Question

Write equations for the reactions of : (a) iron with steam (b) Ca & K with steam. (2)​

Answer 1

Answer:

Fe + H2O(Steam) --> FeO + H2

Ca + H2O(Steam) --> CaO + H2

K + H2O(Steam) --> KO + H2

(Though , Na and K can easily react with water only....There's no need of reacting them with steam)

Answer 2

Answer:

An equation for the reaction of :a) iron with steam

when a metal reacts with steam then the products formed are metal oxide and hydrogen gas

Metal + steam ______> metal oxide + hydrogen

3Fe(s)+4 H20 (g) steam ___> fe 304 (s) + 4H2(g)

calcium and potassium reacts with to give their respective hydroxides. The reaction are shown below

Ca + 2h20 _____>(a (oh2) +H2 + Heat

2k + H2o _____>2koh + H2 + heat
