2. A 150. gram sample of an unknown metal went from an initial temperature of 22.4 C to a final temperature of 12.6 C. The sample underwent a change in thermal energy of -662 J. If the sample is one of the metals listed in the table above, what is the identity of the metal

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.
