∙ 12y ago
A decomposition reaction breaks down a compound into its elements. For example, when an electric current is passed through water, it decomposes into hydrogen gas and oxygen gas.
2H2O --electrolysis--> 2H2 + O2

What are the uses of chemical formulas?
The uses of chemical formulas are mainly to show how the various elements are in any compound. This will indicate how a particular chemical reaction takes place.
What is the chemical reaction that uses heat to decompose an compound?
Heat can be used to break compounds because there is a chemical reaction that takes place and it causes the particles in the compound to break
Do inert elements gain electrons?
There is no electron exchange when no reaction takes place (this is what 'inert' means)
What is a metal compound formed when a reaction takes place with an acid?
A salt or a hydroxide are obtained.
Why air contains N2 and O2 instead of NO?
Elements prefer to live in their natural forms.N2 and O2 are more stable than NO.Added:Air is a mixture of N2 and O2 molecules, where NO is a compound, chemically formed by reaction: N2 + O2 --> 2 NO. This reaction does not take place at normal conditions as in the air around us.

What is a substance made up of two or more elements called?
Compound A compound or a mixture depending upon whether they are combined chemically [have chemically reacted: Carbon and Oxygen: carbon Dioxide] or are simply two or more elements in a physical mixture without any chemical reaction having taken place [Air a mixture of Nitrogen, Oxygen and other minor constituent gases]
What must be done to obtain an element from its compound ore?
to obtain an element from its compound it is necessary to cause a chemical reaction to take place
Why is breaking down a compound into its elements consid A chemical change?
its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically
Why is iron changing to rust a chemical change?
As changing Iron to Rust is changing the actual chemical elements of the compound. It becomes Iron Oxide, or Iron with an Oxygen reaction having taken place so that the material is different.
