Question

in feso4, the oxidation number of s is a +6 b +2 c -2 d +4 continue question 6 of 6

Explanation:

Step1: Determine oxidation numbers of known elements

In \(FeSO_4\), the oxidation number of \(Fe\) (iron) is \(+ 2\) (as it is in the \(Fe^{2+}\) state in ferrous sulfate), and the oxidation number of \(O\) (oxygen) is \(-2\). Let the oxidation number of \(S\) be \(x\).

Step2: Use the rule that the sum of oxidation numbers in a compound is zero

For \(FeSO_4\), we have the equation: \((+2)+x + 4\times(-2)=0\).
Simplify the equation: \(2 + x-8 = 0\), which becomes \(x-6 = 0\).
Solving for \(x\), we get \(x = +6\).

Answer:

A. +6
