Question Analyse the figure. Identify Gas A. Also, write the word equation of the chemical reaction.
Answer:
By analysing the figure, it is found that there will be a chemical reaction inside the test tube between dilute HCl and Fe.
2HCl + Fe → FeCl2 + H2 ↑
So the reaction forms Iron Chloride (FeCl2) and the gas above will be Hydrogen (H2).
Hydrochloric Acid + Iron filing → Iron Chloride + Hydrogen (g)
Thus, Gas A = Hydorgen
