Final answer:
The empirical formulas of baking soda, salt, sugar, and vanillin are NaHCO3, NaCl, C12H22O11, and C8H8O3 respectively, making the correct answer a) NaHCO3, NaCl, C12H22O11, C8H8O3.
Step-by-step explanation:
The empirical formula of a compound represents the simplest whole-number ratio of the elements within that compound. The empirical formulas of some common household substances are as follows:
- Baking soda - The empirical formula for baking soda, also known as sodium bicarbonate, is NaHCO3.
- Salt - Common table salt is comprised of sodium and chlorine in a 1:1 ratio, giving it the empirical formula NaCl.
- Sugar (sucrose) - The empirical formula for sucrose is C12H22O11, indicating it is composed of carbon, hydrogen, and oxygen.
- Vanillin - The compound responsible for the flavor of vanilla has an empirical formula of C8H8O3.
Based on the mentioned empirical formulas, the correct answer is a) NaHCO3, NaCl, C12H22O11, C8H8O3.
