nickel and zinc chloride
This is the reactivity series of metals.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
An element is one of the reactants, and a compound is the other reactant.
A single replacement reaction involve the replacement of an element with other in the molecule as in this model:A + B-C = A-C + B.
This is not a replacement reaction. And the silicon chloride is SiCl4.
The type of reaction that always has an element and a compound as reactants is a single displacement reaction, or a substitution reaction. These are of the form A + BC ---> AC + B.

A single-replacement reaction
This is the reactivity series of metals.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
You can identify a single replacement reaction because the reactants are a compound + an element. The products of a single replacement reaction are found by switching the element with another element in the compound. Metals switch with metals, non-metals switch with non-metals, and the most reactive element is always in the compound. A double replacement reaction can be identified because the reactants are always compound +compound. The products would also be two compounds but the elements would switch.
The products are iron (II) nitrate and copper.
An element is one of the reactants, and a compound is the other reactant.
Iron (II) nitrate and elemental copper.
Iron nitrate and metallic copper.
