Determine the symmetry-adapted linear combinations for the molecular orbitals of NH3 using atomic orbitals from the nitrogen and hydrogen atoms.
Excess dietary fat can be converted to cholesterol in the liver. When palmitate labeled with 14C at every odd-numbered carbon is added to a liver homogenate, where does the label appear in mevalonate
If the original sodium tartrate solution had a concentration of 1.00 M instead of .100 M, what would the concentration of copper be in a solution created by combining 10 mL of it with 10 mL of the copper (II) sulfate solution. Use the Ksp you foun..
which hydroxide precipitates first as NaOh is slowly added to the solution? b) what is the molar concentration of the first cation precipitated when the other cation just starts to precipitate out of solution?
Weak acid unknowns with a solution of NaOH of about 0.10 mol/L.
Problem- Hydrogen gas reacts with oxygen gas to form water vapor. If 5.50 g of hydrogen gas react with 10.50 g of oxygen gas, how many grams of water vapor will be produced
Explain if you have an equimolar mixture. If not, discuss how you would achieve equimolar condition. Show calculations if necessary.
Rubidium has two naturally occurring isotopes: Rb-85 with mass 84.9118 amu and a natural abundance of 72.17%, and Rb-87 with mass 86.9092 amu and a natural abundance of 27.83%.
The pH of a 0.40 M HF(aq) solution is 1.93. Calculate the change in pH when 0.356 g of sodium fluoride is added to 50.0 mL of the solution. Ignore any change in volume.
