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.
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 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.
What are some characteristics of chemical energy?
Chemical energy is a form of potential energy stored in chemical bonds. It is released during a chemical reaction, such as combustion. Chemical energy can be converted into other forms of energy, such as thermal or mechanical energy.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
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
Is energy always given out when a chemical reaction takes place?
Yes.
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.
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 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.
What is a negative Gibbs free-energy value an indication of?
A negative Gibbs free-energy value indicates that a reaction is spontaneous, meaning it can proceed without requiring external energy input. It suggests that the products of the reaction are more stable than the reactants at the given conditions.
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.
