What is carbon char?
Carbon char is the remaining residue following the incomplete combustion of a hydrocarbon. This occurs in some polymers with a char-forming tendancy such as cellulose (containing oxygen) or polycarbonate (containing a cyclic group in the polymer backbone). The better known example of char is of course charcoal.
A solid product of a reaction is known as?
If a reaction that produces a solid product occurs in a fluid phase, the product may be called a "precipitate."
What is a product of weathering and erosion rocks?
Deposition occurs when rocks are weathered then eroded.
What is incomplete combustion?
Reaction or process that does not convert all of the fuel's carbon and hydrogen into carbon dioxide and water, respectively. For example, incomplete combustion of carbon produces carbon monoxide.It is also a flame, but this flame is a jellow one so is not as harmfullHowever none of these answers will help with your homework when you are in year 7.
What happens when there is an incomplete combustion?
Incomplete combustion occurs when there is only a limited amount of oxygen. This means that CO and C (soot) is produced as well as just CO2 (carbon dioxide). -C is a lung irritant ie. can trigger asthma -CO displaces haemoglobin from blood. ie. CO takes oxygen OUT OF the blood supply so that it can become CO2. Therefore, cells do not get enough oxygen. -CO can cause breathing difficulties, headaches, fatigue, unconsciousness, and even death -CO is a colourless, odourless toxic gas (so it cannot be sensed until it's too late) -C (soot) can block sunlight getting to plants therefore they cannot photosynthesise and produce oxygen
When hydrocarbon undergoes combustion what does it reacts with?
It reacts with oxygen to produce carbon dioxide, water, and heat.
Fuel rich fire that occurs when the supply of air or oxygen is limited?
incomplete combustion
What is a by product of combustion?
If the combustion is incomplete, carbon monoxide can be formed. Other than that, if you are in an enclosed space, carbon dioxide could be dangerous. Also, if a fire occurs, that could also be dangerous.
Why does the flame in a gas cooker go out when you turn of the gas?
For combustion to occur, a fuel source and an oxidant must be present. For example: methane (CH4) CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) Combustion usually occurs when a hydrocarbon reacts with water to produce carbon dioxide and water.
What would be the product when combustion reaction occurs in a small tightly-closed container?
Carbon monoxide (and some carbon dioxide) as the oxygen supply is restricted.
What energy given off by burning matchstick?
The energy given off by burning a matchstick is mainly in the form of heat and light. The heat is a result of the exothermic combustion reaction that occurs when the matchstick is ignited, and the light is emitted as a by-product of the combustion process.
Is the combustion of methane endo or exothermic reaction?
Let's think about what happens in the combustion of methane. Take natural gas for example (methane) used to heat homes, or used in stoves. The product is heat, therefore heat is given off. Therefore EXOTHERMIC.
What is carbon char?
Carbon char is the remaining residue following the incomplete combustion of a hydrocarbon. This occurs in some polymers with a char-forming tendancy such as cellulose (containing oxygen) or polycarbonate (containing a cyclic group in the polymer backbone). The better known example of char is of course charcoal.
Why does combustion occur?
The combustible compounds are unstable so to gain the stability as CO2 and H2O they catch the fire and combustion occurs.
How are the incomplete and complete combustion reactions different?
In complete combustion, all the reactants will be converted into carbon dioxide and water. In incomplete combustion, some of the reactants will be converted to carbon dioxide, some will become carbon monoxide, and some may not react at all. Quite often incomplete combustion will result in a "sooty" flame.
What occurs in the combustion chamber of a four stroke engine?
Apex Exhaust
A reaction occurs when a substance reacts with oxygen to produce energy in the form of heat and light?
This is an oxidation reaction (combustion, burning).
