Oxygen gas most closely exhibits ideal behaviour under conditions of (high/low) temperature and (high/low) pressure.
Taking into account that standard pressure is about 100 kPa, what would happen to the amount of oxygen available to cells if the chamber pressure had a pressure of 120 kPa? The oxygen level in the cells would (increase/decrease) by about 20% because the same amount of oxygen would take up 20% (less/more) space.
what type of salt does copper oxide produce?
A goose is flying south for the winter at a constant speed. Keep in mind that one mile is 1.61 km, and one pound is 454 g.
