Calculate the compression ratio (final/ inital volume) required to raise the temperature of air, initally at 1 bar and 300K to 900K. What is the final pressure? Air can be considered an ideal gas with Cv = 5R/2 at all conditions of interest.
where the atmospheric pressure is 1.00 atm. The balloon rises to an altitude of 20,000 m, where the atmospheric pressure is 61 mmHg and the temperature is 210 K. What is the volume of the balloon at 20,000 m?
What is the sum of the stoichiometric coefficients when the reaction is balanced to lowest common denominator
enzyme1 (E1) is required to convert reactant B to product C. Enzyme 2 (E2) is required for the reverse reaction (C to B). The activity of E1 is 50 pmol of C created/10^6 cells *s and that of E2 is 40 pmol of B created/10^6 cells*s.
