I think it’s B having second thoughts
Approximately twenty-five elements occur naturally on earth. Remaining elements either have to be synthesized or obtained through chemical reactions.
Answer:
Not very successful considering the fact that there is still acid rain even with more advances in technology such as the development of hydroelectric power plants and other renewable forms of energy so as to reduce the continuous burning of fossil fuels.
Explanation:
Acid rain is produced when sulfur and nitrogen in their oxide forms are released into the atmosphere where they get to meet with water and other chemicals. Since water contains hydrogen and oxygen, it reacts with sulfur and nitrogen in their oxide form to produce weak acids which come down to the earth as it rains. Fossil fuel combustion is a man-made practice of releasing sulfur and nitrogen in their oxide form into the atmosphere which eventually results in acid rain.
Answer: N-14
Explanation: When C-14 undergoes radioactive decay, atoms of N-14 are formed
