Iron when combined with oxygen form rust
WebWhen iron rusts, water and oxygen in the air react with the iron to form iron oxide. In this experiment, students set up iron wool to rust in a test tube full of air, inverted in a beaker of water. As the iron wool reacts, rusts and removes the oxygen from the air, water is … 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. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3 #CARRYONLEARNING Advertisement Previous Advertisement

A. depends on the reaction conditions. B. is less than the mass of the reactants. C. is the same as the mass of the reactants. D. is greater than the mass of the reactants.
WebIron combusts in oxygen to form various iron oxides, mainly iron (III) oxide: 4 Fe (s) + 3 O2 (g) ==> 2 Fe2O3 (s) Iron in its usual bulk solid form will only burn when in pure oxygen with when a great deal of heat is supplied. This is what a cutting torch does. 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).
WebOct 22, 2024 · Answer: TRUE Explanation: Rust forms on the surface of an iron or steel object, when that surface comes into contact with oxygen. The oxygen molecules collide with the iron atoms on the surface of the object, and they react to form iron oxide. Advertisement Answer 3 people found it helpful ivan31008 Answer: False Explanation:
WebAug 9, 2015 · Rust forms when oxygen reacts with iron, but simply putting iron and oxygen together isn't sufficient. Although about 21% of air consists of oxygen, rusting doesn't occur in dry air.
