Chemistry Chemical Reactions


- Info:

- Chemical reaction is simply a rearrangement of the way that atoms are connected together to form molecules.

- Following chemical formula shows how combination of hydrogen gas with oxygen gas forms water.


H2+1/2O2 H2O


- Initially, hydrogen atoms are connected together in pairs to form H2 molecules of hydrogen gas.

- Initially, oxygen atoms are also connected together in pairs to form O2 molecules of oxygen gas.

- Water is created when one H2 molecule binds with single oxygen atom and forms water molecule.

- Other half of the O2 usually combines with another H2 to form a second water molecule.
