Question

plzzzz don't spammmm​

Answer 1

Answer:

6)a- Because those are highly reactive metal and produce h+ ions

b) because it has free electron

7)a it may be wrong but i will try

fe+H20= FeO2+H^

b) Ca+H2o = CaO2 + H^

K+H2o= K2o +H

i don't surely this is ri8 but i only want 2 try

So don't mind

Answer 2

Answer:

Explanation:

6 b) because of present electron

7 a) M

etal + steam-------> metal oxide + hydrogen

metal oxide formula 3fe+3h2o------> fe3o4+4h2

7 b) #######calcium with water############

When a metal reacts with water( cold water or hot water) then the products formed are metal hydroxide and hydrogen gas.

Metal + steam --------> Metal hydroxide + Hydrogen

Calcium reacts with cold water to form calcium hydroxide and hydrogen gas:

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

##### potassium with water#######

Potassium reacts violently with cold water to form potassium hydroxide and hydrogen gas:

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.

sorry i dont remember the prop so thats why 6 a) is unanswered
