Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
Is baking bread a endothermic and exothermic?
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
When iron rusts is it an endothermic or exothermic reaction?
It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen
When sodium hydroxide is added to water the reaction is endothermic or exothermic?
The reaction of sodium hydroxide with water is exothermic, meaning it releases heat energy. This is because the process of dissolving sodium hydroxide in water releases energy in the form of heat.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
What happens when dilute sulphuric acid is added to zinc granules . Is it an exothermic or an endothermic reaction?
When dilute sulfuric acid is added to zinc granules, a displacement reaction takes place, resulting in the formation of zinc sulfate and hydrogen gas. This reaction is exothermic, which means it releases heat energy.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
If rubidium is added to water will it be endothermic or exothermic?
The reaction between rubidium and water is highly exothermic, leading to the spontaneous production of hydrogen gas and the formation of rubidium hydroxide. This exothermic reaction is typically very vigorous and can even result in the ignition of the hydrogen gas produced.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
When solid sodium hydroxide is added to water the solution gets hot is this endothermic or exothermic?
When solid sodium hydroxide is added to water, the process is exothermic because it releases heat. The heat is generated as the sodium hydroxide dissolves in water, and the surrounding environment experiences a temperature increase.

Is fractional distillation of oil a process of exothermic?
No, fractional distillation of oil is not an exothermic process. It is a physical separation process that relies on the differences in boiling points of the components in the crude oil mixture. Heat is added to vaporize and separate the components, making it an endothermic process.
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
