Question

what law is shown by the balanced equation? 2h₂ + 1o₂ → 2h₂o newtons first law conservation of energy bohrs atomic theory conservation of mass

Explanation:

A balanced chemical equation like 2H₂ + O₂ → 2H₂O demonstrates that the number of atoms of each element is the same on both sides of the equation. This shows the conservation of mass as mass is neither created nor destroyed in a chemical reaction. Newton's First Law is about motion, conservation of energy is about energy - not atoms in a chemical equation, and Bohr's Atomic Theory is about the structure of atoms.

Answer:

Conservation of Mass
