Name a gas which is always produced when a reactive metal reacts with a dilute acid. Write a chemical equation supporting your answer.
Hydrogen gas ( H 2) is produced as a byproduct when dilute acids( H 2 SO 4, HCl) reacts with reactive metals such as Alkaline metal or Alkaline earth metal ( Mg , Al , Zn . . .) For example: Reaction of Sodium ( N a) with Hydrochloric acid ( HCl), Hydrogen gas ( H 2) is produced as a byproduct. Chemical reaction is as follows. 2 Na ( s ) Sodium + 2 HCl ( aq ) Hydrochloric acid → 2 NaCl ( s ) Sodium chloride + H 2 ( g ) Hydrogen When Aluminium ( Al) reacts with dilute Sulphuric acid ( H 2 SO 4), Hydrogen gas ( H 2) is produced as a byproduct. Chemical reaction is as follows. Al ( s ) Aluminium + 2 H 2 SO 4 ( aq ) Sulphuric acid → Al 2 ( SO 4 ) 3 ( s Aluminium sulphate ) + 3 H 2 ( g Hydrogen ) Q. (a) What happens when calcium reacts with water? Write the chemical equation of the reaction of calcium with water. (b) Write the chemical equation of the reaction which takes place when iron reacts with dilute sulphuric acid. What happens when the gas produced is ignited with a burning matchstick?
Which gas is produced when dilute hydrochloric acid reacts with a reactive metal? Write the chemical reaction when iron reacts with dilute H2SO4
Write the chemical equations for the following activities. (a) NaOH solution was added to HCI solution. (b) Zinc dust was added to dilute H 2 S O 4 (c) Dilute nitric acid was added to calcium oxide. (e) Carbon dioxide gas was passed through KOH solution. (f) Dilute HCI was poured on baking soda.
