Chemical Reactions And The Chemical Reaction

Chemical reactions are significant in our everyday lives. Combustion reactions help release energy to heat our homes and move our vehicles, oxidation-reduction reactions keep the batteries in our cell phones and laptops functioning and acid-base reactions take place when cleaning your oven. Not all reactions happen at the same speed. The speed at which a chemical reaction proceeds is known as the rate of reaction. Chemical reactions that proceed quickly, including explosion and combustion reactions are said to have a fast rate of reaction. Chemical reactions that proceed slowly,

Introduction: Chemistry happens everywhere, not just in a lab. Matter interacts to form new substances through a process called a chemical reaction. Your body lives and grows because of chemical reactions, whether by taking medicine or even a breath. A chemical reaction is defined as the process that involves rearrangement of the ionic structure of a substance. A reaction rate is how fast or slow a reaction takes place. Chemicals that proceed quickly have a fast reaction rate, whereas slowly proceeding chemicals have a slow reaction rate. There are many ways to increase the reaction rate of chemicals, for example temperature. If the temperature of the substance is increased, the particles would have higher kinetic energy resulting in more & more collisions. A greater proportion of collisions results in a reaction. Magnesium and Hydrochloric Acid are the two chemicals investigated throughout. Magnesium is an important supplement in the human body as well as its uses in many lightweight products such as car seats, luggage as well as fireworks and sparklers. Hydrochloric Acid can be found in the human body as a digestive acid.

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?

This is a simple equation that doesn’t properly prove the reaction. It is very complex and starts with this:

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:

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).

The reaction rate for this is slow at room temperature. The definition of reaction rate is the rate of change in concentration of either reactants or products. It is dependent on the concentration of the reactants and on the temperature. In a rate law, a mathematical expression, the relationship between the reaction rate and the concentrations of reactants can be demonstrated. For example, the rate law for the rate of decrease in concentration of bromate ion would be:

Chemical formulas indicate how new compounds are formed by chemical combinations of other compounds. To understand reactions, a person should be able to denote the elements from which compounds are formed. By knowing how to write a proper chemical formula and equation, then a person is able to determine formula and molecular weights, percentage composition, the moles, and empirical formulas. A chemical formula tells you the correct ratio of each element in the compound and the type of properties it will have. Combinations of the same element, but in different ratios produce different reactions; the chemical makeup of each substance.

A chemical reaction is a chemical change which forms new substances, such as compounds. Common chemical reactions include a candle burning, a nail rusting. *Physical changes reposition molecules but do not affect their internal structures. Physical changes you may already know of are, scrambling eggs, boiling water and even slicing an apple. Where as a chemical changes result in the creation of different chemical substances at the molecular level.

Our society today consists of many natural processes of reactions that involve rates. The rate of a reaction is the speed at which a reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a higher rate. Some reactions take hundreds, maybe even thousands, of years whilst others can happen in less than one second. The rate of reaction also depends on the type of molecules that are combining. If there are low concentrations of an essential element or compound, the reaction will be slower.

. There are four reactions that took place in this experiment. The first reaction is a redox reaction. When the Nitric acid was added to the copper wire in the beaker electrons were transferred from copper to nitrogen. The second reaction that took place is the double replacement precipitation reaction. This occurred when NaOH was added. Both the hydroxide and the nitrate ions exchanged and the copper hydroxide ions precipitated forming a solid. When the solution was heated, decomposition took place. The hydroxide ions in the copper hydroxide broke apart and left one oxygen atom which combined with copper to form copper oxide solid. The last reaction was the acid base reaction. This occurred when Sulfuric acid was added, the sulfate

A chemical reaction is the process in which atoms of the same or different elements form a new substance by rearranging themselves. The rate of reaction refers to the speed at which a chemical reaction proceeds. The rate of almost every chemical reaction can be sped up or slowed down by adding another variable. Factors such as, temperature, concentration of reactants, surface area, agitation and catalysts affect the rate of a chemical reaction. Increasing the temperature of a chemical reaction will usually speed up the rate of that reaction by causing the molecules to move faster. The two effects of increasing temperature are greater collision intensity and more frequent collisions.

A chemical reaction is the interaction of two or more chemicals that produces a new chemical compound, most reactions require an increase in temperature, pressure, surface area, concentration or the inclusion of a catalysts to speed up the rate of reaction. Chemical reactions can be found in everyday life, without many of us knowing. Either it be a soluble tablet in water, or photosynthesis in a plant. The prerequisites for a reaction are known as the 'Collision Theory '. As stated by M. Ferguson (2016), 'For a reaction to occur, particles must collide, with sufficient energy (also known as activation energy) in the correct orientation to break the existing bonds between the particles '.
