Dec 3, 2020 · Get the definition of a single replacement reaction or single displacement reaction. Get examples of single replacement reactions and learn how to use the metal reactivity series to predict whether a reaction will occur and the products.
A single-replacement reaction is a chemical reaction in which one element replaces another in a compound. The general equation is A + BC → AC + B Examples are Zn + 2HCl → ZnCl₂ + H₂, where Zn replaces H in HCl, and F₂ + 2NaCl → 2NaF + Cl₂, where F replaces Cl in NaCl.
Single-Replacement Reactions. 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: \[\ce{A} + \ce{BC} \rightarrow \ce{AC} + \ce{B}\nonumber \]
Feb 13, 2021 · A single-replacement reaction replaces one element for another in a compound. The periodic table or an activity series can help predict whether single-replacement reactions occur. A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.
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.
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)
What are single-replacement reactions? Single-replacement reactions are reactions in which one element replaces another in a compound; Example: AX + B → A + BX. Single replacement reactions are typically exothermic reactions due to the formation of a new bond in the products.
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.
May 1, 2013 · In a single-replacement reaction, one element takes the place of another similar element in a compound. Common types of single-replacement reactions include metal replacement, hydrogen replacement, and halogen replacement.
