WebSo we have iron and oxygen forming iron oxide, which is also called rest. Our task here is to name the reactant on the products. So anything on the right side of, um, an arrow or something that looks like ingredients. Those are my reactive. Those are my before That's what I often call it with my students. But before things than anything after the reaction … WebWhen iron and oxygen combine to make iron oxide (rust), heat is given off, which means the reaction is exothermic (exo means "out" and therm means "heat," so heat is sent out when the reaction occurs). WebAnswer: true Explanation: One of the most common iron oxides is iron (III) oxide, known as rust. The chemical formula for rust is Fe2O3. Rust is formed when iron reacts with oxygen in moist air.
