Use the van der waals equation to calculate the pressure exerted by 1.000 mol of cl2 in a volume of 5.000 l at a temperature of 273.0 k. then use the ideal gas equation to calculate the pressure. explain why the two values are different. constants for cl2are a

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
