If the initial number of moles of gas (a combination of H2, H2O and CO2) is 5.45 moles and we add 1.68 moles of the same gas into the experimental chamber then the volume increases to 159.7 L. What was the initial volume of the system?

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

the ratio of the conjugate base to the acid required to attain the desired ph.
