Can u tell me what are the evidences of a chemical reaction?
Some signs of a chemical reaction include color change, formation of a gas or bubbles, production of heat or light, and formation of a precipitate (solid) in a liquid.
We can determine if a chemical reaction has taken place by conducting experiments and observing for any of the signs mentioned above. We can also test for changes in the chemical composition of the substances before and after the reaction.
Yes, some chemical reactions can be reversed through a process called a reversible reaction. This occurs when the products of the reaction can be converted back into the original reactants.
Catalysts are substances that can speed up a chemical reaction without being consumed in the process. They lower the activation energy required for the reaction to occur, making it happen faster.
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, but can only be rearranged. This means that the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
