Heat Of Combustion Using Hydrocarbons As Fuel

Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.

The energy released during combustion reactions goes into the surrounding atmosphere because the energy does not disappear it simply goes into the atmosphere of a surrounding area. For example, during the Cheeto experiment the fire being released is the energy but when the fire is out the rest of that energy is moved onto its surrounding like people and the air. One observation that I made during my experiment was when the mass of Cheeto was too big and when the Cheeto began to burn it released its energy onto the can which heated the water inside and that also created energy because the water releases steam and that goes into the air and the people around it. The fire being released wasn't always as expected because if the Cheeto was too big

In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat.

The most common source of heat for the purpose of firefighting comes from chemical reactions. When something burns, it is the result of a chemical reaction where heat is being released. Pyrolysis is the "decomposition or transformation of a compound caused by heat."(Coleman, et al. 81)

Fuel is usually consistent of octane, ethyl benzene, Trimethylpentane, toluene, and brutane. The reactions of 3.51kg of oxygen to one kilogram of fuel causes the production of 1.42kg pf water and 3.09kg of carbon dioxide. Simply written out, it would form an equation similar to C8H18+O2+CO2+H2O —> CO2+H2O. Dismally, this doesn’t work as a proper equation, as one would find it impossible to balance out. The balanced equation would be closer to C8H18+O2 —> CO2+H2O. Now that one is able to balance the equation, we’ll multiply the carbon dioxide and water by eight and nine respectively. Now there are too many oxygen on the right side of the equation (product). We move to the left side of the equation (reactant) and change the O2 to 25/2O2. Balanced, the equation is C8H18+25/2O2 —> 8CO2+9H2O. In terms of heat through energy, this equation can be converted to [(8 x -393.5) + 9 x -241.8)] - 250.1. What this means is for each time the reactant produces the CO2+H2O mixture, -5270kj of energy are produced.

When we add fourth element that is chemical reaction in above mentioned three elements then this is baptized fire tetrahedron. Fire Triangle Elements Fire Tetrahedron Elements Heat Heat Fuel Fuel Oxygen Oxygen Chain reaction Question # 3 Discuss how the “Fire Tetrahedron” can be used to understand the combustion process. Answer#3: The combustion reaction can be considered by four constituents, the fuel, the oxidizing agent, heat and fourth one is abandoned chemical

An Investigation into the Enthalpies of the Combustion of Alcohols = == == == ==

The aim of this experiment was to test the heat of combustion over a period of time, and the energy required to combust alcohols with different carbon chain levels. It was hypothesised that the higher the carbon chain of the alcohol present, the faster the heat of combustion will occur. Meaning more energy will be released for a higher carbon chain. After calculating the results from the experiment it was found that the hypothesis was partially supported. The reasoning for this is as the alcohol that posses a higher carbon chain, generally increased there reaction rates. However there were a few exceptions to this rule.

Heating Curve is why fire and water balance each other in a fight. There are certain temperatures that water changes based on how much heat energy is applied to it.

Fuel combustion is the process of where fuel is burnt that releases heat and light which is an exothermic reaction meaning it releases heat. The fuel is a hydrocarbon, which reacts with oxygen to release energy however a small amount of heat energy is needed to start fuel combustion. The products to the reaction are carbon dioxide and water.

To learn about standard enthalpies of formation and using this to predict if the reaction is exothermic or

When bonds are formed, energy can be released. We are actually feeling the formation of new bonds when we feel heat from a fire.

Lead (II) chromate is

Chemical reactions that release energy are called exothermic reactions, these reactions are observed by an increase in temperature of the reaction mixture.

In this investigation I will be burning alcohol 's to heat up a can of water. I will be burning four alcohol 's, methanol, ethanol, propanol and butanol. The aim is to find out how much energy is produced when burning these alcohols. Alcohol 's react with oxygen in the air to form water and carbon dioxide.

Any kind of fire goes through a chemical change before it turns into that. Even the ones at campsites experience that until you have nothing else left but ashes.
