosphate-containing solution were gradually lowered by addition of HCl or some other strong acid, what three protonated phosphate species would be generated? (Specify the chemical formula and name of each.)
A solution is made by mixing 42.0 mL of ethanol, C2H6O, and 58.0 mL of water. Assuming ideal behavior, what is the vapor pressure
Aspirin (acetylsalicylic acid) is a weak monoprotic acid. To determine its acid-dissociation constant, a student dissolved 2.00 g of aspirin in 0.600 L of water and measured the ph . What was the ka value calculated by the student if the ph of the..
A 100.00 mL buffer solution is 0.175 M in HClO and 0.150 M in NaClO. What is the pH after addition of 85.0 mg go NaOH?
