What does a Maxwell-Boltzmann distribution illustrate?
What does a Maxwell-Boltzmann distribution illustrate? The Maxwell-Boltzmann distribution describes the distribution of speeds among the particles in a sample of gas at a given temperature. The distribution is often represented graphically, with particle speed on the x-axis and relative number of particles on the y-axis. Created by Sal Khan.

How is aspartate Transcarbamoylase regulated?
How is aspartate Transcarbamoylase regulated? Regulation of De Novo Pyrimidine Biosynthesis In prokaryotic cells aspartate transcarbamoylase, an allosteric protein, is inhibited by the end product CTP and activated by ATP. Why is it important to regulate ATCase? The cell must precisely regulate the amount of CTP in the cell because making it can be energetically […]
How do you calculate the pressure of hydrogen gas collected over water?
How do you calculate the pressure of hydrogen gas collected over water? To obtain the gas pressure, subtract the vapor pressure of water from the total pressure. EXAMPLE: A 325 mL sample of gas is collected over water at 26oC and 742 mm Hg pressure. Calculate the volume of the dry gas at STP. The […]
