What type of chemical absorbs energy?
The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.
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 the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
What is stored molecular energy called?
Energy stored in chemical bonds of molecules is referred to as chemical energy.This is known as 'enthalpy'.The type of energy that is stored in a molecules bonds is potential energy. This energy can also be called bond energy.It is important to know the different kinds of energy. Potential energy is the energy that is stored in chemical bonds.
What energy is required to begin a chemical reaction?
Your answer is asked on a too broad spectrum. A brief explanation: A chemical reaction is a reaction where certain molecules are reformed to other molecules. To split Water (H2O) into H2 and O2, it needs to be heated to 1800 C, requiring approximately 7524 Kj. However; Sodium (Na) is an alkaline metal, which produces a chemical reaction when it merely touches air or water. PS: Water is more often split with electrolyse (with electricity) than with thermolyse The general sort of energy required is the activation energy. Which can be all kinds of energy.
What is the four kinds of energy?
Four kinds of energy are:1. Mechanical energy2. Chemical energy3. heat energy4. Light energy
What reaction gives out heat and other kinds of energy?
Endothermic
What do you call two or more different kinds of atoms joined together by a chemical reaction?
When more than one atom is joined together by a chemical reaction, the result is called a chemical bond which holds together molecules and the strength of the bond depends on the atoms or the reaction. ---------------------------- A molecule.
Why is chemical energy the energy that is converted to thermal energy?
Various kinds of energy may be converted into thermal energy.In a fire it is chemical energy that is converted to thermal energy.However:In a nuclear reactor, nuclear energy is first converted to thermal energy, and eventually to electrical energy.In a fire chemical energy is also converted to light energy.In a battery chemical energy is converted to electrical energy.In braking systems kinetic energy is converted to thermal energy.
What are Two main kinds of changes that you can observe when chemical reaction occur?
a precipitate is a solid that forms during a chemical reactions
Describe energy in an exothermic reaction?
In an exothermic reaction, energy is released to the surroundings in the form of heat. This results in a decrease in the overall energy of the system, as the reactants have more energy than the products. Exothermic reactions typically feel warm to the touch and can sometimes involve the emission of light.
What are some kinds of potential energy?
Energy stored in a spring; gravitational potential energy; chemical energy; nuclear energy.
