Hydrogen peroxide, often used in solutions to cleanse cuts and scrapes, breaks down to yield water and oxygen: Hydrogen peroxide, H₂O₂(aq) → Hydrogen, H₂(g) + Oxygen, O₂(g)

b. Which of the substances are chemical compounds, and which are elements?

Accepted Answer

Hello, everyone. Today, we're being given the following problem. Rust is formed by the reaction of iron and oxygen gas in the presence of water. And so we have the following reaction, identify the elements and compounds in the reaction. So first let's define what these terms mean. So an element can be defined as a something that is composed of just one type of atom. So it's only one type of atom. And then we have a compound and a compound is going to be two or more elements and they're typically gonna be bonded together. So if we look at our compound, if we look at our materials here, we have iron, it's only one sort or one type of atom. So we're gonna call iron an element. After iron, we have our oxygen gas. Once again, this is going to be an element. Since it is only composed of one type of atom, we have water here in the liquid form and it is composed of hydrogens and oxygens. So we can say that water is a compound and then we have rust that is going to be composed of this structure here. And of course, this is going to be a compound since there are more than one types of atoms in that. And the answer choice that best aligns with these definitions is going to be a, that iron is an element. Oxygen is a compound and the other compounds or the elements are going to be iron and oxygen and the compounds are going to be water and rust. And with that, we've answered this question overall, I hope it's helped. And until next time.
