For this experiment, a few scientists are researching the changes in gas pressure and launch velocity needed to send a film canister across the room using the ignition of ethanol. The independent variable would be the different types of flammable sprays. The dependent variable would be how far the explosions are sent across the room. The constant would be way the device is built for every type of spray, and the control would be the film canisters.
A chemical explosion is just one type of chemical reaction. A chemical reaction is when two or more molecules interact and the molecules change (Rader, Chem4Kids).

You need a very quick chemical reaction, a large and quick change or increase in gas pressure, and a container, or a vessel that holds the pressurized gas to the point where it can violently break out of its container. In this experiment, the gas being pressurized is ethanol. The equation C2H6O+3O2→3H20+2CO2+heat states that ethanol combines with the other parts of the equation in order to make enough energy to cause a chemical explosion.
The scientists then went into deeper research about ethanol and how it will react with the other parts of the equation for the chemical explosion. Ethanol (C2H6O), also called ethyl alcohol, is a type of compound chemical. It is commonly found in alcoholic beverages. It is being looked into and researched as an alternative to powering vehicles and other things that run and depend on gasoline because it is a cleaner and more environment friendly energy source.
The scientists have researched chemicals, chemical reactions, and what is needed for a chemical reaction. They have also researched chemical explosions, which will be the main focus of their experiment, and how they relate and rely on chemical reactions in order to work effectively. They have also researched ethanol, what it is, how it can react with other parts of its chemical formula for an explosion, and how it can be used in other areas of

    The experiment was very helpful in learning how the chemicals do react with each other. Some chemicals change colors, some chemicals remain the same color, but bubble or precipitate, while others might no have any apparent physical change at all. All chemicals react differently to each other in different situations, lighting, temperatures and surroundings. Learning about these different chemicals was very intriguing to me and a fun experiment to do as…

    Objectives: 1. To examine a variety of reactions including precipitation, acid-base, gas forming, and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent what occurs in a chemical reaction. For example, the equation HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l) describes an acid-base reaction, a type of exchange reaction in which the driving force is the formation of water. In an exchange reaction, the…

    This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%.…

    This experiment was all about observing a chemical reaction. During the experiment, we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride, Aluminum foil, and Distilled water. Before the Aluminum was added into the Copper Chloride was turquoise. As we added the Aluminum the color changed to green and the water boiled. So we met the purpose of this lab.…

    This aim of this experiment was to determine whether or not a chemical reaction occurred after the mixing of various chemicals. The evolution of a gas, the formation of precipitation, and the change of temperature or color are all indicative of a chemical reaction. It was assumed that a reaction did not take place if the mixture of chemicals exhibited none of these characteristics. Several precipitation, complex-ion formation, redox, and acid-base reactions were performed.…

    Chemical reaction,is the process by which one or more substances are converted into one or more different substances.Old bonds break and new bonds form. The original substances are called reactants. The resulting substances are called products. It is a simple chemical reaction. Another simple reaction might involve a reactant molecule breaking apart. Many enduring substances such as rock and water are highly stable. One molecule of methane and two molecules of oxygen yield one molecule of carbon dioxide. Chemists summarize chemical reactions using formulas called chemical equations. Chemical equations generally show the product formed when the…

    Investigation: The coke and mentos experiment is investigation of the chemical change and understanding the way substances and gases work, the experiment shows the way mentos( a hard candy) reacts with coke(soft drink), and creates a mild explosion . It is basically the process of bubbles that are called nucleation, it is when substances form on their own to make a reaction, carbon dioxide make up the bubbles, nucleation is not very explosive when tested with mentos, the reaction is made because mentos have little openings on the surface that enables the carbon dioxide to seep in to creat a minor explosion. The experiment is used in the real world as it imitates what a situation of carbon dioxide, nucleation and how it would react to substances.…
