This is how I memorized the ionic formulae. It is a lot to remember, so it does take some time and studying. But this website helped me learn it fast and in a suuuper unique way. I learned it 3 years ago and could still name quite a bit of them. Hope this helps!!!
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment.
Answer:
1249.88 mol.
Explanation:
∵ no. of moles of Fe = mass of Fe/atomic weight of Fe.
<em>∴ no. of moles of Fe </em>= (6.98 x 10⁴ g)/(55.845 g/mol) = <em>1249.88 mol.</em>
Neutrons actually don't carry an electrical charge, which is why they are called neutrons because they are "Neutral".
