                                                                                  Reactions Complete Versus Incomplete Combustion  So there is something we call a complete combustion and the other a dirty combustion. Fuel such as petrol or methane, etc can undergo complete or incomplete combustion. When methane completes a complete combustion it produces carbon dioxide and water. When methane goes through an incomplete under a limited amount of air it produces carbon monoxide and water or carbon or water. What is Combustion? There are many types of combustion. But I believe the most known one is the combustion with methane which is the one I put above.  Combustion can also be called burning. Combustion is an exothermic reaction which means it gives out heat. Re...

Reactants: CH 4 + 2O 2                                         Hydrocarbon + Oxygen Products: CO 2 + 2H 2 O                         Carbon dioxide + water Combustion reactions also more commonly known as burning, is a reaction when hydrocarbons react with oxygen to produce carbon dioxide and water. This reaction requires starting energy such as a spark or a flame to get it going. Combustion is an exothermic reaction which means that it releases heat in the process of reacting. Combustion can be categorized as either complete combustion or either incomplete combustion. Complete combustion is when all of the reactants react and there is no more reacta...

Combustion Reactions By: Areta  8/2/19 We have heard this term relatively many times, but not in a scientific way. You may have heard combusting . This is an action as you breathe rapidly or the action of when something exploded. But the combustion that will be discussed is the burning reaction people see as an element interacts with oxygen. What is a combustion reaction: A combustion reaction happens when a hydrocarbon reacts with oxygen and creates water and carbon dioxide. Combustions reaction only works with elements that a flammable or in better words combustible. We won't be able to combust a banana or a piece of cloth, or magnesium for example. The elements needed need to be an oxidizer enable to form oxidized products. Combustion reactions are exothermic reactions meaning that they release heat, though some reactions don" t produce heat. In order to know if the reaction is a combustion reaction or not, heat, carbon dioxide, oxygen, and water ...

c 23/Jan/2019 How to make Potato Plastic! Can u imagine that usually plastics take hundreds of years to decompose, and are extremely harmful to the environment. Imagine being in the nice summer sun, at the beach with your friends. Well let me give you a reality check that beach is basically a trash soup, and more than 90% of that soup is made out of plastics. Not only is it harming the water but the animals too. Now we might be thinking well we don’t live in the water so ‘who cares’ right? Well plastics can affect the land also. Well there is a way for us to change this! Make a better world for both the fishes and us. Imagine a plastic that isn’t made out of foreign oil. A plastic that doesn’t use seven barrels of petroleum to produce. Well I got you covered! We can make an eco-friendly plastic made out of POTATOES! Yes you read it right! I said potatoes. This plastic is biodegradable, meaning that it will decompose into nutrients in the soil in about two months and then it will end...

Plastics By: Areta To start of plastic is a “synthetic organic polymer” ( Anne Marie Helmenstine, ThoughtCo.) Meaning their chemical composition is made up of carbon and hydrogen. Plastics are made out of polymers, though polymers have a chemical structure of that include carbon and hydrogen, there are able to add other molecule structures to make different types of plastics. Polymers are unsaturated, meaning during fabrication other bonds can be added and break the double bond, making it complete. These added molecules, structures, can be known for colorants, stabilizers, fillers, and reinforcements. These additives can affect the physical structure, chemical, and usage as well as cost. Examples of different plastics, their chemical formulas, and their use include; High-density polyethylene—HDPE: (HDPE was first produced in England and became famous in the 1950s in the united states. It makes a by a chain of ethylene molecules. The properties of HDPE include: i...

For my lab, I will be testing the melting points of different plastics. My Independent Variable will be the different plastics My Dependent Variable will be the melting point of different plastics My Control Variable will be the amount of plastic I will be putting into the oven to melt. To determine the melting point, I have to be observing the plastic for the whole time while it is being heated. I have to be observing very closely because, to determine the melting point I have to see when the plastic starts to melt and when it is completely melted (1). I will be using two plastics two compare each other, I will use Polyethylene terephthalate which is the most produced plastic in the world and Polyethylene, these two plastics are the most common plastics (2). I will be comparing the melting point of each of the plastics and finding out what plastic is more resistant to heat. Polyethylene terephthalate is thermoplastic which means that it reacts to heat in a ...
