An acid (x) reacts with a base (y) to produce mg3(po4)2. what are x and y? x = h3po3; y = mg(oh)2 x = h3po4; y = mg(oh)2 x = h3po4; y = ca(oh)2 x = h3po3; y = ca(oh)2

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit

what is your question? collegechemistry 5+3 pts 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.
