Answer 1

$\huge{\pink{\underline{\ulcorner{\star\: Answer \:\ star}\urcorner}}}$

Reaction 1

$\red{\underline{\star\:IRON \:WITH \:STEAM }}$

$3Fe \: + \:4H_2O \implies Fe_3O_4(aq)\:+ \:4H_2(g)$

Statement 1 : When iron react with water vapours it form iron oxide (ferrous oxide) and Hydrogen with heat(low).

Reaction 2

$\red{\underline{\star\: CALCIUM \:\&\: POTASSIUM \:WITH \:WATER}}$

$Ca \:+\: 2H_2O\implies Ca(OH)_2(aq)\: +\: H_2(g) \:+ \: Heat \:liberated\\ 2K\:+ \:2H_2O \implies 2KOH(aq)\:+\: H_2(g)+\: Heat\: liberated$

Statement 2 : When calcium react with it form calcium hydroxide with hydrogen gas and tramandous amount of heat liberated.


Statement 3 : When Potassium react with it form Potassium hydroxide with hydrogen gas and tramandous amount of heat liberated.

Note :
K refer Potassium
H refer Hydrogen
O refer Oxygen
Fe refer Iron
Ca refer Calcium

g = in a form of gas

aq = aqueous solution
