Why was residual dichloromethane boiled off prior to filtration off the acidified mixture?this is in regards to an experiment with mixed Aldol condensations of benzaldehyde and acetone.

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?

1) this is the structure in the cell nucleus that houses a cell's genetic information

The continuous release of nuclear energy caused when one fission reaction triggered more nuclear reactions is a
