Abstract
This paper is about chemical reactions and chemical reaction types. All the data gathered was from conducting multiple experiments. Each experiment was performed carefully and analyzed to obtain the necessary information for the paper. That information included the four signs of a chemical change, the rnx type, and more.
Introduction
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.
When dealing with chemical reaction there are equations called chemical equations. Chemical equations give the reactants and products of a chemical reaction. When given just the reactants of an equation, you can predict the products by balancing each side of the equation. The products and reactions are separated by an rnx arrow
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?
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.
A chemical reaction is a process that involves change of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The key concepts of a chemical reaction are:
The objective of the experiment was to observe different reactions with different chemicals. The experiments emphasized on the chemical changes occurring in acids and bases as well as color changes and bubble formations. The experiments allowed for a better understanding of the undergoing chemical changes in mixtures. Some mixtures instantly changed colors while others were transparent or foggy. Some mixtures produced thick color that created solids called precipitates. Mixtures KI + Pb(NO3)2 and NaOH + AgNO3 both produce noticeable precipitates after a while. It was interesting to see the different acidic and base reactions like the fuchsia color formation in NaOH + phenolphthalein.

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.
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.
Chemical change results in one or more substances of entirely different composition. Chemical change requires a chemical reaction.
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.
There are five clues that help indicate if a chemical change occurs. The clues to a chemical change include a change of colour, the forming of a precipitate, the forming of gas bubbles, the production of heat or light, and if the change is difficult to reverse. In the chemical reactions lab, several chemical changes will occur. Participants must use this knowledge to decipher what change has occurred after the chemical
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).
There are thousands of chemical reactions that occur in an organism that make life possible. Most of these chemical reactions occur too slowly on their own. Enzymes are protein catalysts that speed up chemical reactions in a cell. Catalysts are not changed by the reactions they control, and are not used up during the reaction. Enzymes therefore, can be used over and over again. Enzymes are large complex proteins made by the cell and allow chemical reactions to take place at the temperature of the cell. These catalysts are needed in only very small amounts because a single enzyme molecule can complete the same reaction thousands of times in one minute.
