Many metals undergo a single displacement reaction with hydrogen chloride (a strong acid, HCl). One example is magnesium, Mg. The products are hydrogen gas, H2, and magnesium chloride, MgCl2. Write the balanced single displacement reaction with the simplest whole number coefficients.

The balanced single displacement reaction with the simplest whole number coefficients is as follows: Mg + 2HCl → H2 + MgCl2

SINGLE DISPLACEMENT REACTION:

Mg(s) + 2HCl(aq) →  MgCl2(s) + H2(g)  

Explanation:

Many metal undergo displacement reaction . The most reactive metal will displace the less reactive metal from it compound.  A single displacement reaction is a reaction in which one element displaces another in it compound.

Many metal undergo displacement reaction with hydrogen chloride . One example is magnesium. Magnesium will  displace hydrogen in hydrogen chloride because it is more reactive than hydrogen. The displacement reaction is as follow

Mg(s) + HCl(aq) →  MgCl(s) + H2(g). The balanced equation with the simplest whole number ratio is as follows

Mg(s) + 2HCl(aq) →  MgCl2(s) + H2(g)  

the correct answer is a
