The chemical reaction is expressed as:

2H2 + O2 = 2H2O

To determine the amount of oxygen used in the reaction, we use the amount of water produced and the relation of the substances in the reaction we do as follows:

209 g H2O ( 1 mol / 18.02 g ) ( 1 mol O2  / 2 mol H2O ) ( 32 g / 1 mol ) = 185.57 g O2

According to the concept of the tragedy of the commons, what happens to shared resources over time?
Maslowich
I would believe the answer to this question is D. According to the concept of the tragedy of the commons, shared resources are used by more than one organism. Due to the large consumption of shared resources they start to be fewer and fewer in number and over time if we are not careful they will be depleted.
