How do you write a single replacement reaction?
A single replacement reaction occurs when one element replaces another in a single compound. This type of reaction has the general equation: A + BC → B + AC. In this equation, A represents a more reactive element and BC represents the original compound.
What’s an example of single replacement?
Single Replacement Reactions A single replacement reaction occurs when one element replaces another in a single compound. An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
How is single replacement used in everyday?
Examples of Single Replacement Chemical Reactions zinc + hydrochloric acid —> zinc chloride and hydrogen gas. zinc + silver nitrate —> zinc nitrate and silver metal. iron + copper nitrate —> iron nitrate and copper metal. bromine + potassium iodide —> potassium bromine and iodine.
What is single replacement?
A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound. The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound.
What types of single replacement reactions are there?
There are three main types of single replacement reactions determined by the reactivity series:
- Metal Replacement: where metal will displace another metal.
- Hydrogen Replacement: where hydrogen gas is produced through displacement by a metal.
- Halogen Replacement: when a halogen participates in displacement.
How do you know if it’s a single replacement reaction?
To determine whether a given single replacement will occur, you must use an “Activity Series” table. If the metal or the halogen is above the element it will replace based on the activity series, a single displacement reaction will occur.
How do you know if a reaction is single or double replacement?
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.
