Propane undergoes combustion with oxygen gas to produce carbon dioxide and liquid water according to the following equation. Balance this equation.
C3H8(g) + O2(g) → CO2(g) + H2O (l)

a. What volume of propane (C3H8) is required to produce .762 L of carbon dioxide gas at STP?

b. What volume of oxygen gas would also be required?

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

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.
