Answer : The number of moles of [tex]Ca(OH)_2[/tex] required are, 0.6 mole.
Explanation : Given,
Moles of HI = 1.2 moles
The given balanced chemical reaction is,
[tex]2HI+Ca(OH)_2\rightarrow CaI_2+2H_2O[/tex]
From the balanced chemical reaction, we conclude that
As, 2 moles of [tex]HI[/tex] react with 1 mole of [tex]Ca(OH)_2[/tex]
So, 1.2 moles of [tex]HI[/tex] react with [tex]\frac{1.2}{2}=0.6[/tex] mole of [tex]Ca(OH)_2[/tex]
Therefore, the number of moles of [tex]Ca(OH)_2[/tex] required are, 0.6 mole.
