What are the five main types of chemical reactions and how can you predict the products?
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.
What is an example of a synthesis reaction that has important industrial applications?
The reaction of calcium oxide and carbon dioxide above is an example of a class of synthesis reactions that involve metal oxides combining with CO2 to produce the corresponding metallic carbonate. Magnesium metal and oxygen gas combine to form magnesium oxide: 2Mg + O2 → 2MgO.
What is combination reaction give example?
When a combination reaction occurs between a metal and a non-metal the product is an ionic solid. An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide.
How to predict the products of a chemical reaction?
Predicting Products of Chemical Reactions. Predicting Products of Chemical Reactions. Identify the type of reaction. Two elements: One compound: One compound, One element: Two compounds Hydrocarbon + O2 Synthesis Decomposition Synthesis or Single replacement Synthesis or Double replacement Combustion
Which is a typical example of a synthesis reaction?
2K(s) + Cl2(g) → 2KCl(s) As in these reactions, it’s common for a metal to react with a nonmetal. One typical nonmetal is oxygen, as in the everyday synthesis reaction of rust formation: 4 Fe (s) + 3 O2 (g) → 2 Fe2O3 (s) Direct combination reactions aren’t always just simple elements reacting to form compounds.
Which is an example of a predictable product?
Predicting Products. Certain synthesis reactions form predictable products: Combining two pure elements will form a binary compound. The product formed by reacting a metallic oxide and carbon dioxide will be a carbonate. Binary salts react with oxygen to form a chlorate.
Which is an example of a reaction with only one product?
Here, the sulfur oxide compound reacts with water to form a single product: So far, the reactions you have seen have only one product molecule on the right-hand side of the chemical equation. Let’s take a look at more complex reactions with multiple products. For example, the overall equation for photosynthesis:
