Energy is what in a chemical change?
In a chemical change, energy is either absorbed or released. When bonds are broken, energy is absorbed (endothermic reaction), and when bonds are formed, energy is released (exothermic reaction). Overall, the total energy of the system may change during a chemical reaction.
What a chemical reaction mean?
A chemical reaction is; when there is a chemical change taking place from energy or shifting of molecular structure.
What happens to energy during a chemical change?
when a chemical change occurs, chemical bonds are broken up
Which variable is not required to calculate the Gibbs free-energy change for a chemical reaction?
The variable that is not required to calculate the Gibbs free-energy change for a chemical reaction is the temperature.
Does a change in energy always occurr during a chemical reaction?
no
What is the chemical change of the sun's energy into glucose and oxygen?
This chemical reaction is called photosynthesis.
What is energy released or absorbed during chemical change called?
It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
Does the amount of energy change during a chemical reaction?
duuh...of course it does
What are the two types of energy change in chemical reaction?
endothermic and exothermic
What would happen if there wasn't enough activation energy in a chemical change?
If the activation energy for a particular chemical reaction was not available the reaction cannot proceed. The chemical reaction cannot proceed without activation energy and cannot form products.
The energy change when reactants are converted to products in a chemical reaction is?
The energy change when reactants are converted to products in a chemical reaction is known as the enthalpy change (∆H). It represents the difference in energy between the products and reactants. Depending on whether energy is released or absorbed during the reaction, the ∆H value can be negative (exothermic) or positive (endothermic).
