Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R).
Assertion (A) : Hydrogen combines with oxygen to form two compounds namely, water and hydrogen peroxide.
Reason (R) : The above example is in accordance with law of multiple proportion.
In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- AIf (A) & (R) both are correct and (R) is the correct explanation of (A).
- BIf (A) & (R) both are correct but (R) is not the correct explanation of (A).
- C(A) is correct but (R) is incorrect.
- D(A) & (R) both are incorrect.
Correct answer
A. If (A) & (R) both are correct and (R) is the correct explanation of (A).
Step-by-step solution
Assertion (A):
Hydrogen combines with oxygen to form two compounds, water ((\mathrm{H}}_{2}\mathrm{O})) and hydrogen peroxide (\left(\mathrm{H}}_{2} \mathrm{O}}_{2}\right)).
- This is correct because hydrogen and oxygen combine to form two distinct compounds.
Reason (R):
This example follows the law of multiple proportions, which states that if two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other are in simple whole number ratios.
- This is also correct, as the ratio of oxygen in (\mathrm{H}}_{2} ) to (\mathrm{H}}_{2} \mathrm{O}}_{2}) is 1:2, consistent with the law of multiple proportions.
