Determine the point group for each of the three possible geometries of the hypothetical Be3+ ion, then draw the molecular orbitals for each geometry, using the 2s orbitals as a basis set. Give the expected ground state for each geometry.
What is the percent yield if 5g of anthracene-9-carbaldehyde (MW= 206.24) is used to make 4.8g of 9-strylanthracene
a 130g piece of metal is heated to 286C and dropped into 87.0g of water at 26C, if the final temperature of the water is 58.3C.
Assume you have a solution containing two volatile liquids. Given the data for liquid A: MM = 56.89 g/mole, partial pressure = 0.903 atm and for liquid B: MM = 14.52 g/mole, partial pressure = 0.995 atm
A 0.456 gram sample of an unknown mono protic acid (let's call it HZ) was dissolved in some water (you pick the amount). Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
A half-life of phosphorus-32 =14.0 days. starting with six grams of 32P, determine how many grams would remain after 112 days

Identify which will be warmer if you heat equal masses of gold and iron starting at room temperature with 1 kJ of energy
The excess I3- was titrated with 50.00 mL of a 0.02000 M Na2S2O3 solution. What was the mass percent of arsenic trichloride in the original sample?
Estimate the mass of water that must evaporate from the skin to cool the body by 0.50^circ C. Assume a body mass of 85 kg and assume that the specific heat capacity of the body is 4.0 {rm{J}}/{rm{g}}; cdot ;^circ {rm{C}}.
At 50 degrees C, the value of pKw (the dissociation constant for water) is 13.262. Calculate the pH of water at this temperature.
