Answer:
HCl is the limiting reactant
Explanation:
To find the limiting reactant of a reaction we must find the moles of each one as follows:
Moles Mg (Molar mass: 24.305g/mol)
4.8g Mg * (qmol / 24.305g) = 0.20 moles Mg
Moles HCl (Molar mass: 36.46g/mol)
6.00g HCl* (1mol / 36.46g) = 0.165 moles HCl
Based on the chemical reaction, for a complete reaction of 0.20 moles of Mg are necessaries:
0.20 moles Mg * (2mol HCl / 1mol Mg) = 0.40 moles HCl
As there are just 0.165 moles of HCl:
HCl is the limiting reactant
