CH4 + 2 O2 → CO2 + 2 H2O
What’s the total energy

80.2114/mol

Explanation:

that is the answer that I got using my chemistry calculator so I hope it works for your question.

Explanation:

An endothermic reaction occurs in a chemical cold pack. If you mix methane and oxygen together, a reaction isn't a straight away reaction. There is a barrier to the reaction. This barrier is due to the fact that to make CO2 and H2O break 4 carbon-hydrogen bonds and some oxygen-oxygen bonds.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

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.
