The big bang; that's what most scientists think.
Answer:
2 moles of MgCl2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
Mg + 2HCl —> MgCl2 + H2
Now, we can determine the number of mole MgCl2 produced from 4 moles of HCl as follow:
From the balanced equation above,
2 moles of HCl reacted to produce 1 mole of MgCl2.
Therefore, 4 moles of HCl will react to produce = (4 x 1)/2 = 2 moles of MgCl2.
Therefore, 2 moles of MgCl2 were produced from the reaction of 4 moles of HCl.
