nickel and zinc chloride
Single replacement reactions can be exothermic or endothermic, depending on the specific reactants and products involved. The heat change for each single replacement reaction must be evaluated individually to determine if it is exothermic or endothermic.
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.

Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
The products of this single replacement reaction are iron(II) nitrate and copper. The iron displaces the copper in the reaction, resulting in the formation of iron(II) nitrate and elemental copper.
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
The smallest possible number of products in a decomposition reaction is 2, where a single reactant breaks down into two separate products.
An element is one of the reactants, and a compound is the other reactant.
One can predict the products of chemical equations by understanding the types of reactions involved, such as synthesis, decomposition, single replacement, or double replacement. By knowing the reactants and their properties, one can use chemical rules and equations to determine the possible products that will form during the reaction.
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.
