Answer:
A Chemical Reaction
Explanation:
There are 2 kinds of reactions physical and chemical. The digestion process often involves the use of digestive enzymes in your mouth and acid in your stomach.
2 - PE of products-PE of reactants.
You are trying to calculate the energy change that occurred from the start of the reaction (the reactants going in) to the end of the reaction (the products coming out). Therefore if there is more energy at the end, you will get a positive result from subtracting the PE of the reactants, and vice versa.
<span>First we write the reactants and the products in this manner shown below:
C5H12 + O2 = H20 + CO2
This equation is not yet balanced so we add coefficients to make the equation balance:
</span><span>C5H12 + 8O2 = 6H20 + 5CO2
</span>
The principle of concern here is the Law of Conservation of Mass.
<span>This law states that for a system that is isolated, the mass is not created nor destroyed. Hence for this system, the amount of CO2 and water created is exactly from the reactants pentane and oxygen.
