Answer:
This chemical equation is balanced
Mass is conserved
Explanation:
Properly writing the equation:
2H₂ + O₂ → 2H₂O
In this chemical equation, we have that the equation is well balanced and mass is conserved.
A balanced chemical equation is one in which the number of atoms of each elements on the reactant and product sides are the same. In the equation above:
Reactant side Product side
H: 4 atoms 4 atoms
O: 2 atoms 2 atoms
The coefficients offer a way of balancing chemical equations properly.
The law of conservation of mass states that "mass is neither created nor destroyed in an isolated systems where chemical reactions occur". All chemical equations must be written to show the law of conservation of mass. From the equation above, the mass is the quantity of substance that is present in a system, by the balanced chemical equation mass is conserved.
