Atoms and chemical reactions
Law of conservation of mass
During a chemical transformation atoms in reactants combine to each other in a different way to form some products but any atom appears or disappears therefore the total mass is the same.
Law of conservation of mass:
For a chemical transformation, total mass of reactants consumed is the same as total mass of products formed.
Example:
Combustion of carbon
Carbone+ dioxygen → carbone dioxide
If 12 g of carbon reacts with 26 g of oxygen then it is formed:
12 + 26 = 28 g carbon dioxide
