Background information
The diverse types of chemical reactions include Combination Reaction, Decomposition Reaction, Displacement Reaction and Oxidation Reaction.
Combination reaction is a reaction where two reactants are combined into one product (Helmenstine, 2014). An example of this in everyday life is when we digest food in our stomachs, the acid in the stomach reacts with the molecules contained within the food and breaks them down.
A decomposition reaction is a type of chemical reaction where one reactant yields two or more products (Helmenstine, Thought Co, 2017). An example of this this the electrolysis of water into oxygen and hydrogen gas.
Single displacement reactions are reactions where one reactant replaces part of the other (Helmenstine, Thought Co, 2014). The elements with higher reactivity replaces the elements with lower activity, an example of this is the statue of liberty that is made from iron and coated with copper, the copper started reacting with air and a bluish green coating is formed. This coating reacts with the iron inside and a single replacement occurs and the outside copper is replaced back (Vista, 2017).
Oxidation reaction is the loss of electrons during a reaction by a molecule, atom or iron (Helmenstine, Thought Co, 2017). An example in everyday life is the formation of rust on a metal surface.
A chemical reaction takes place using displacement reaction between a metal and acid, for example when the hydrogen and magnesium react the
The study of the quantitative relationships between the amounts of reactants used and the amounts of products formed by a chemical reaction is called stoichiometry.
A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge.
In the study of chemical reactions, chemistry students first study reactions that go to completion. Inherent in these familiar problems—such as calculation of theoretical yield, limiting reactant, and percent yield—is the assumption that the reaction can consume all of one or more reactants to produce products. In fact, most reactions do not behave this way. Instead, reactions reach a state where, after mixing the reactants, a stable mixture of reactants
Reactants collide with each other so new bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make new products
One type of chemical reaction, called combustion, involves the burning of various compounds and elements. Some substances are more
Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.
What is the appearance of reactant, Evidence of chemical reaction, and properties of a product?
Neither matter nor energy is created or destroyed in a chemical reaction only changed. This experiment is a decomposition reaction a more complex substance breaks down into its more simple parts. One reactant yields 2 or more products.
A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products. There are many different types of chemical reactions. Scientist have classified the many different reactions into categories. The five major categories are combination or synthesis reaction, decomposition reaction, displacement or replacement reaction, acid base reactions, and combustion
Introduction : Chemical reactions are a process that involves, rearranging the molecular structure of substances to create new ones. There are about 5 types of reactions, however, the 3 most significant types are synthesis, (e.g. 2Na + Cl2 → 2NaCl); decomposition (CaCO3 → CaO + CO2); and finally combustion. Combustion is a rapid chemical combination of a substance (fuel) with oxygen, including the production of heat and light (e.g. CH4 + 2O2 → CO2 + 2H2O). In these types of reactions, bonds are broken and then formed to create the end product, which all requires the use or release of energy.
A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

A chemical reaction is a process in which elements or compounds react with one another to create new or different substances. There are two parts to a reaction. Those two parts are the products and the reactants. The reactants are the chemicals or chemical compounds that are going through the reaction itself. The products are chemical elements or chemical compounds that are produced as a result of the reactant or reactants reacting. There are four key indications that there’s a chemical reaction is taking place. Those four signs include a change in color and/or odor, formation of a precipitate or a gas, the release or absorption of energy (light, heat, electricity), and if the reaction is irreversible. Along with this information, there are ways to predict the products of a reaction.
Chemical reactions make new things by rearranging other things. In a chemical reaction, the main change that occurs relates to the way atoms are bonded to each other, in order to change those connections, bonds must be broken and new bonds be formed.
There are now many classification systems to classify the different types of reactions. These include decomposition, polymerization, chain reactions, substitute reactions, elimination reactions, addition reactions, ionic reactions, and oxidation-reduction reactions.
