What chemical reaction takes place when you put a burning paper in a closed jar?
When you put a burning paper in a closed jar, the paper will consume oxygen inside the jar as it burns. Eventually, the fire will extinguish once the oxygen is depleted. The reaction is primarily combustion of the paper with oxygen to produce carbon dioxide and water vapor.
What 2 processes put carbon back into your atmosphere?
The two main processes that put carbon back into the atmosphere are the respiration of living organisms, including plants and animals, and the combustion of fossil fuels. Respiration releases carbon dioxide as a byproduct, while the burning of fossil fuels, such as coal, oil, and natural gas, releases carbon dioxide that has been stored underground for millions of years. Both processes contribute to the accumulation of carbon dioxide in the atmosphere, leading to climate change.
Why does the combustion of biomass release no net carbon into the atmosphere?
Biomass is vegetable matter, like unwanted parts of sugar cane (bagasse), as well as residue from tree felling and other things. When vegetation grows, it removes carbon dioxide (CO2) from the atmosphere. When the same material is burnt as biomass, that same CO2 is put back into the carbon cycle.
What is the word equation for the process that releases energy in cells?
The word equation for the process that releases energy in cells is cellular respiration. This process converts glucose and oxygen into carbon dioxide, water, and ATP (adenosine triphosphate), which is the cell's energy currency.
What happens when you put carbon in water?
When carbon is put in water, it can react to form carbonic acid. This process is slow, so typically carbon will just remain suspended in water without any immediate reaction.
Can carbon dioxide put flames out?
No, carbon dioxide does not put flames out. It is non-flammable and does not support combustion. When carbon dioxide is released onto a fire, it can displace oxygen, which in turn can smother the fire by removing one of the elements needed for combustion.
What is the equation for the combustion of methane gas?
The balanced chemical equation for the combustion of methane gas (CH4) is: CH4 + 2O2 → CO2 + 2H2O where methane reacts with oxygen to produce carbon dioxide and water.
How much carbon is put into the atmosphere each year by fossil fuel combustion?
Approximately 37.1 billion metric tons of CO2 are released into the atmosphere each year from fossil fuel combustion, accounting for the majority of anthropogenic carbon emissions.
What happens when a lighted splint is put near carbon Dioxide?
When a lighted splint is put near carbon dioxide, it will be extinguished because carbon dioxide does not support combustion. This is because carbon dioxide does not contain any free oxygen atoms needed for combustion to occur.
What is the balance equation for a complete combustion when the fuel used consist only of carbon and hydrogen?
Methane: CH4+2O2->CO2+2H2OEthane: C2H6+3.5O2->2CO2+3H2OEthene: C2H4+6O2->2CO2+2H2ODo note decimals are allowed in the equation. However, it is best to put into whole numbers (for equation of ethane, multiply all the numbers by 2 except those in compounds/elements).
What does the word domain mean in math?
Domain is the independent variable in an equation. It is what you put "in" the equation to get the Range.
Why does a car put out carbon dioxide?
The combustion involved in burning of gasoline creates a few products. One being water vapor, the other being Carbon Dioxide [CO].
How do cars put carbon dioxide into the air?
The internal combustion engine ignites the fuel. That fuel then expands as it burns into carbon dioxide. Carbo ndioxide is what is left from the burning of fossil fuels.
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.
Does fire need carbon dioxide to burn?
No, fire requires oxygen to burn, not carbon dioxide. Carbon dioxide is a byproduct of combustion when a material burns in the presence of oxygen.
How does carbon dioxide gets in the air?
From the cars imitting gas into the air creates an atmosphere like a greenhouse. Also, when trees die, the carbon dioxide they have collected gets put into the air.
Why exhaling carbon dioxide can not put out a fire?
Exhaling carbon dioxide from the body is not enough to put out a fire because the concentration of CO2 in exhaled air is relatively low (around 4-5%). In order to effectively extinguish a fire, a higher concentration of carbon dioxide (around 12-15%) is needed to displace the oxygen and suppress combustion.
