Write the electron configurations for P and Cl using both the spdf notation and orbital box diagrams. Describe the relationship between each atom's electron configuration and its position in the periodic table.
a mixture of methane and water vapor pressure is passed over a nickel catalyst at 1000k. the emerging gas is collected
the flask was filledto the calibration mark with water. What were the equilibrium concentrations of H3PO4,H2PO-, HPO-2, PO-3, and H+ in the resultant solution. Ka1 = 7.1x10-3, Ka2 = 6.3x10-8, and Ka3 = 4.2x10-13 for H3PO4.
Calculate the molarity of a solution of 25.2mL of methanol combined with enough water to make 622mL of solution (density of methanol is 0.79180g/mL).
A quantity of 18.68 ml of a KOH solution is needed to neutralize 0.4218g of a KHP what is the concentration of the KOH solution
German physicist Werner Heisenberg related the uncertainty of an object\'s position (?x) to the uncertainty in its velocity ?v.The mass of an electron is 9.11× 10-31 kg.
Which has the larger hydration energy, AL+3 or Li+ (Both ions are about the same size)
Just transfer this solution completely to a flask of 1L volumetric and dilute to exactly 1 liter and then compute the Fe 2+ ion concentration.
What is the pH of a solution containing 0.10 L of 0.10 M acetic acid, to which 0.010 moles of acetate are added. Volume does change in this case. Density of the acetate salt is 55.05 g/mL
A 25.0 mL sample of a 0.115 M solution of acetic acid is titrated with a 0.144 M solution of NaOH. Calculate the pH of the titration mixture after 10.0, 20.0, and 30.0 mL of base have been added.
The energy levels the electron can occupy in the He^+ ion can be calculated using the energy level equation. Calculate the energy in kJ/mol of the electron when it is in the n=5 level. Energy level equation
At 1000K, the equilibrium constant Kc for the reaction is 3.80x10-5. Suppose you start with 0.0356 of I2 in a 2.30 L flask at 1000K. What is the concentration of the atomic gas at equilibrium
