Which shows the correct order of steps in the formation of coal? layers of dead plants pile up → plant matter is buried by rocks and dirt → dead plants fall in swamp → plant matter is compressed and is exposed to heat → coal forms plant matter is compressed and is exposed to heat → dead plants fall in swamp → layers of dead plants pile up → plant matter is buried by rocks and dirt → coal forms plant matter is buried by rocks and dirt → dead plants fall in swamp → layers of dead plants pile up → plant matter is compressed and is exposed to heat → coal forms dead plants fall in swamp → layers of dead plants pile up → plant matter is buried by rocks and dirt → plant matter is compressed and is exposed to heat → coal forms

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
