in the 1H NMR spectrum for ethanol, we expect to have peaks (enter number of peaks), with an integration ratio of (enter integration ratio).The farthest downfield peak is for the hydrogen(s) attached to the (enter atom the Hydrogen is attached) in the group (enter chemical formula for the group). The most shielded peak is for the hydrogen(s) attached to the (enter atom the Hydrogen is attached) in the group (enter chemical formula for the group).

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.
