It is a chemical change (reaction) because the chemical composition of the products (O2 and H2) is different from the chemical composition of the water (H2O).
H2 +o2 --->h2o
H2 +o2 --->h2o
This is a chemical change. Chemical reactions are chemical changes.
The chemical equation is:2 H2 + O2 = 2 H2O
Chemical equations show what happens when a chemical change occurs. For example, in the combustion of Hydrogen(H2), water(H2O) is formed. The chemical equation for this reaction is: 2H2 + O2 -----> 2H2O This chemical equation shows that when H2 reacts with O2 , H2O is formed.
Yes, compounds can be broken down into their component elements through various chemical reactions. For example, water (H2O) can be separated into hydrogen (H2) and oxygen (O2) through the process of electrolysis.
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
The che chemical equation is:2 H2 + O2 = 2 H2O
H is the atomic symbol for hydrogen, the 2 subscript means it is diatomic.
The correct chemical equation for forming water molecules is: 2H2 + O2 -> 2H2O. This equation shows the combination of two molecules of hydrogen gas (H2) with one molecule of oxygen gas (O2) to produce two molecules of water (H2O).
Chemical Name = Oxygen Chemical Symbol = O There is no chemical formula for elements.
The chemical formula for hydrogen fuel is H2, which means it consists of two hydrogen atoms.
