Question
When Lead and Oxygen combine to form PbO and PbO2, then the ratio of Oxygen combining with a fixed weight of Lead is :Select an answerA1 : 2B2 : 1C1 : 1DNone of these
Solution
The answer to this question is A1 : 2.
Here's the step by step explanation:
-
When Lead (Pb) combines with Oxygen (O), it forms two compounds: PbO and PbO2.
-
In PbO, the ratio of Pb to O is 1:1. This means for every one atom of Pb, one atom of O is required.
-
In PbO2, the ratio of Pb to O is 1:2. This means for every one atom of Pb, two atoms of O are required.
-
Therefore, when comparing the amount of Oxygen that combines with a fixed weight of Lead in both compounds, the ratio is 1:2.
