1.	What happens when- Aluminium reacts with sulphuric acid.- Iron react with atmospheric moisture (H2O)
Answer» Aluminum(Al)reacts with sulfuric acid,H2SO4, which is theacidin an automobile batteries, according to the equation : 2Al + 3H2SO4》Al2 (SO4)3 + 3H2 if 20.0 grams Al is put into a solution containing 115 g ofH2SO4. The reaction ofaluminumwith dilutesulfuric acidwill producealuminumsulfate and hydrogen gas b)Iron metal reacts in moist air by oxidation to give a hydrated iron oxide. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. Thisprocessis called rusting. Finely divided iron powder is pyrophoric, making it a fire risk
