Butane (c4h20) burns completely with 110% of theoretical air entering at 74°f, 1 atm, 50% relative humidity. the dry air component can be modeled as 21% o2 and 79% n2 on a molar basis. the combustion products leave at 1 atm. step 1 for complete combustion of butane(c4h10) with the theoretical amount of air, what is the number of moles of oxygen (o2) per mole of fuel? the tolerance is +/-2%

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.
