Answer:

NaOH + H2SO4 → Na2SO4 + H2O

explaination:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element must be the same on both sides of the equation. In option B, the equation is balanced: there is 1 sodium (Na), 2 hydrogens (H), 1 sulfur (S), and 4 oxygens (O) on both sides. In contrast, the other options do not have balanced atoms, indicating that they do not follow the law of conservation of mass.
