A Study On Chemical Reactions

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.

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.

When given similar looking substances, they can be distinguished by their chemical reactions. Baking soda can be noticed when it is contained in acidic ingredients and starts to bubble. Its chemical formula is NaHCO3. Baking powder is a combination of baking soda, calcium acid phosphate (a weak acid), and cornstarch; used in bing to generate bubbles. Its chemical formula is NaHCO3. When baking soda is reacted with red cabbage indicator, a color change usually occurs from pink to green. The chemical equation between vinegar and baking soda is NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq).

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.

Introduction Chemical reactions occur all around us, even in us. Millions of reactions occur in our bodies every day, let alone outside of out bodies (ChemHealthWeb.gov, 2015). Human bodies create energy by using glucose in a series of chemical reactions to release energy. This is called respiration and it occurs in all living cells. Some chemical reactions are visible such as oxidation.

Chemical reactions are either villains of society which create problems for human health or the environment; or they can be heroes, used to solve problems of the environment. An example of a chemical reaction that is harmful for humans and the environment would be the burning of fossil fuels that ultimately lead to acid precipitation. This posses large issues to ecosystems in lakes by raising their pH level. One way of solving the issue of acid rain in lakes is to add the base calcium hydroxide. This would be an example of a chemical reaction that is used to solve the problems in our environment. Another chemical hero would be preventing acid rain by converting unhealthy and damaging gases into ones that are harmless to the environment.

This causes the formation of new substances with new properties. Chemical reactions involve reactants which are chemicals that are present at the start of chemical reactions. Reactants are used up during the reaction and are the ingredients of the process. Products are chemicals that are produced during a chemical reaction and are known as the end result. After a chemical reaction has taken place, the outcome is chemical products.

This experiment will demonstrate a double-replacement action, as the two different compounds will trade elements to form two new compounds e.g NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2. However, this experiment will also involve a neutralisation reaction, when the same amount of acid and base are combined together, as it will neutralize the compound and produce salt, water (see equation) and an extra product of carbon dioxide. According to the hypothesis, as the concentration/amount of acid increases, the rate of reaction will also increase this is because as the reactant particles in the compounds will get more crowded in the compound, leading to a greater chance of particles colliding, therefore this means there is a higher chance that the molecules will complete the reaction quicker, which means the rate of reaction would be faster. But, this reaction occurs baking soda (sodium bicarbonate) has a sodium atom, a hydrogen atom, an oxygen atom and a carbon trioxide molecule, whereas vinegar (acetic acid) contains a hydrogen atom and an acetate ion. And when these compounds are combined the hydrogen atom in the vinegar accumulate with the hydrogen and oxygen atoms in the baking soda to form water (H2O), but while the acetate ion in the vinegar takes the sodium atoms and forms salt/sodium acetate. And now the carbon dioxide molecule is not connected with other chemical bonds, therefore comes forth as a

Reactions occur everywhere, and they may take decades, such as fossils, or only seconds, such as lighting a match to occur. “Chemical kinetics concerns the rates of chemical reactions” and what factors affects these rates (Iodine Clock, 2017). “Temperature, concentration, pressure of reacting gases, surface area of reacting solids and the use of catalysts are all factors which affect the rate of a reaction” (Bbc.co.uk, 2017). This is because they affect the reaction roles and yields of activation energy, product management and reactant management (William, 2017). This is accomplished by “making changes to the concentration, pressure or temperature of a reaction to alter the position of the equilibrium” (Bbc.co.uk, 2017).

Another thing portaging to this experiment is the chemical reactions do to lighting of the match. And a chemical reaction is a process that involves rearrangement of the molecular or ionic structure of

Chemical weathering occurs when a rock or building material is eroded and/or disintegrated by a chemical process. This will occur primarily when a water is mixed with a chemical. Chemical weathering will also often occur by water and in areas where warmer water or temperatures more frequently occur and are common (kidsgeo), as the process accelerates and thrives in these conditions. Often this process will occur in warmer seasons in the summer or spring to take advantage of the warmer weather in order to accelerate the process. There are three distinct types of chemical weathering that can occur: oxidation, hydrolysis, and carbonation. Oxidation will occur when a molecule will gain an extra oxygen molecule. A good example of this is rust (passel), which occurs when iron reacts with oxygen and it becomes iron oxide. So when a rock goes oxidised is becomes weaker and can break down easily as the extra oxygen has weakened its structure . Hydrolysis will occur when an extra water molecule is added. And carbonation will occur when water reacts with carbon dioxide to form a carbonic acid, which can hollow out rocks by breaking them down, leading to cave formations.
