How does iron react with air and water?
Iron reacts with oxygen in air to form iron oxide, commonly known as rust. When iron reacts with water, it undergoes corrosion which is accelerated in the presence of oxygen. The reaction with water and oxygen produces hydrated iron oxide, also known as rust.
What is the salt given off by this reaction Fe plus H2SO4 -- FeSO4 plus H2?
The salt given off by this reaction is iron(II) sulfate, FeSO4. This compound is formed when iron reacts with sulfuric acid to produce iron sulfate and hydrogen gas.
When iron reacts with oxygen to form rust each iron atom?
When iron reactions with oxygen to form rust, the iron atoms, Fe reacts with the oxygen atoms, O2 to create iron (III) oxide, Fe2O3.4Fe + 3O2 -----> 2Fe2O3Or2Fe + 3/2O2 -----> Fe2O3
What gas is given off when magnesium reacts with sulfuric acid?
Hydrogen gas is given off when magnesium reacts with sulfuric acid.
Oxygen can cause rocks containing iron to rust in the process of what?
Photosynthesis. Oxygen molecules are released as a by product of photosynthesis, which causes iron to rust. The rust on rocks also proves we had an abundance of oxygen 2.5 billion years ago, which was caused by cyanobacteria ( and others as well maybe ).
Does rusting use or produce heat?
The rusting of the iron is a slow oxidation. In this slow oxidation matter links up with oxygen very slowly. There is no flame. THE HEAT THAT IS GIVEN OFF IS SO SLIGHT THAT IT CANNOT BE FELT.
What gas is given off when Cu reacts with HCL?
Hydrogen gas is given off when copper reacts with hydrochloric acid (HCl) according to the reaction: Cu + 2HCl -> CuCl2 + H2.
Where does the oxygen come from that is reacting with a piece of burning iron?
When oxygen is reacting with iron it generally comes from the air, but it can also come from oxygen disolved into water. There are other ways it can occur but I do not know these. But unless it is in a vacuum, the oxygen comes from the surrounding environment like air or water.
What gas is given off when a metal reacts with acid?
Acid gives off hydrogen gas if it is hydrogen containing acid.
What gas is given off when ethanoic acid reacts with magnesium?
Hydrogen gas is given off when ethanoic acid (acetic acid) reacts with magnesium. This is a result of the displacement reaction between the acid and the metal.
When carbon reacts with an acid what gas is given off?
carbon dioxide. CO32- + 2H+ -> CO2 + H2O
When magnesium reacts with hydrochloric acid what acid is given off?
No acid is formed. The reaction produces hydrogen gas and magnesium chloride, a salt.
