Question

What are the reaction types for the following?

1) Nal → Na + I₂

2) C ₂H₂ + O₂ → CO₂ +H₂O

3) Co+ CuSO₄ → CoSO₄ + Cu

4) SO₂ +H₂O → H₂SO₃

5) CaBr₂ +NA₂ CO₃ → CaCO₃ +NaBR

Answer 1

1. decomposition

2. combustion

3.single replacement

4. combination

5. double replacement

Step-by-step explanation:

1. one compound is split into 2 elements

2. co2 and h20 was the product of the reaction

3. cu is replaced with co

4. 2 compounds become one compound

5. ca is replaced with na and na is replaced with ca
