Question

Write equations for the reactions of
a) Iron with steam
b) Calcium and pottasium with water ​

Answer 1

Answer:

1. When a metal reacts with steam then the products formed are metal oxide and hydrogen gas. When red hot iron reacts with steam to form iron(II,III) oxide and hydrogen. ... 2K(s)+ 2H2O(l) --------> 2KOH(aq) + H2(g) + heat. In this reaction so much heat is produced get hydrogen gas formed catches fire and burns explosively

Answer 2

Answer:

The reactions are as follows :

(a) Fe(s) + H2O(g) -------> Fe3O4(s) + H2(g)

(b)Ca(s) + H2O(l) ----> Ca(OH)2(aq) + H2(g)

K(s) + H2O(l) ------------> KOH(aq) + H2(g)

Balanced :

(a)3Fe(s) + 4H2O(g) ---> Fe3O4(s) + 4H2(g)

(b)Ca(s) + 2H2O(l) --> Ca(OH)2(aq) + H2(g)

2K(s) + 2H2O(l) --------> 2KOH(aq) + H2(g)
