What else can I help you with?
What two forms of energy can be released in exothermic reactions?
Heat and light. Possibly sound as well.
What is the difference of endothermic reaction from exothermic reaction?
Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature, while exothermic reactions release heat to their surroundings, causing an increase in temperature. In endothermic reactions, the products have more energy than the reactants, whereas in exothermic reactions, the products have less energy than the reactants.
How does chemical energy form?
Chemical energy forms when atoms or molecules undergo chemical reactions, which may involve the breaking and forming of chemical bonds. During these reactions, energy is either released (exothermic) or absorbed (endothermic) in the form of heat or light. The energy stored in the bonds of the reactants is transformed into chemical energy in the products.
What can be exothermic?
Any action - chemical, physical, electrical or atomic - that gives off heat energy is exothermic. A few examples are a light bulb, a campfire, your computer CPU (when in use) and rubbing two sticks together. "Exo" and "thermic" are both combined forms from early Greek, the one meaning "out" or "outward", the other meaning "heat". The opposite is "endothermic", "endo" meaning "in" or "inward".
Is energy created during an exothermicreaction?
Mass and energy can never be created or destroyed, but can change forms. An exothermic reaction releases stored chemical energy and transforms it into heat, but the total amount of energy does not change.
Is barium hydroxide endothermic or exothermic?
it is exothermic since it produces energy. if endothermic it would use up energy.
Which type of energy is released in chemical reactions kinetic solar or potential?
The type of energy released in chemical reactions is potential energy. This potential energy is stored in the chemical bonds of molecules and is transformed into other forms of energy such as heat, light, or kinetic energy during a reaction.
Why is the reaction between water and acid exothermic?
The reaction between water and acid is exothermic because it releases heat energy as it forms new chemical bonds in the products. The formation of these bonds is more stable and has lower energy than the reactants, resulting in a net release of energy in the form of heat.
What is the overall energy change that occurs when a solution forms?
The overall energy change that occurs when a solution forms is the sum of the energy required to break the solute-solute and solvent-solvent interactions (endothermic process), and the energy released when solute-solvent interactions are formed (exothermic process). This results in either an endothermic or exothermic process, depending on the relative magnitudes of these interactions.
Energy stored in fuel what do you call it?
The energy stored in fuel is called chemical energy. This energy is released through chemical reactions, such as combustion, to produce heat and other forms of energy.
Which compound forms exothermically?
An exothermic reaction releases heat energy to the surroundings. Compounds like combustion reactions (e.g. burning of wood or gasoline) typically release heat during their reaction, making them exothermic.
What similarities do nuclear energy and chemical energy share?
Both nuclear energy and chemical energy involve the release of stored energy from a substance. However, nuclear energy is released from the nucleus of an atom through nuclear reactions, while chemical energy is released from the rearrangement of atoms in chemical reactions. Both forms of energy can be harnessed for various applications.
