What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
When does heat equal enthalpy in a chemical reaction?
Heat equals enthalpy in a chemical reaction when the reaction is carried out at constant pressure.
Is heat energy always released in a chemical reaction?
No. One example of a chemical reaction which releases something other than heat is gamma radiation, which gives off massless light particles (as hard as that is to believe). In addition, all endothermic reactions actually consume heat energy.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
What is a chemical reaction gives off heat called?
exothermic reactions-gives off heat
What term is used 4 the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
What is the proper name for a chemical reaction that gives out heat?
combustion
During photosynthesis what chemical reaction gives off heat?
During photosynthesis, no chemical reaction gives off heat. Photosynthesis is an endothermic process, meaning it requires energy in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
What phrase best describes a exothermic chemical reaction?
A chemical change that gives off heat. Burning paper would be an example.
What happens to the heat generated by a chemical reaction in a normal non-insulated glass flask?
The heat is released in the environment.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
What is a chemical reaction that's absorbs energy called?
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
