Answer:
D.) decomposition
Explanation:
A.) is incorrect. In double-displacement reactions, the cation of one compound is swapped with the cation of another.
These reactions have the general structure: AB + CD -----> AD + BC.
B.) is incorrect. In single-displacement reactions, the an element within a compound is swapped with another element.
These reactions have the general structure: AB + C -----> AC + B.
C.) is incorrect. In synthesis reactions, two or more elements/compounds are combined to create a new and larger compound/molecule.
These reactions have the general structure: A + B -----> AB.
D.) is correct. In decomposition reactions, a compound/molecule is broken down into smaller elements/compounds. In the given reaction, water (H₂O) separates into its respective elements, hydrogen (H₂) and oxygen (O₂).
These reactions have the general structure: AB -----> A + B
Answer
let the oxidation of sulphur is x
2(+1)+x+4(-2)=0
+2+x-8=0
+2-8+x=0
-6+x=0
x=6
Explanation:
i hope this will help you:)
<span>You can't substitute that. Substitution is a reaction between acid and metal. Acid+metal ---> salt+H2
example : H2SO4+Al ---> Al2(SO4)3+H2 so,substitution of hno3 solution for 3M h2so4 is not possible</span>
