It is given that a protein has a molecular weight (Mw) of 21342. It consists of 180 amino acids of which 80 are glutamine (Mw of anhydro residue = 128.1), 60 are histidine (Mw of anhydro residue 137.2) and 40 alanine (Mw of anhydro residue 71.1). At both the C-terminal and the N-terminal position an alanine residue is present.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?
