Answer 1

Answer:

Heyy, here's your answer.

1. Magnesium ribbon should be cleaned before burning in air so that to remove the thin layer of magnesium oxide which is formed on the ribbon which will prevent it from combusting
2. 2H + Cl2 = 2HCL and 3BaCl2 + Al2(So4)3 = 3BaSO4 + 2AlCl. and Na + H20 = NaOH + H2
3. BaCl2 + NaSO4 = BaSO4 + NaCl
4. NaOH + Hcl = NaCl + H2

Hope this helps.

Next time please be clear with your questions since I was not able to understand it and please offer more points as well, since it takes time to write a detailed answer.

Thank you for your attention
