A gas occupies 275ml at 0 degree celcius and 610 torr. what final temprature would be required to increase the pressure to 760 torr. the volume being held consyant?
Tf will be negative and so you must use negative Kf values. Either way, the freezing point of the solution should be lower than that of the pure solvent. Assuming 100% dissociation, Find the freezing and boiling points of 1.85 m Na2SO4(aq).
A cook wants to heat 1.75 of water from 26.0 to 100.0 If he uses the combustion of natural gas (which is exothermic) to heat the water, how much natural gas will he need to burn? Natural gas produces 49.3 of heat per gram.
Why is glycogen debranching enzyme necessary? a) It allows regulation of the rate of glycogenolysis. b) Because glycogen phosphorylase cannot convert G1P to G6P
