Feb 13, 2021 · A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. Presented below: \[\ce{2HCl(aq) + Zn(s) → ZnCl2(aq) + H2(g)} onumber \] is an example of a single-replacement reaction.
A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. For example, \[\ce{2HCl(aq) + Zn(s) → ZnCl2(aq) + H2(g)}\] is an example of a single-replacement reaction.
Examples of Single-replacement Reaction. An example of a single-displacement reaction occurs when potassium (K) reacts with water (H 2 O). A colorless solid compound named potassium hydroxide (KOH) forms and hydrogen gas (H 2) is set free. The equation for the reaction is: 2 K (s) + 2 H 2 O (l) → 2 KOH + H 2 (g)
A single replacement reaction occurs when an element reacts with a compound to produce a new element and a new compound. There are two types of single replacement reactions: A metal replaces another metal that is in solution: A+BC → B +AC. Example: Zn+CuCl2 → Cu +ZnCl2.
You need to be able to recognize single replacement reactions AND be able to break a formula apart into proper cations and anions as well as write correct formulas. Here are several examples which are solved below: 1) ZnS + O 2 ---> 2) K + H 2 O ---> 3) Fe + HCl ---> 4) NaI + Br 2 ---> Example #1. How to figure out the right (or product side):
Example: AX + B → A + BX. Single replacement reactions are typically exothermic reactions due to the formation of a new bond in the products. This means that single-replacement reactions produce energy via heat /light instead of using up energy (like in endothermic reactions)
Feb 6, 2024 · A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is: A + BC → AC + B. In this general reaction, element A is a metal and replaces element B, also a metal, in the compound.
