α-Linolenic acid ((9Z,12Z,15Z)-octadeca-9,12,15-trie noic acid; ALA)) is a poly-unsaturated, w-3 fatty acid with 18 carbons found in many food sources. Since humans cannot synthesize fats with double bonds past carbon #9, it is "essential" and must be obtained from the diet. If a serving of salmon contains 500.0 mg of ALA and all of it is completely oxidized via β-oxidation and the TCA, how many grams of water at room temperature can be brought to a boil using that energy? (Specific heat of water: 4.184 J/mol; heat of vaporization of water: 40.65 kJ/mol; molar mass of ATP: 507.2 g/mol; DG° of ATP hydrolysis = -30.3 kJ/mol)

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet

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.
