A chemical equation is shown. 4FeS + 7O₂ → 2Fe₂O₃ + 4SO₂ Which statement is correct about the chemical equation?

It is unbalanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products.

It is balanced because the mass of the reactants is equal to the mass of the products.

It is unbalanced because the mass of the reactants is greater than the mass of the products.

It is balanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products.

Look at the following chemical equation. 2H₂O₂ → 2H₂O + O₂ Does this equation follow the conservation of mass?

Yes, because each atom that is in the reactants is found in the products.

Yes, because the mass of the reactants is greater than the mass of the products.

No, because the mass of the reactants is greater than the mass of the products.

No, because the coefficient of the reactant is less than the coefficient sum of the products.

Look at the following chemical equation. H₃PO₄ + 5HCl → PCl₅ + H₂O What is true about this chemical equation?

It is balanced because the mass of the reactants is equal to the mass of the products.

It is balanced because the number of reactants is equal to the number of products.

It is unbalanced because the mass of the reactants is greater than the mass of the products.

It is unbalanced because the mass of the reactants is less than the mass of the products.

Which chemical equation follows the law of conservation of matter?

C₅H₁₂ + 7O₂ → 5CO₂ + 6H₂O
