There must be a light reaction first before dark reaction. This is so that there is something to be compared.
Two substance were made to react in a closed vesselwhich will remain the same before and after the reaction?
If the reactants and products in a chemical reaction exist in the same physical state (solid, liquid, gas) and the total number of atoms of each element remains constant before and after the reaction, the mass of the substances in a closed vessel will be the same. This is known as the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction.
What are two physical properties and two chemical properties of a bag of microwave popcorn before popping and after?
Two physical properties of a bag of microwave popcorn before popping are its mass and volume, which remain constant before and after popping. Two chemical properties that change after popping are the composition of the kernels, which undergo a chemical reaction to turn into fluffy popcorn, and the release of aroma compounds due to the Maillard reaction during popping.

What happens when a physical reaction occurs?
During a physical reaction, the arrangement of atoms and molecules changes, but no new substances are formed. This means that the chemical composition remains the same before and after the reaction. Examples of physical reactions include changes in state (solid to liquid, liquid to gas) or changes in shape.
