no
The chemical energy in the reactants is almost equal to the chemical energy in the products
During a chemical reaction matter is neither created nor destroyed
Mass can neither be created nor destroyed in a chemical reaction
The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.
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

no
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.
The chemical energy in the reactants is almost equal to the chemical energy in the products
The chemical energy in the reactions is almost equal to the chemical energy in the products
In any chemical reaction atoms are neither created nor destroyed.
During a chemical reaction matter is neither created nor destroyed
The law of Conservation of mass states that 'mass is neither created nor destroyed in a chemical reaction'.
No. Atoms, which are matter, are neither created nor destroyed in a chemical reaction, but they are rearranged.
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.
