### Law of Multiple Proportions Quiz #### Question 2.3 **Which of the following pairs shows the law of multiple proportions?** - ○ All of these - ○ C₃H₇Cl and C₃H₇N - ○ CuCl₂ and MgCl₂ - ○ FeO and Fe₂O₃ You may select only one answer. [Previous button] --- In this multiple-choice question from an educational website on chemistry, students are asked to identify which pair of chemical compounds demonstrates the law of multiple proportions. The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. ### Options Explained: 1. **All of these**: Asks students to consider if all the given pairs illustrate the law of multiple proportions. 2. **C₃H₇Cl and C₃H₇N**: These are two different compounds containing carbon, hydrogen, and one other element (chlorine and nitrogen, respectively). 3. **CuCl₂ and MgCl₂**: These are compounds with the similar format but different metals (copper and magnesium), paired with chlorine. 4. **FeO and Fe₂O₃**: These are two oxides of iron, differing in the ratios of oxygen to iron. ### No Graphs or Diagrams: The image consists only of text and does not include any graphs or diagrams.
