Question

sodium bicarbonate (nahco₃) is commonly known as baking soda. sodium bicarbonate is a white solid that can dissolve in water. under the proper conditions, sodium bicarbonate can release carbon dioxide (co₂) gas. which of the following is not a physical property of sodium bicarbonate?
it is white.
it is a solid.
it can dissolve in water.
it releases carbon dioxide.

Explanation:

Physical properties describe a substance's appearance or behavior without changing its chemical composition. Color (white), state (solid), and solubility (dissolve in water) are physical properties. Releasing carbon dioxide involves a chemical change (a chemical reaction occurs), so it is a chemical property, not a physical one.

Answer:

It releases carbon dioxide.
