Identify the balanced combination equation. Cl205 + H2O → 2HCIO3
2Fe(OH)3 - Fe2O3 + 3H20
C1205 + 3H20 HCIO3
2Fe(OH)3 — 2FeO3 + 3H20

Cl₂0₅ + H₂O → 2HCIO₃

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

Given

Chemical equations

Required

The balanced combination equation

Solution

There are several types of reactions that can occur

Synthesis/combination : 2 elements combine to form a single product

A + B⇒AB

Decomposition: One compound breaks down into 2 components

AB⇒A + B

Decomposition is the reverse of syntesis reaction

A balanced equation shows that the number of atoms from the reactant and product sides is the same

The chemical equations that fulfill the two things above (combined and balanced reactions) are:

Cl₂0₅ + H₂O → 2HCIO₃

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

the answer is option a.
