Prove Conservation of Mass This is the combustion of pentane. How do I prove that there’s a conservation of mass? I can’t find a way to make it add up.

2C5H12O+15O2→10CO2+12H2O

Explanation:

To prove the Law of Conservation of Mass, this equation is not balanced. To balance it, you need to show the work to find out how to balance it. To do that, You look at the C’s first and question are they balanced? They aren’t so you add a CO2 and continue that process until it’s balanced for each element.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
