How does iron react with steam when heated?
Fe is the chemical symbol for iron. When iron reacts with steam it corrodes, or rusts.
Does iron rust faster in salt or fresh water?
Rust is essentially oxidation, or a chemical interaction involving oxygen. When oxidation occurs in some elements, a thin film is formed as a result--such as the green layer that copper acquires. Other elements, such as iron, show rust as evidence of oxidation. If iron--or metal related to iron--is exposed to an environment both oxygen-rich and friendly toward the catalyst, then the oxidation process will begin. Molecules of iron at the surface of the iron object will exchange atoms with the oxygen in the air, and what atoms are left will form a new substance, the reddish-brown rust.Oxidation is an electrochemical process that acts somewhat like a battery, exchanging small amounts of electricity. Like batteries, a solution helps this process by allowing electrons to move more easily between the two elements, and also like batteries, different solutions work better than others. Water takes some of the atoms and changes them into a light form of acid as the oxidation process continues, which helps metal rust even faster.This acidic transformation occurs with pure water, but when the water is already salty it starts out as a minor acid and becomes an even more powerful electrolyte, facilitating the rusting process. There is then a hierarchy in the rust process. Rust does not easily form in dry climate, but in a wet climate the oxygen can access the metal more easily through the water vapor, and rust occurs much faster. Pure water forms an acidic solution and allows the oxidation process to happen more easily, and salty water works even better since it is already a catalyst. Prime rust conditions occur when the metal is regularly exposed to salt water and air.
What is the method of separating iron filling and powdered sugar mixtures?
It can easily be separated by the process of magnetic separation.
Is iron sulphide reversible or irreversible?
Iron sulfide is a chemical compound. A process or reaction may be reversible or irreversible; a compound isn't.
What happens to iron placed in a test tube with a stopper?
Iron and oxygen in a test tube alone will not react (observed by placing a piece of iron in a test tube with a stopper).Iron and water in a test tube alone will not react (observed by completely submerging a piece of iron in water in a test tube with a stopper).Iron, water and oxygen in a test tube will react (observed by placing a piece of iron in a test tube and submerging half of it with water). The following reaction will take place: iron + water + oxygen ----> hydrated iron(III) oxide. Hydrated iron(III) oxide is the chemical name for rust, which will appear as orange flaking on the piece of iron. To speed up this reaction you can use a bit of salt as a catalyst.
What is used in the haber process?
its an iron catalyst (iron oxide)
Which process is iron used as catalyst?
The Haber process (making amonia using nitrogen and hydrogen).
What is the catalyst used in haber?
its an iron catalyst (iron oxide)
What is the purpose of the iron in the reactor in the haber process?
The purpose of the iron in the reactor in the haber process is to speed up the reaction.
What role does iron oxide play in the Haber process?
the role it plays is by using an iron oxide catalyst eliminates the need for excessively high temperatures and without the catalyst the production of significant amounts of ammonia is too slow to be economical
Identify the metal used as the catalyst in the Haber process?
its Fe- iron. It is used as a catalyst to speed up the exothermic reaction between N2 and H2 to make NH3.
Why it is necessary to remove co when ammonia is obtained by habers process?
It is important to remove CO in the synthesis of ammonia as CO adversely affects the activity of the iron catalyst, used in Haber's process.
Why is it necessary to remove CO when ammonia is obtained by Habers process?
It is important to remove CO in the synthesis of ammonia as CO adversely affects the activity of the iron catalyst, used in Haber's process.
What are the raw materials used in the haber process?
The Haber process is good for producing ammonia. Per Wikipedia, use the following: Pressure 150-250 bars, temperature 300-550°C Have the reactant gases (1 part nitrogen to 3 parts hydrogen by volume) flow through 4 successive beds of magnetite (iron oxide) catalyst, cooling after each catalyst bed. The Haber process customarily starts with methane as the source of hydrogen gas, adding some steps.
What is the product of the Haber process used for?
The Haber process (also called the Haber-Bosch process) is the nitrogen fixation reaction of nitrogen gas and hydrogen gas over an enriched iron or ruthenium catalyst, which is used to produce ammonia. It's main use is in fertilizers, color compounds and N-polymers like nylon.N2 + 3H2 --> 2NH3(exothermic)
Describe what the habor procces does?
The Haber process is the reaction between nitrogen and hydrogen to produce ammonia. An Iron Catalyst is used. The reaction is reversible, so is quite complicated to maintain.
Process of converting nitrogen gas into ammonia?
Is known as nitrogen fixation, done with the enzyme nitrogenase found in nitrogen fixing bacteria.
