While cytotoxicity, antiviral activity, and immunosuppressant properties of didemnin-C and of its 8 analogs were excellent to very good, these compounds were, unfortunately, dropped from further studies and development at the stage of human trials..
A sample of gas has a mass of 0.565 . Its volume is 119 at a temperature of 80 and a pressure of 746 . Find the molar mass of the gas.
A sample of an ideal gas at 1.00 atm and a volume of 1.89 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume.
The blood buffer system is made up of H2CO3 and HCO3. Describe with the use of equations how this system responds to added H3O and to added OH.
