At the same pressure, about 25 times more co2 will dissolve in plasma as o2. why does this occur?

The twister and runaway train are two coasters at the same amusement park. both coasters start at the same height. the coaster for the twister is twice the mass of the coaster for the runaway train. which roller coaster has greater gravitational potential energy at the start of the ride?

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).

Due tomorrow which would have a lower ph, a 0.1 m solution of a strong base or a weak base? why? which would have a higher ph, a 0.1 m solution of a strong base or a weak base? why?
