What kinds of energy is given off in a chemical reaction?
nuclear
Energy is given off in the form of heat during a?
exothermic reaction. This type of reaction releases energy to the surroundings as heat.
Energy is given off in the form of heat during a what?
A chemical reaction
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
What is a chemical reaction in which more energy is taken in than given off?
An endothermic reaction is a chemical reaction in which more energy is taken in than given off. This means that energy is absorbed from the surroundings during the reaction, causing a decrease in temperature. An example of an endothermic reaction is the reaction between baking soda and vinegar.
An indication that energy is given off in a chemical reaction is shown by an?
An indication that energy is given off in a chemical reaction is shown by an increase in temperature. This is because the released energy can manifest as heat, causing the surroundings to become warmer.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
Energy is the energy needed to start a chemical reaction?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that reactants must overcome to form products. This energy is needed to break bonds in the reactant molecules before new bonds can form in the products.
When you crush a glow stick and shake it the two liquids mix and the stick glows. Is this a chemical reaction and is energy being absorbed or given off?
In a glow stick a chemical reaction occur; the energy is released.
What is the term for the amount of energy that needs to be added for a chemical reaction to start?
The term for the amount of energy needed for a chemical reaction to start is called activation energy. It is the energy required to initiate a reaction by overcoming the energy barrier between reactants and products.
What is a chemical reaction in which more energy is given off than taken in?
Combustion, burning, releases more heat that is taken in to start the reaction.
What is the name given to the substances at the start of a reaction?
The substances at the start of a chemical reaction are known as reactants. Reactants are the molecules or compounds that undergo a chemical change during the reaction. They are typically written on the left side of a chemical equation, while the products of the reaction are written on the right side. The reactants are consumed during the reaction to form the products.
