Question

Please answer the correct answers of these questions.​

Answer 1

Answer:

1. 2K + 2H2O --- 2KOH + H2

2. Pb + 2AgNO3 --- Pb(NO)3 + 2Ag

3. 2Na + CuSO4 --- Na2SO4 + Cu

4. CuSO4 + Ag --- No reaction (Ag is less reactive than Cu)

5. Mg + 2HCl --- MgCl2 + H2

6. Cu + 2HCl --- CaCl2 + H2

7. Zn + MgSO4 --- No reaction (Mg is more reactive than Zn, so Zn can't replace magnesium from its salt)

8. 2K + Br2 --- 2KBr

9. Al + NaCl --- No reaction

10. 6K + Al2(SO4)3 --- 3K2SO4+ 2Al

11. 2Al + 3H2SO4 --- Al2(SO4)3 + 3H2

(Reaction is mainly dependent on reactivity)
