Explain types of chemical reaction by giving one example each.
Answers
Explanation:
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
Answer:
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
Combination- An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in the air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide.
Decomposition - A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen and the breakdown of water to hydrogen and oxygen
Single-replacement - 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. ... An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O)
Double-replacement - An example of a double replacement reaction is the reaction between silver nitrate and sodium chloride in water. Both silver nitrate and sodium chloride are ionic compounds. Both reactants dissolve into their ions in an aqueous solution
Combustion - Combustion of methane. CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)
A combustion reaction occurs when a substance reacts quickly with oxygen (O2). ... The products of a complete combustion reaction include carbon dioxide (CO2) and water vapor (H2O). The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is: Fuel + O2 → CO2 + H2O
