Quizplus · Accepted Answer

Both aluminum (Al) and sodium bicarbonate (NaHCO3) can react with an acid (such as hydrochloric acid, HCl) to produce a gas (carbon dioxide, CO2). Therefore, choice C is the correct answer. Choice A (Al) will react with an acid to produce hydrogen gas (H2), but not CO2. Choice B (Na2B4O7·10H2O, commonly known as borax) will not react with an acid to produce a gas.
