An organic peroxide is any organic carbon-containing compound having two oxygen atoms joined together -O-O.
Devise a suitable method for investigating the effect of a given variable on the speed of a reaction. For the experiment above, time was the variable that we changed.
An explosive is a material, either a pure single substance or a mixture of substances, which is capable of producing an explosion by its own energy  . It is not proper to define an explosive as a substance, or a mixture of substances, which is capable of undergoing a . Aug 30, ·) describe combustion in terms of slow, spontaneous and explosive reactions and explain the conditions under w? Is the combustion of glucose an example of slow, spontaneous or explosive reaction? Spontaneous combustion reaction examples?Status: Resolved. The speed of the reaction is what distinguishes an explosive reaction from an ordinary combustion reaction. However, coal dust is hazardous to workers if it is suspended in air outside the controlled environment of grinding and combustion equipment.
The experiment could also be designed around other variables: Interpret data obtained from experiments concerned with speed of reaction. Once you have carried out the experiment and obtained data, you'll be able to come to a conclusion on what you were investigating.
Describe the application of the above factors to the danger of explosive combustion with fine powders e. So you know that variables affecting the rate of a reaction are temperature, concentration, and surface area.
These are applicable to real life situations. In a flour mill, flour is produced.
|Combustion of hydrogen in air||Explain the relationship between ignition temperature and activation energy Some fuels are easier to set fire to than others.|
|Lesson Plan: Oxidation Reactions (Redox) Using a Film Clip from Daylight||Lambert Reproduction or excerpts permitted if request is made to entropy. It is the ultimate basis of chemical industries that have kept the world from starvation for the past half century fertilizer manufacture using nitrogen from the air and kept us healthy and less in pain in that time via processes for life-saving and pain-relieving pharmaceuticals.|
Flour particles are very small, so they have a large surface area. If there is a lot of flour in the air, a small spark can cause an explosion between flour and oxygen. In a coal mine, the air is filled with flammable gases.
If the gases reach a certain concentration they can form an explosion with air. Describe and explain the effects of temperature and concentration in terms of collisions between reacting particles concept of activation energy will not be examined.
As mentioned above, a higher temperature will give particles more energy to move and collide, and a higher concentration means there are more particles in the space that will collide. As a reaction occurs and the reactants get used up, the concentration of the substance decreases; this is why reactions slow down as they happen over a span of time.
Define catalyst as an agent which increases rate but which remains unchanged. A catalyst is a substance thats speeds up a reaction, but the catalyst itself will not be used up.Lecture The Arrhenius Equation and reaction mechanisms.
Recall that for me to initiate the spontaneous ethanol combustion reaction, I had to raise the temperature of the system by lighting a match.
The reason for this follows from transition state You should be able to describe . The other shows an example of spontaneous combustion of a large pile of hay. Helpful Background: Explosions, like the one shown in Daylight and many other movies, are nothing more than oxidation-reduction reactions which happen very rapidly.
Spontaneous combustion has long been recognized as a fire hazard in stored coal.
Spontaneous combustion fires usually begin as "hot spots" deep within the reserve of coal. The hot spots appear when coal absorbs oxygen from the air. Industrial oxidation processes usually take place at elevated conditions (up to °C and 50 bar), and the contact of hydrocarbons with oxygen can lead to spontaneous combustion hazards, such as explosions, with potential catastrophic consequences.
1 In an engine exhaust line, secondary air injection might be a strategy to reduce pollutant emission. In any case, both functions are present in every explosive (a general term for all three kinds of applications), and the oxygen of the atmosphere plays no role as an oxidizer, as it does in combustion or respiration, two other chemical sources of energy.
What the term means is that the energy released in the reaction of one molecule (or set of molecules) is more than enough to "unfreeze" another molecule so that it can and will react. We call this the chemical "activation energy", you can learn more about it here.
