Introduction:
A chemical reaction is the process of rearranging the atoms in reactants to create new and unique substances known as products (3). Substances are either a chemical element or compound, which cannot be broken down into simpler substances by normal chemical procedure (3). Reactants are substances that undergo specific changes in the process of a reaction while products are the final product of the reactants when the chemical reaction is completed. In a chemical reaction the least amount of energy needed is known as activation energy. Activation energy is the amount of energy required for a chemical reaction to undergo its operation (6). In mathematical expressions or equations the letter E is depicted as activation energy

For example, when coffee is boiled the taste becomes bitter.
There are six different types of chemical reactions, synthesis, combustion, decomposition, single displacement, double displacement and acid base. The synthesizing of a reactant, also known as a synthesis chemical reaction, is when a new chemical compound is being created into a more complex form than what it was before.
B + E + N ---> BEN
A combustion chemical reaction is when oxygen or O is joined with a different compound in order to form water and carbon dioxide. Combustion reactions release and produce heat meaning it is exothermic. Decomposition reactions are the reverse or complete opposite of a synthesis reaction. In a decomposition reaction a complex molecule is broken down into simpler forms. (9)
BEN ---> B + E +N
A single displacement reaction is when substances flip flop with one another in a compound. The key to single displacement reactions is the movement of electrons from one element to another. Elections are negativity charged particles and particles make up atoms. (9)
E + BN ---> EN + B
A double displacement reaction is when anions, a negativity charged ion, and cations, ions which contain more protons giving them a positive charge, of two separate molecules switch places creating two new sets of unique compounds. (9)
JA + CK ---> JK + AC
Finally the last type of chemical reaction is an acid base reaction. An acid
Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.
What is the appearance of reactant, Evidence of chemical reaction, and properties of a product?
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?
Introduction – A double replacement reaction is a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound. If you have the reactants of two reaction solution that you can determine the products. All you need to do is pair the positive parts of the compounds with the other compounds negative part. Once you find the products you can determine their phase of matter by using Table H. You can also use Table F to determine the solubility guidelines for aqueous solutions. If the product falls under soluble or exceptions to insoluble it is in the aqueous stare. If the product falls under
One type of chemical reaction, called combustion, involves the burning of various compounds and elements. Some substances are more
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.
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
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.
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.
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).
The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors.
In science a few days ago we made chemical rockets. That reacted with vinegar and baking soda. The chemical property that we invested was the chemical property of reactivity. We put 10mL of vinegar in the 30mL film canister. It made a couple of changes it fizzled, it raised, and made a pop sound when it exploded. The types of matter that is reacting are compounds baking soda is NaHCO3 vinegar is CH3COOH.
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.
A chemical reaction is a process by which atoms of one or more substances are rearranged to form a different substance. Six types of chemical reactions are Synthesis, Combustion, Decomposition, Single Replacement, Double Replacement, and Acid/Bases. Each of these does something different, some combine to make a new product and some break down to make new products. Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. A description of Synthesis reaction would be taking a mystery element, called “A” and combining it with “B” and the new product would be what you get when you combine those two elements (AB). An experiment you can do to help with your understanding of Synthesis is making slime because you are using multiple reactants(glue, borax, and water) to create a single new product(slime). Two real life examples of Synthesis reaction is water and your lungs. The product of Carbon mixed with Oxygen is CO2, which is found in your lungs. Water is a synthesis reaction because it is a product of Hydrogen and Oxygen (Anne Helmenstine, Synthesis Reactions and Examples, 2017).
Therefore, when baking soda and vinegar combine, they create a chemical reaction. A chemical reaction is a process that includes the rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. A chemical reaction is accompanied physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Chemical reactions are constantly occurring in the world around us. Everything from the rusting of an iron fence to the
