Final answer:
The correct statement supporting the law of conservation of mass is (D) mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas, illustrating that the mass of reactants equals the mass of the products.
Step-by-step explanation:
The question you've asked relates to which statement supports the law of conservation of mass in the reaction between two liquids that produce a solid and a gas. According to the law of conservation of mass, the total mass of the reactants (Liquid 1 and Liquid 2) before the reaction must equal the total mass of the products (solid and gas) after the reaction. Therefore, the correct statement is (D) mass of Liquid 1 + mass of Liquid 2 = mass of solid + mass of gas.
An example of the law of conservation of mass is when you combine vinegar (acetic acid) with baking soda (sodium bicarbonate). The reactants will produce carbon dioxide gas and aqueous sodium acetate. If you weigh the reactants before the reaction and the products after the reaction, you'll find that the total mass remains the same, demonstrating the conservation of mass.
To prove that the law of conservation of mass is obeyed during a chemical reaction, you would balance the chemical equation to ensure that the number of atoms of each element is the same on both sides of the equation, which implies that mass is conserved as atoms are not lost or gained.
