Draw the major product that is formed when 2-butyne is treated with an excess of hydrogen gas and a platinum catalyst.
Why did the book suggest using a Hirsch funnel? What would be the benefit of using a Hirsch funnel?
The equation for the combustion of acetone is: 2 C3H6O + 8 O2 ---> 6 H2O + 6 CO2 + 852.6 kcal How much heat will be given off if 0.87 mol of acetone is completely burned?
Explain how the mass of a single atom in an element (jn amu), the mass of one mole of atoms of that element
What is the synthesis for the following compunds from simple organic precursors? Make sure the starting sturcutre is a simple organic precursor
A weak monoprotic acid is exactly neutralized by 11.17mL of a standardized 0.1455M NaOH solution. If the Ka of the acid is 0.00084, what is the pH at the half-equivalence point.
Compounds with nearly identical molar masses often have very different physcial properties. Choose the compound with the lower value. Solubility in water: di-ethylether or 1-butanol. Why is it lower?
After completing the calculations below, sketch the pH curve for the titration of 20.0 mL of 0.200 M solution of a weak base, B (Kb = 1.9 x 10^-5), with 0.200 M HBr. Indicate the pH at (a) the beginning of the titration
