The hypothesis of Thomson's atomic model was that an atom is posively charged sphere and in which negatively charged electron are embedded in it but later it was found to be not true by niels Bohr.
The above hypothesis of Thomson's atomic model was false because according to niels Bohr 'The mass of any atoms is localize at the center of an atom which is positively charged while negatively charged electrons revolved around the positive charged'.
The J.J Thomson give the world Thomson model of the atom in 1904 . Thomson model is also known as the plum pudding model .

Answer:
The total number of molecules remains the same
Answer:
The total mass of the reactants is <u>equal to </u> the total mass of the products in a chemical reaction.
Explanation:
Answer: A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!! :D
