Answer:
B.) sodium water right arrow. sodium hydroxide hydrogen
Explanation:
Reactants are listed before the arrow and products are listed after the arrow. This symbolizes the reactants turning into the products.
Reactants --> Products
Reactants are the molecules which react with each other to make new molecules. Since sodium and water are being combined, they are the starting molecules. Products are the molecules made after a reaction occurs. Sodium hydroxide and hydrogen gas are produced, making them the ending molecules. The balanced chemical equation is:
2 Na⁺ (s) + 2 H₂O (l) --> 2 NaOH (s) + H₂ (g)
