Why doesn't the complete combustion of ethanol from sugercane contribute to global warming?
Ethanol from sugar cane is a biofuel. Burning biomass or biofuel does not contribute to global warming. When the sugar cane was recently growing it removed carbon dioxide from the air. When the ethanol is burnt, that same carbon dioxide is returned to the air. This is part of the natural carbon cycle.
The carbon dioxide that comes from burning fossil fuels (coal, oil and natural gas) was taken out of the atmosphere millions of years ago, so releasing it now is adding extra CO2 (and causing global warming).
This is why biomass is renewable energy and better than fossil fuels.
What else can I help you with?
What is the balanced equation when ethanol undergoes complete combustion?
Ethanol + Oxygen --Δ--> Carbon dioxide + WaterC2H5OH + 3 O2 --Δ--> 2 CO2 + 3H2O
Does ethanol have a sweet taste in gasoline?
No, ethanol does not have a sweet taste in gasoline. Ethanol is used as a fuel additive, primarily for its combustion properties, and does not contribute a noticeable taste to gasoline.
What is the chemical formula for the combustion of ethanol?
C2H5OH + 3O2 --> 2CO2 + 3H2O Ethanol + Oxygen --> Carbon Dioxide + Water
What happen when we put flame in the ethanol?
When flame is applied to ethanol (C2H5OH), it undergoes combustion, a chemical reaction where it reacts with oxygen (O2) in the air to produce carbon dioxide (CO2), water (H2O), and heat. The balanced chemical equation for the combustion of ethanol is: C2H5OH + 3O2 → 2CO2 + 3H2O In this reaction, the ethanol molecule breaks apart, and its carbon and hydrogen atoms combine with oxygen atoms from the air to form carbon dioxide and water vapor, respectively. This reaction releases a significant amount of heat energy, which is why ethanol is used as a fuel in alcohol burners, stoves, and engines. When you observe a flame applied to ethanol, you will see a blue-colored flame, indicating complete combustion. The heat produced by the combustion of ethanol can be used for various purposes, such as heating, cooking, or powering engines.
Write a balanced symbol equation for the complete combustion of ethanol?
It is: C2H5OH+3O2 ----> 2CO2+3H2O
What is the balanced equation for the complete combustion of ethanol in oxygen?
The complete combustion of ethanol in oxygen proceeds according to the balanced equation C2H6O + 3 O2 -> 2 CO2 + 3 H2O.
What is the balanced equation when ethanol undergoes complete combustion?
Ethanol + Oxygen --Δ--> Carbon dioxide + WaterC2H5OH + 3 O2 --Δ--> 2 CO2 + 3H2O
What is the balanced equation for the complete combustion of ethanol in a stream of air?
This equation is C2H5OH + 3 O2 -> 2 CO2 + 3 H2O.
Does ethanol have a sweet taste in gasoline?
No, ethanol does not have a sweet taste in gasoline. Ethanol is used as a fuel additive, primarily for its combustion properties, and does not contribute a noticeable taste to gasoline.
Complete equation for the combustion of ethanol in air?
C2H5OH + 3O2 → 2CO2 + 3H2Oethanol + oxygen → carbon dioxide + waterThis is the equation for complete combustion of ethanol in air. If there is a lack of oxygen, carbon monoxide (CO) may be formed instead of carbon dioxide (CO2). Further deprivation of oxygen will lead to unburned carbon residue (C), or soot.
Is ethanol combustion exothermic?
Yes, ethanol combustion is an exothermic process. When ethanol reacts with oxygen during combustion, it releases energy in the form of heat and light, making it an exothermic reaction.
Why does ethanol burn differently than ethanol and water mixed?
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
Does water affect the heat of combustion of ethanol?
There are two angles to this question: 1. If your ethanol is contaminated with water it will reduced the amount of useful heat generated since the water will boil off while the ethanol is burning. 2. The water generated as a result of combustion is included as a term in the calculation of heat of combustion.
What is the chemical formula for the combustion of ethanol?
C2H5OH + 3O2 --> 2CO2 + 3H2O Ethanol + Oxygen --> Carbon Dioxide + Water
What reactants produce carbon dioxide?
When an organic molecule such as methane or ethanol undergoes complete combustion (in the presence of oxygen) it produces Carbon dioxide and water.
What is the combustion equation for ethanol burned in oxygen?
Combustion of ethanol with oxygen: C2H5OH + 3 O2 --> 2 CO2 + 3 H2O + 'Heat'
