Answer:
1) 1.6 moles of HCl
Step-by-step explanation:
1) 1.6 moles of HCl 
 
2) 7.0 moles of HCl 
 
3) 2.4 moles of hydrogen 
 
4) 0.96 moles of HCl 
 
Explanation: 
 
The balanced chemical equation is: 
 
 
 
According to stoichiometry : 
 
1 mole of require = 2 moles of 
 
0.8 moles of will require= of 
 
3.5 moles of will require= of 
 
According to stoichiometry : 
 
2 moles of produce = 1 mole of 
 
4.8 moles of will require= of 
 
According to stoichiometry : 
 
1 mole of are produced by = 2 moles of 
 
0.48 moles of are produced by = of
