Hydrogen and oxygen combine to form two ...

Hydrogen and oxygen combine to form two compounds, water and hydrogen peroxide. If the percentage of oxygen is 88.89 in water and 94.12 in hydrogen peroxide, show that the data support law of multiple proportions.

Text Solution

AI Generated Solution

To demonstrate that the data supports the law of multiple proportions, we will follow these steps: ### Step 1: Understand the Law of Multiple Proportions The law of multiple proportions states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element will be in a ratio of small whole numbers. ### Step 2: Calculate the Percentage of Hydrogen in Each Compound 1. **For Water (H₂O)**: - Given percentage of Oxygen = 88.89% ...

    This law was proposed by Dalton in 1803 . According to this law , if two elements combune to form more than one compounds ,the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole number. For exemple, hydrogen combines with oxygen to form two compounds ,namely, water and hydrogen peroxide. Here, the masses of oxygen (i.e, 16g and 32g) which combine with a fixed mass of hydrogen (2g) bear a simple raio, i.e, 16 :32 or 1 :2 . An element forms two oxides .In one oxide ,one gram of the oxide containd 0.5g of the element. In another oxide, 4g of the oxide contains 0.8g of the element . Show that these data confirm the law of multiple proportion.
