Question

Na + H₂SO4 → Na₂SO4 + H₂Ca + Fe Cl3 → CaCl2 + FeC + O₂ → CO​

Answer 1

Ответ:

1)2Na+H2SO4 =Na2SO4 +H2

2)3Ca+2FeCl3=3CaCl2 +2Fe

3)2C+O2=2CO

Answer 2

It seems like you've provided a list of chemical reactions in a shorthand notation. Let's break down each reaction and balance the chemical equations properly:

1. Sodium reacts with sulfuric acid: Na + H₂SO₄ → Na₂SO₄ + H₂

2. Calcium reacts with iron(III) chloride: Ca + FeCl₃ → CaCl₂ + Fe

3. Calcium carbonate decomposes: CaCO₃ → CaO + CO₂

Here are the balanced chemical equations for each reaction:

1. 2Na + H₂SO₄ → Na₂SO₄ + H₂
2. 3Ca + 2FeCl₃ → 3CaCl₂ + 2Fe
3. CaCO₃ → CaO + CO₂
