A sample of helium gas has a volume of 900. milliliters and a pressure of 2.50 atm at 298 K. What is the new pressure when the temperature is changed to 336 K and the volume is decreased to 450. milliliters?
the volumes in the buret and the flask are identical, and the concentration of the acid in the buret is 1.00 M. If the entire volume of the buret is required for titration of the base in the flask, what is the concentration of base?
You have proven sulfanilamide is capable of forming a stable and selective crystal lattice. Draw additional molecules of sulfanilamide and hypothesize the intermolecular interactions that are most important for providing a stable and selective cry..
Although glucose is a more complicated molecule than CO2 and H2O, there is enough entropy in the O2 products to make the reaction generate entropy overall.
suppose that 1.15 g of rubbing alcohol (C3H8O) evaporates from a 65.0 g aluminum block. If the aluminum block is initially at 25 C, what is the final temperature of the block after the evaporation of the alcohol?
