b.99.73
c.86.13
d.55.56
2)What is the total pressure of gas in a propane tank if propane has a partial pressure of 22.4 atm, nitrogen’s is 0.44 atm, and oxygen’s is 0.19 atm and methane at a partial pressure of 2.86atm?
a.25.89
b.18.91
c.22.26
d.28.33
3)The earth's atmosphere is composed of 78% nitrogen, 21% oxygen, 0.9% argon, and 0.1% traces of other gases. If the total pressure right now is 101.3 kPa, what is the partial pressure of nitrogen
a.23.3 kPa
b.21.273 kPa
c.91.17 kPa
d.79.014 kPa

its going to be mutualism cuz they both benefit from the relationship.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
