Problem- What is the final temperature (in C) of a 45g sample of zinc (s=.388J/gK) which evolves (-10.33)J of heat when it cools from 90.2C?
Illustrate structures to prove your interpretation.
If some air remained in your syringe along with the natural gas sample, would that make your result greater or less than the actual molar mass of natural gas? is the same true for your sample of unknown gas?
a gas has a volume of 10 l at 0 degrees c. what is the final temperature of the gas in c if its volume increases to 27
