The chemical energy in the reactants is almost equal to the chemical energy in the products
In an ordinary chemical reaction, energy is conserved, meaning the total energy before and after the reaction remains constant. This energy can be released or absorbed in the form of heat, light, or other forms, depending on whether the reaction is exothermic (releases energy) or endothermic (absorbs energy). Additionally, the energy changes often involve breaking and forming chemical bonds, which requires or releases energy. Overall, the law of conservation of energy dictates that energy is neither created nor destroyed, only transformed.
It is neither, the reaction is the process. The chemicals 'put in' to the reaction are called reactants, and those formed by the reaction are products
The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.
In a chemical reaction, the total mass of the reactants should be equal to the total mass of the products formed (law of conservation of mass). This means that mass is neither created nor destroyed during a chemical reaction.

The chemical energy in the reactants is almost equal to the chemical energy in the products
Energy is either released or absorbed in form of heat or light. Energy participates in all reactions.
Energy released by a chemical reaction is released as heat to the surroundings thus rising the temperature of the room or lab etc where the reaction is taking place. Similarly, energy absorbed by endothermic is either supplied by external heating of reaction mixture over a flame or absorbed from surroundings.
A rotting apple is an example of a reaction in which energy is neither absorbed nor released because the process is exothermic (energy is released) but the heat is absorbed by the surroundings, so the system doesn't gain or release energy overall. The energy just moves from the apple to the environment.
When 2 atoms combine to form a molecule, energy can be either absorbed or released, depending on the specific atoms involved and the type of bond being formed. This process can result in either an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed).
Rotting of an apple is a biochemical process. The energy needed for the decomposition is already present in the apple in the form of chemical bonds. As these bonds break down during rotting, the energy is used up without being released or absorbed from the surroundings, making it a non-energetic process.
No. Atoms, which are matter, are neither created nor destroyed in a chemical reaction, but they are rearranged.
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants before a reaction must equal the total mass of the products after the reaction.
In any chemical reaction atoms are neither created nor destroyed.
The simple ANSWER IS yes!!! The reaction that does this is referred to as 'Exothermic'. Energy can be absorbed during a chemical reacton, but it needs an activation energy to start the reaction. For all chemical reactions there is always a change of energy. No reaction is ever 'energy less'. However, the exchange of energy can be very small. Example of an exothermic reaction is sulphuric acid and sodium hydroxide. if you hold the beaker the two reactants are in , it will feel warm. This is an exothertmic reaction. For the thermal decomposition of calcium carbonate, you have to heat it up; you are driving energy in, so it is an endothermic reaction. Other endo thermic reactions, may feel cold, they are absorbing heat at ambient room temperature.
