What phrase best describes a exothermic chemical reaction?
A chemical change that gives off heat. Burning paper would be an example.
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.
What is a heat reaction?
This the heat released during a chemical reaction.
Is it true that Every chemical reaction gives off energy?
yes it does <><><> No- some reactions ABSORB energy. In terms of heat energy, some are exothermic, and some are endothermic.
Heat of reaction for a chemical reaction symbol?
The symbol used to represent the heat of reaction in a chemical equation is ΔH. It indicates the enthalpy change of the reaction, which is the heat exchanged during a chemical reaction at constant pressure.
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 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.
What is a chemical reaction that happens in home and gives heat?
Burning wood in a fireplace is a common chemical reaction that produces heat. This involves the combustion of wood, where oxygen from the air reacts with the wood to release 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.
What is the relationship between the heat of reaction and the chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction. It is a measure of the energy change that occurs as reactants are converted into products. The relationship between the heat of reaction and the chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat).
