The first equation looks like a double displacement reaction:
Ca(ClO)₂ + ? → HClO + ?
The first "?" must be a strong acid, because there is an H in the products. Let's use sulfuric acid. Then the balanced equation is
Ca(ClO)₂ + H₂SO₄ →2HClO + CaSO₄
The second equation also looks like a double displacement reaction:
HClO + ? → H₂SO₄ + ?
The first "?" must be a sulfate, because there is an SO₄ in the products. Let's use sodium sulfate. Then the balanced equation would be
2HClO + Na₂SO₄ → H₂SO₄ + 2NaClO
This equation works on paper, but it is wrong. The weak acid HClO will not react with any sulfate salt to form the strong acid H₂SO₄.
There is no correct answer to the second equation.
