Based on my understanding, I will explain how I found out the limiting reagent in this problem. Please tell me if my explanation is correct or not.

Equation : Zn + 2HCl - ZnCl2 + H2

To determine the limiting reagent, we need to see how much ZnCl2 will Zn and HCl produce separately.

So,

65.4g of Zn gives 136.4g of ZnCl2

Thus 1g of Zn will give 2.08g of ZnCl2

Now,

73g of HCl gives 136.4g ZnCl2

Thus 1g of HCl will give 1.86g of ZnCl2

Now the limiting reagent is the one which produces the least amount of ZnCl2

Thus in this equation, HCl is the limiting reagent.

please tell me if my explanation is correct or not.

Please help!!!!
