Answer: [tex]Mg+2HCl\rightarrow MgCl_2+H_2[/tex]
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example: [tex]Fe_2O_3+3H_2O\rightarrow 2Fe(OH)_3[/tex]
[tex]2Mg+O_2\rightarrow 2MgO[/tex]
2. Double displacement reaction is one in which exchange of ions take place.
Example: [tex]FeS+2HCl\rightarrow FeCl_2+H_2S[/tex]
3. Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example: [tex]Mg+2HCl\rightarrow MgCl_2+H_2[/tex]
