A20.69 g sample of impure magnesium car- bonate was heated to complete decomposition according to the equation mgco3(s) → mgo(s) + co2(g) . after the reaction was complete, the solid residue (consisting of mgo and the original impurities) had a mass of 17.48 g. assum- ing that only the magnesium carbonate had decomposed, what was the percent of magne- sium carbonate in the original sample? answer in units of %.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)

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.
