Why is it important that the sun uses fusion to produce energy and not chemical reaction?

There just isn't enough oxygen up there to support a fire that size. Add to this that a normal chemical fire would just not get hot enough to put out the heat that the sun does. We are able to measure the radiation from the sun. Then there would be the question that asks where was the fuel grown that feeds the fire that is the sun, and how did it grow on a planet as big as the sun before it started burning.

∙ 14y agoIf the Sun were composed entirely of, let's say, methane, and radiated heat by combustion of this methane with oxygen, the Sun would only be able to radiate energy for about 3000 years (at its current rate). In other words, if the Sun produced energy by chemical reactions, then it would just be a giant ball of cold carbon dioxide and water vapor by now.
The Sun actually emits energy released from nuclear fusion which occurs deep in its core. These nuclear reactions release much much more energy, so the Sun will be around for billions of years to come (I hope).

Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
Does an exergonic reaction become hot?
An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic). An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic).
Is it possible for a cell to harvest all of the energy contained within a chemical reaction to produce movement?
no.
Why is wood burning chemical energy?
how chemical energy produce in firewood useful
What occur in a chemical reaction and why are chemical reaction important?
This is the energy needed to get us from our starting point to the top of the hill would be the activation enery

What is a chemical reaction is endothermic?
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
Can energy be realesed during a chemical reaction?
yes the whole point of a chemical reaction is to produce some type of energy like in a battery
Does an exergonic reaction become hot?
An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic). An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic).
How do oxygen produce energy when there no light?
Through oxidation. That is to say, a chemical reaction that involves oxygen.
Is it possible for a cell to harvest all of the energy contained within a chemical reaction to produce movement?
no.

What is the primary reason why chemical bonds form?
for energy:) The major reason for chemical bonding is to produce energy. As a reaction occurs and begins to form products at a lower energy, energy must be released.
What is a chemical reaction in which energy is absobed?
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
When cells breakdown a sugar molecule to produce chemical energy?
A chemical reaction that happens in every cell to break down sugar
Chemical reaction that produces heat?
Chemical reactions that produce heat (or energy) are known as Exothermic Reactions. (Example: combustion of fuels)
