Things that could speed up a chemical reaction include, temperature, nature of the reactants, catalysts, surface area, and concentration. Which of these may apply to your experiment will almost always vary depending on the type of experiment.
Temperature
Bubbles, and heat change are examples of chemical reactions. When a chemical reaction happens, a compound is formed. It cant be separated. Another example could be change of colour. -making caramel sauce -getting a suntan
Oxygen as most reactions have it although it could also be hydrogen
The chemical reaction is:Fe + CuSO4 = FeSO4 + CuIt is a single displacement reaction.
How could a chemist find out how much mass is given off as gas during a chemical reaction

The proper term for the phenomenon of reaction rates is known as chemical kinetics. Generally for any chemical reaction factors such as temperature, concentration, pressure, physical state, presence of a catalyst, and the reaction rate order. Reaction rate order is specific for each chemical reaction. So to sum it all up, if you influence the environment in a manner that does not change one of these listed variables, then it will not likely do anything to a reaction rate. But to be honest, I can't think of a single thing you could do to a reaction that wouldn't influence one or more of these parameters.
the chemical shall be changed

How could a chemist find out how much mass is given off as gas during a chemical reaction
There could be many such as concentration of reactants, temperature, pressure, volume, presence of catalysts etc., depending on the state of matter of the reactants and products.
could cause chemical reaction
battery
nuclear decay rates take more time and chemical reaction rates could happen fast.
bublly bubbles. could u please add more info
