1 Totally different from sulphur and oxygen
2 Similar to sulphur
3 Similar to oxygen
4 More similar to sulphur than oxygen
Explanation:
\({\rm{S + }}{{\rm{O}}_{\rm{2}}} \to {\rm{S}}{{\rm{O}}_{\rm{2}}}\) The properties of \({\rm{S}}\) and \({{\rm{O}}_{\rm{2}}}\) are totally different from \({\rm{S}}{{\rm{O}}_{\rm{2}}}\)

Statement A : Components of a homogeneous mixture cannot be separated by using physical methods. Statement B : Composition of homogeneous mixture is uniform throughout as the components react to form a single compound.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
In homogeneous mixture, the components completely mix with each other and hence the composition is uniform throughout. Formation of homogeneous mixture is a physical change as no chemical reaction occurs between the componenets and no new compound is formed hence the components can be separated by physical methods.
