If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Why do endothermic reactions need additional energy to keep going while exothermic reactions don't?
Ipso facto. An endothermic reaction "absorbs" energy (uses it to create high-energy bonds), so this must be constantly supplied from an external source. An exothermic reaction "releases" energy, and this energy can be used to continue the reaction until there are no reactants remaining.This is why stellar cores cannot fuse massive quantities of elements heavier than iron. The reactions are not self-perpetuating as they are absorbing energy rather than releasing it. A large, inert iron core is the result.
Why respiration is considered an exothermic reaction?
An exothermic reaction is one in which heat or energy is released, and that occurs in respiration. That is how the body uses respiration -- to get energy. If it were an endothermic reaction we would need to put energy into the process and not get energy out.
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
When a cell uses chemical energy to perform work it couples a reaction with a reaction?
When a cell uses chemical energy to perform work, it couples an exergonic (energy-releasing) reaction with an endergonic (energy-requiring) reaction. This coupling allows the cell to harness the energy released from the exergonic reaction to drive the endergonic reaction, enabling the cell to perform work such as transport, mechanical movement, or synthesis of molecules.
What happens to energy in an endothermic reaction?
An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.
What is A reactant in which energy is taken in?
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy
How does endothermic reactions affect room temperature?
Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature in the room where the reaction takes place. This can make the room feel cooler as the reaction uses up the heat energy present in the environment.

Is evaporation os exothermic or endothermic process.explain?
Physical endothermic change because it uses energy (taking up heat)

Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
Is exercise of a body an exothermic and endothermic?
As you exercise your body uses stored fuel and turn it into energy to power mechanical movement. In this process, energy in the form of heat is released in to the surroundings. Therefore this is an exothermic process.
If a chemical reaction uses up energy the reaction is .?
endothemic
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
An internal combustion engine uses what kind of energy to do work?
it uses kinetic energy (movement) and a chemical reaction.
