Why O2 is necessary for rusting?
O2 is necessary for the rusting because the iron forms an iron oxide complex with the oxygen. Fe (s) + O2 (g) --> Fe2O3 (s)
Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
What part of a rock will undergo rusting?
Rusting is a term adequate only for iron and iron alloys.
Is there any difference between rusting and combustion since both involve oxidation?
Differences:RUSTING :Rusting is a slow process.Little heat is released.Both air and moisture are necessary for rusting.COMBUSTION:Burning is fast oxidation.large amounts of heat are released.Only air is necessary for combustion.In other words, Rusting is much slower than combustion, and rusting in the strictest sense can occur only with iron or its alloys.
Does air rust iron?
Rusting is a chemical reaction - an oxydation; the essential factor for iron rusting is oxygen.
Why O2 is necessary for rusting?
O2 is necessary for the rusting because the iron forms an iron oxide complex with the oxygen. Fe (s) + O2 (g) --> Fe2O3 (s)
Why is it necessary to paint iron gates?
To stop them rusting.
Which one is a chemical change rusting of iron or melting of iron?
rusting of iron
How is bending different from iron rusting?
iron bending different from iron rusting
What conditions will make iron and steel rust?
Rusting occur in iron when it reacts with oxygen and water...the less salts in the water the faster the rusting occurs...and the more percentage of oxygen the faster it rusts.
Does rusting of iron is a reaction of iron and nitrogen?
Oxidation (rusting) of iron metal is the reaction of iron and oxygen
Is iron rusting in a charge of chemical?
No, iron rusting is oxidation process
What is the materials causing iron rusting?
Its the moisture which causes rusting of iron
How is iron gate prevented from rusting?
How is iron gate is prevented from rusting
Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
Which one is a chemical change -rusting of iron or melting of iron?
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
What reactions occurs quickly a rusting of iron or b explosion?
rusting of iron
