Write equations for the reactions of (i) iron with steam (ii) calcium and potassium with water |
|
Answer» (i) Equation for the reaction of iron with steam is given below: `underset("Iron")(3Fe(s))+underset("Steam")(4H_(2)O(g))to underset("Iron (II,III) oxide")(Fe_(3)O_(4)(s))+underset("Hydrogen")(4H_(2)(g))` (ii) Equation for the reaction of calcium with water is as follows: `underset("Calcium")(Ca(s))+underset("Water")(2H_(2)O(l))to underset("Calcium hydroxide")(Ca(OH)_(2)(aq))+underset("Hydrogen")(H_(2)(g))` (iii) Equation for the reaction of potassium with water can be written as: `underset("Potassium")(2K(s))+underset("Water")(2H_(2)O) (l)to underset ("Potassium hydroxide")(2KOH(aq))+underset("Hydrogen")(H_(2)(g))` |
