Question

What happens when Al reacts with NaOH? Write chemical reaction * Name the gas produced when metals react with acids. How will you test the presence of this gas? * Based on your knowledge of displacement reactions, tell whether following reactions will take place or not? Complete the reactions by writing products. a) Zn+ CuSO4 ---> b) Cu + FeSO4---> c) Mg+ CuSO4 ---> d) Fe + ZnSO4---> e) Ca + FeSO4---> f) Mg + NaCl---

Answer 1

Answer:

1. zn+CuSO4----->ZnSO4 + Cu
2. Cu+FeSO4----->CuSO4 + Fe
3. Mg +CuSO4----->MgSO4+Cu
4. Fe+ZnSO4------>FeSO4 +Zn
5. Ca +FeSO4----->CaSO4+Fe
6. Mg+2NaCl---->MgCl2+2Na

When sodium hydroxide ts with Aluminium then it gives sodium aluminate(Na2AlO2) and water.

May this will help you.
