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?

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

3. The “new” substances that were formed as a result of chemical change were many. When I took the candle and lit it, it burnt and formed smoke. When I took the wooden split and lit the paper on fire, the color around the green paper changed to be brown, burnt and changed into ashes. Also, I poured Hydrochloric acid and magnesium ribbon in a test tube and it started bubbling and it heated up in the bottom.

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.

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.

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 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 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.

There are six types of chemical reactions. One of them is a combustion reaction, where oxygen combines with another element to form water and carbon dioxide. In addition, this is an exothermic reaction which produces heat, (CH4 + 2O2 → CO2 + 2H2O). The second type is the synthesis reaction, when two or more compounds combine to form one, (X+Y → XY). In contrast, decomposition reaction involves complex molecules broken down into simpler ones, (AB → A + B). The fourth reaction is the single replacement, a reaction where one reactant exchanges places with another compound, (AB + X → AX + B). Likewise, in double replacement both reactants of the different compounds exchange places, (AB + XY → AX + BY). Finally, a lesser known reaction is an acid-base reaction. Where an acid and a base put together, react and neutralize their properties producing a salt and water, (HCl + NaOH → NaCl +

Chemical reactions occur very often in people’s everyday lives. There are six main types of reaction. These include decomposition reactions, synthesis reactions, single-displacement reactions, double displacement reactions, combustion reactions, and nuclear reactions. Both single and double displacement reactions can be broken down into more specific reactions. Single displacement reactions can be classified as metal displacement, which is cation; and halogen displacement, which is anion. Double displacement reactions will break into three different situations: formation of a gas, formation of a solid (precipitate), and neutralization.
