The amount of heat produced in a reaction is not fixed. It depends upon the total amount of energy change that has taken place in the reaction altogether.

Not only this, all reactions do not produce heat. In some cases we have to supply energy from external sources to get the reaction started.

What is called the ability to produce heat and light in a chemical reaction?

The ability to produce heat and light in a chemical reaction is called combustion. It is a type of exothermic reaction where energy is released in the form of heat and light.


Where does the sun produce heat?

From the nuclear reaction of burning hydrogen!


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.


Magnesium reacts with oxygen gas to produce magnesium oxide light and heat this reaction is?

The reaction between magnesium and oxygen gas to produce magnesium oxide is a combustion reaction. Combustion reactions are exothermic, producing light and heat as they release energy in the form of heat.


What type of reaction is taking place when Butane burns to produce a flame?

The combustion of butane to produce a flame is a chemical reaction known as a combustion reaction. In this reaction, butane reacts with oxygen to produce carbon dioxide, water, and heat energy.


How does fluorine and cesium produce heat when they are combined with each other?

This is an exothermic reaction.


A reaction occurs when a substance reacts with oxygen to produce energy in the form of heat and light?

The reaction you are describing is likely combustion, which is a type of chemical reaction where a substance combines with oxygen to produce heat and light. This process is exothermic, meaning it releases energy in the form of heat and light. Combustion is a common reaction in processes like burning fuels.


What is a chemical reaction that absorbs heat?

An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.


What kind of animal does not produce much internal heat?

Cold-blooded animals do not produce much body heat. Most do not produce any at all.


Are glow sticks an example of a combustion reaction?

No, a combustion reaction is where a chemical reacts with oxygen to produce an oxide and lots of heat. Glow sticks use a a kind of reaction chemiluminescence. The reactions often involve oxygen particularly hydrogen peroxide, but they are not combustion reactions and typically produce little to no heat


Is a hand warmer pack an endothermic reaction?

Exothermic. It release heat in the process.


Is an exothermic reaction will produce heat and will be reabsorbed to increase the rate of reaction?

Have you heard of Haber-Bosch process of production of ammonia. This is an example of the question you asked. If we apply the required heat in the beginning of the reaction we do not need to apply it again as its exothermic reversible reaction and will use the heat to continue the reaction. But the rate of reaction is not increased.
