Yes because I went through college and learned this
These are related but can be independent, because it is possible to, the theories are studied in mathematical logic, especially in model theory
I think the answer is b because that is true
White light is what the eye sees when wavelengths of all colours reach the eye.
It is a combination of Red, Blue and Green wavelengths of light, that is perceived as white.
D should be the correct answer. isotopes are atoms that have the same atomic number (number of protons) but different atomic masses (number of protons and neutrons). isotopes also have the same number of electrons since atoms need to have equal numbers of protons and electrons to not be considered ions. Since the number of protons determines the chemical properties of the atom, we can say that all isotopes have the same chemical properties due to the fact that all isotopes have the same atomic number.
I hope this helps. Let me know in the comments if anything is unclear.
