Answer:
Iron(III) Oxide
Explanation:
You can tell that this formula is for the molecule Iron(III) oxide because it has two iron atoms and three oxygen atoms.
Fun Fact: There are three main types of iron oxides, with this being one of them.
Hope this helped! :^)

An element’s atomic number is equal to the number of protons in that element’s nucleus. The mass number is the total number of an atom’s protons and neutrons. Protons have a positive charge; electrons have a negative charge; and neutrons are electrically neutral.
Putting it all together, given that the atomic number of lead is 82, the number of protons a lead atom contains is 82. The number of neutrons would be the difference between 207 and 82, or 125 neutrons. Finally, since you have a neutral atom, there must be an equal number of electrons as the number of protons—that is, 82 electrons.
Thus, you’ve got 82 protons, 125 neutrons, and 82 electrons.
Why is hydrogen a “cleaner” fuel source than gasoline?
hydrogen is natural created and in the air already, gas is a fossil fuel and is killing the Ozone layer. carbon dioxide is a poison and can really harm us and the world.
this paragraph basically explains the question
Compared to the carbon dioxide that is produced when we burn gasoline, ethanol, and other carbon-containing fuels, the water produced by burning hydrogen has a less harmful effect on Earth’s climate. If we can power our cars with hydrogen without producing carbon dioxide, then why don’t more vehicles use hydrogen fuel? Unfortunately, the technology needed to use hydrogen as a fuel is expensive, and storing hydrogen fuel can be difficult. Also, the most common way of getting pure hydrogen is by separating it from substances that contain carbon—so although burning hydrogen fuel does less harm to Earth’s climate than burning carbon-containing fuels, the production of hydrogen fuel is still a problem for scientists trying to reduce climate change.
