Question

In the single displacement reaction of HCl and magnesium, how many grams of magnesium chloride would be produced if 1.05g of magnesium were consumed

Answer 1

4.16g of MgCl2

Step-by-step explanation:

First, let us generate a balanced equation for the reaction:

Mg + 2HCl —> MgCl2 + H2

Molar Mass of Mg = 24g/mol

Molar Mass of MgCl2 = 24 + (2x35.5) = 24 + 71 = 95g

From the equation,

24g of Mg produced 95g of MgCl2.

Therefore, 1.05g of Mg will produce = (1.05x95)/24 = 4.16g of MgCl2
