What could make G become negative at a given enthaply and entropy?
Changing the temperature. my only explanation is I got it right so I hope this helps.
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)

How is the body able to counteract the effects of entropy?
If entropy is taken to mean the amount of "randomness," then you could fight it by organizing matter (e.g. clean up your room). But in time, everything tends towards disorder; entropy increases.
How could one atom become positive and and another become negative?
Ions (atoms that have lost or gained electrons) can make an atom become positive (a cation) or negative (a anion). When an atom loses an electron it becomes positive since there are more protons (positively charged particles) than there are electrons (negatively charged particles) at that point. When an atom gains an electron it becomes negative because there are more electrons than are protons at that point.
What could make G become negative at a given enthalpy and entropy?
Changing the temperature
What could make Delta become negative at a given enthalpy and entropy?
The equation for ∆G is ∆G = ∆H - T∆S H is enthalpy and S is entropySo, ∆G is negative if T∆S is greater than ∆H

Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.

What is the relationship between entropy and energy?
In thermodynamics, entropy is a measure of the non-convertible energy (ie. energy not available to do work) inside a closed system. The concept of free energy involves tapping into an inexhaustible source of energy available to do work. Thus, in a system generating free energy, entropy would never increase, and the usable energy could be siphoned off forever. This illustrates, succinctly, why a free energy system can never exist.
What else could exothermic and endothermic reactions be used?
They could be used for making science test or other things, per example: Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.
When you add a positive and a negative what does it become?
the answer could be negative or positive depending on whether the negative number you're adding is bigger than the positive number

When oxidation number positive or negative?
It could be any thing. It is different to elements.
What is stress response?
It could be negative if it goes on for along time. A person could also become depressed. But stress response could also be positive.
