Compound j, c16h16br2, is optically active. on treatment with strong base, compounds k and l (each c16h14) are formed; k and l each absorb only 2 equivalents of hydrogen when reduced over a pd/c catalyst. compound k reacts with ozone to give phenylacetic acid (c6h5ch2cooh), while similar treatment of l gives 2 products. one product, m, is an aldehyde with formula c7h6o; the other product is glyoxal (cho)2. draw the structure of compound m.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
