30 moles of HCl
15 moles of Cl2 = 30 moles of Cl-
since H in in excess then the moles of Cl- = HCl

the basic reaction is
H2 + Cl2 ----> 2HCl
Thus, 1 mole of Chlorine gas and 1 mole of H2 give 2 moles of HCl.
When hydrogen is in excess, Cl2 is the limiting reagent i.e. the amount of HCl formed is governed by the amount of Cl2 gas. Hence by using the ratio 1:2....15 moles of Cl2 give 30 moles of HCl.
ANS:30 moles of HCl are formed.
1063.5 grams of HCl are formed.
{Using molar mass of Cl= 35.45 g/mol}

1) Cl2+H2--->2 HCL
so 1mole of Cl2 produces by this way 2 moles HCl
and 15 moles of Cl2 15*2 =30moles HCl
2) molar mass of HCl = 35.5+1=36.5g
so 30moles have a mass of 36.5*30=1090g

Cl2 + H2 = 2HCl
therefore, 30 moles of HCl are formed.
1080 grams or 1.08 kg of HCl is formed
