Find the average value of the electron-nucleus seperationin a hydrogen like atom in the 2pz (ml=0) state. Having difficulty simplifying at the end, and understanding where the equation goes towards infinity.
A solution is made by mixing 12.0g of NaOH and 70.0mL of 0.200m HNO3. Calculate the concentration of OH- ion remaining in the solution.
KOH are diluted to 1L to give the same species produced by Al(OH)3. Write mass balance equations for aluminum and potassium.
calculate the maximum number of moles, liters and grams of H2S that can form when 187 g lead sulfide reacts with 140. g water at 29.0 °C and 0.75 atm of pressure.
Initial concentration of CH3NC is 0.0340M. How many minutes does it take for the CH3NC concentration to drop to 0.0300M?
Suppose that Mt=Lt=0.1M (exactly) and the pH is somehow fixed at 5.00. (This means that the charge balance no longer applies.) Use the equilibria and the two mass balances to find the concentrations of ML+, M+2, L-, HL.
Consider the sublimation of mothballs at 27 C in a room having dimensions 7.5ft x 11.0ft x 7.1ft. Assume that the mothballs are pure solid naphthalene (density 1.16 g/cm3) and that they are spheres with a diameter
At atmospheric sample is composed of nitrogen, oxygen, argon, water vapor, and trace other gases. If the partial pressure of nitrogen is 577 mmHg, oxygen is 148 mmHg, water vapor is 20 mmHg and argon is 7 mmHg, what is the observed barometric pres..
What is the minimum volume of 2.6 M HBr required to completely dissolve 25.0 g of potassium metal?
Titrated with 0.10 M HBr. Determine the pH of the solution after the addition of 400.0 mL HBr.
Glucose is approximately .10 % of human blood, by weight. Glucose has a formula weight of 180 g/mol. What is the conc of glucose in ppm
usually some inception time is involved during the preparation of the Grignard. Explain the reason behind
Nitrogen (N2) reacts with hydrogen to give ammonia (NH3): N2 + 3H2 -> 2NH3 If 30 g of N2 reacts with excess hydrogen, what the mass of ammonia formed would be?
