It must be exactly 10.0 grams..... law of conservation of mass

Answer:

The answer is B

Explanation:

The answer is exactly 10 grams because of the law of conservation of mass which states that for a closed system, the mass of the system must remain constant over time, hence the mass of the products formed after the reaction cannot increase nor decrease as this will violate the law stated earlier.

The above explanation proves the reason for option B. The remaining options suggest either an increase or a decrease in the mass of the product formed which is not possible.

Answer: It showed that all atoms contain electrons.

Explanation:

  • J.J. Thomson's experiments inside a cathode ray tube in the presence of an electric field showed that all atoms contain tiny negatively charged subatomic particles "electrons".
  • Also, Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."
  • Furthermore, Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny positively-charged nucleus.
  • Then, Rutherford proposed the nuclear model of the atom based on these results.
