Answer:
B) irreversible process
Explanation:
The process given here is irreversible.
Your answer is B and the element is Carbon
So what your looking for is matching isotopes. Isotopes are elements that are the same in amount of protons but different in mass meaning different number in neutrons. Because when you add the total protons and neutrons together you get your atomic mass. So this can be written as X=said element, top number above=different atomic mass, bottom number below=atomic number. Hope this help!!
Be careful because answer A has same masses but different atomic numbers so different atoms(elements)!!!
Answer:
D) How many valence electrons the atom contains.
This is the only closest one
because the number of electrons in the outermost shell is the correct answer
