Is this a balanced equation?​

Answer:

The equation is not balanced.

Explanation:

The Law of Conservation of Matter is also called the law of conservation of mass or the Lomonosov-Lavoisier Law. This law postulates that "the mass is neither created nor destroyed, it only transforms." This means that the reactants interact with each other and form new products with different physical and chemical properties than the reactants because the atoms of the substances are arranged differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the amounts of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends. . In other words, then the mass before the chemical reaction equals the mass after the reaction. The exception to the rule is nuclear reactions, in which it is possible to convert mass into energy and vice versa.

This is, te law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.  

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:

Left side: 2 hydrogen H and 2 oxygen O  

Right side: 2 hydrogen H and 3 oxygen O

Since the quantity of each element is different on each side of the reaction, the equation is not balanced.

The balanced equation is:

2 H₂O₂ → 2 H₂O + O₂
