Help please, just mind the fact that I have an X on something that was on accident and forget the evidence cards that I have it’s probably incorrect. I need to know which evidence cards support which claim and the reason. Claim 1: There is frozen water in tank 2, which is blocking some of the oxygen from going into tank 3.

Claim 2: Some of the liquid oxygen evaporated in tank 3.

Claim 3: Some of the oxygen didn’t condense in tank 2.

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.
