What was investigated in the lab? Was your hypothesis supported?
Explain why or why not.
Was there ever complete lack of oxygen?
Use evidence to defend this claim
What was the role of photosynthesis in this experiment?
What was the role of cellular respiration in this experiment?
Explain how all living things are dependent on these two processes

I'm assuming this was a burning match situation, and give more than 5 points if you expect people to answer all those questions

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
