The boyle temperature is the temperature at which the coefficient b is zero. Therefore, a real gas behaves like an ideal gas at this temperature. (a) Give a physical interpretation of this behavior.
A rigid plastic container holds 1.00 L methane gas at 630 torr pressure when the temperature is 20.3°C. How much more pressure will the gas exert if the temperature is raised to 44.3°C?
The nitrogen in a 4-tablet sample that weighed a total of 7.50 g was converted to ammonia by Kjeldahl digestion, followed by distillation into 100.0 mL of 0.1750 M HCl. The analysis was completed by titrating the excess acid with 11.37 mL of 0.108..
Derive the rate law expression for the chlorination of vinyl chloride based on this mechanism.
Methyl Orange is an acid-base indicator. In dilute solution, at pH greater than 4.4, it is yellow. At pH=3.2 the solution appears red. Draw a structure of the species that is formed at the lower pH of the acid proton adds to the azo nitrogen atom ..
