Carbon dioxide is the atmospheric compound that is
responsible (after it have dissolved in water) for both the general acidity of
normal rainwater and the acidity of much soil. Natural rain water is slightly
acidic because carbon dioxide combined with water in the air forms carbonic
acid, which is a weak acid.
Answer:
45.13 psi
Explanation:
Assuming the volume does not change
P1/T1 = P2/T2 T must be in Kelvin
40/(273.15) = P2/(273.15 + 35) P2 = 45.13 psi
Answer:
The moons gravitational pull on Earth
