Classify the reaction endothermic or exothermic and give the change in enthalpy of the reaction. 2 SO3 (g) → 2 S (s) + 3 O2 (g)

ΔH = 632 kJ

The heat energy in the reaction is
absorbed or released.

This makes the reaction
exothermic or endothermic.

So, the energy would be on the
reactant or product
side.

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.
