Final answer:
The chemical reaction 2H₂O₂ → 2H₂O + O₂ depicts the decomposition of hydrogen peroxide into water and oxygen, symbolizing a balanced chemical reaction that follows the law of conservation of matter. The correct answer is O two hydrogen peroxide molecules yields two water molecules plus an oxygen molecule.
Step-by-step explanation:
The chemical reaction 2H₂O₂ → 2H₂O + O₂ represents the decomposition of hydrogen peroxide into water and oxygen. This reaction demonstrates a balanced chemical equation, which means the number of atoms for each element is the same on both sides of the equation, adhering to the law of conservation of matter.
Hydrogen peroxide (H₂O₂) is a compound composed of two hydrogen atoms bonded to two oxygen atoms.
When it breaks down, it forms water (H₂O), which has one oxygen atom bound to two hydrogen atoms, and gaseous oxygen (O₂), which consists of two bonded oxygen atoms and is categorized as a homonuclear molecule since it is not a compound but a molecule of the same type of element.
The reactant hydrogen peroxide is broken down into water, containing one oxygen atom bound to two hydrogen atoms (H2O), and oxygen, which consists of two bonded oxygen atoms (O2). In the equation below, the reaction includes two hydrogen peroxide molecules and two water molecules.
