CaO+H2O=...Ca+H2O=...H+I=...HCI+KOH=...KI+CI2=...

Question

CaO+H2O=...
Ca+H2O=...
H+I=...
HCI+KOH=...
KI+CI2=...

Answer 1

CaO + H2O = Ca(OH)2
Ca+2H2O= Ca(OH)2 + H2
&???H2+I2=2HI
KOH + HCI = KCI + H2O
2KI+CL2 = 2KCl + I2 

Answer 2

CaO+H2O=Ca(OH)2
Ca+2H2O=Ca(OH)2+H2
H2+I2=2HI 
HCI+KOH=KCl+H2O
2KI+Cl2=2KCl+I2
