Answer:
a heterogeneous mixture
Explanation:
an example would be sand and water because it can be filtered which is a physical mean of separation.
The answer is indeed carbon dating, but let me explain it to you a little bit better: This is so because Carbon dating is the method that has the determination of the age of an organic matter. That is why we can say that that uses a mathematical equation and the half-life of decay to determine the exact date of a fossil. Hope this clarifies everything
Answer:
If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.
Explanation:
An atom is the smallest amount of matter that undergoes chemical changes and is made up mainly of subatomic particles: electrons, protons and neutrons. The atomic nucleus is made up of protons, with a positive electric charge, and neutrons, which have no charge, while electrons, with a negative electric charge, revolve around the nucleus.
A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. In other words, although it has an electric charge, it is balanced between protons, electrons and neutrons. So in a neutral atom, the number of electrons equals the number of protons because the negative charge of the electrons is offset by the positive charge of the protons.
