Consider the following reaction at equilibrium. what effect will adding 2.3 mole of rn to the reaction mixture have on the system? 2 h2s(g) + 3 o2(g) ⇌ 2 h2o(g) + 2 so2(g) no effect will be observed. the equilibrium constant will increase. the equilibrium constant will decrease. the reaction will shift to the right in the direction of products. the reaction will shift to the left in the direction of reactants.

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.
