Answer : The HCl reactant is left over in the reaction and the left over amount of HCl is, 3.1 grams
Explanation : Given,
Mass of = 16.0 g
Mass of = 30.0 g
Molar mass of = 87 g/mole
Molar mass of = 36.5 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 1 moles of react with 4 mole of
So, 0.184 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
The excess moles of HCl = 0.822 - 0.736 = 0.086 mole
Now we have to calculate the mass of .
Therefore, the HCl reactant is left over in the reaction and the left over amount of HCl is, 3.1 grams
