NaCl (Sodium chloride)
LiF (Lithium fluoride)
It can be more effective in liquids.
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.
1. Rust, or Fe2O3, is a Chemical Compound.
2. Carbon is a Chemical Element found as C on the periodic table.
3. Apple Juice is a Heterogeneous Mixture, as it is uniform throughout. If it wasn't uniform, there would be yucky lumps in your apple juice :)
If I helped you out, I would greatly appreciate if you went through my other answers I gave you and gave them the brainliest answer :)
