Final answer:
The chemical formula for baking soda, given the atomic ratio of sodium, hydrogen, carbon, and oxygen is NaHCO3, which is option C. Baking soda is widely used in culinary applications and has various household uses. C. NaHCO3.
Step-by-step explanation:
The chemical formula for baking soda is determined by the atomic ratio provided, which is 1 part sodium (Na), 1 part hydrogen (H), 1 part carbon (C), and 3 parts oxygen (O). This corresponds to sodium bicarbonate which has the chemical formula NaHCO3. Thus, the correct answer is C. NaHCO3. Sodium bicarbonate, commonly known as baking soda, is used in many cuisine applications, including as a leavening agent in baked goods. When it reacts with an acid, it produces carbon dioxide, causing the batter to rise.
Baking soda is also used for various purposes, such as in foods to regulate acid balance and in laundry to enhance detergent efficiency by interacting with other ions in water.
