Answer:
Theoretical yield of hydrogen is 1.11 g
Explanation:
Balanced equation, 
As Mg remain present in excess therefore HCl is the limiting reagent.
According to balanced equation, 2 moles of HCl produce 1 mol of
.
Molar mass of HCl = 36.46 g/mol
So, 40.0 g of HCl =
of HCl = 1.10 moles of HCl
Hence, theoretically, number of moles of
are produced from 1.10 moles of HCl = 
Molar mass of
= 2.016 g/mol
So, theoretical yield of
= 
Answer:
Lithium has 3 protons, 4 neutrons, 3 electrons, and its mass is 6.941 u
hydrogen is the lightest element in the periodic table
the correct answer is dissapate...but it is
not here so i think relativly the answer is destroy
Bc it’s the only group that distinguishes amino acids from one another’s
