Pathogenic bacteria isolated from the respiratory or intestinal tracts of humans are

a) strict aerobes that grow best in candle jars.
b) capnophiles that grow best in carbon dioxide incubators.
c) facultative anaerobes that require reducing media for growth.
d) strict aerobes that grow best in reducing media.
e) capnophiles that prefer highly oxygenated growth conditions.

Oxygen and hydrogen gas are at the same temperature t.what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

What happens when you slowly pulled the carboard?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
