Which of the emissions occurs when any fuel is burned at a high temperature in the presence of air?
When any fuel is burned at a high temperature in the presence of air, it primarily produces carbon dioxide (CO2) and water vapor (H2O) as emissions. Additionally, nitrogen oxides (NOx) can form due to the reaction between nitrogen in the air and oxygen at elevated temperatures. Incomplete combustion may also lead to the release of carbon monoxide (CO) and particulate matter.

What emission occurs when fuel is burned at a high temperature in the presence of air?
Carbon dioxide (CO2) and nitrogen oxides (NOx) are emitted when fuel is burned at a high temperature in the presence of air. These emissions contribute to global warming and air pollution.
Do oxygen and strontium mix?
Oxygen and strontium can react to form strontium oxide (SrO) when heated to high temperatures. This reaction occurs when strontium is burned in the presence of oxygen.
What chemical compound is formed when magnesium is burned?
When magnesium is burned, it forms magnesium oxide (MgO) as a chemical compound. This reaction occurs in the presence of oxygen, where magnesium combines with oxygen atoms to form magnesium oxide.
What is meant by perfect combustion?
Perfect combustion occurs when a fuel is burned completely in the presence of sufficient oxygen, resulting in the production of carbon dioxide and water as the only byproducts. This ideal process is characterized by maximum heat release and high efficiency.
Why is imcomplete combustion messy?
Incomplete combustion occurs when there is not enough oxygen present to fully burn a fuel, leading to the production of soot, smoke, and harmful pollutants like carbon monoxide. These byproducts can create a messy visual appearance due to the presence of dark particles and residues that are not completely burned. Additionally, incomplete combustion releases harmful emissions that can pose health risks and contribute to air pollution.

What does indirect civil contempt mean?
Direct contempt occurs in the presence of the court. Indirect contempt occurs outside the presence of the court, and Civil contempt often occurs indirectly.
Thermal decomposition and decomposition temperature-is it refer to the same things?
Thermal decomposition is the process by which chemical bonds are broken in the presence of heat. Decomposition temperature is the temperature at which thermal decomposition occurs, which differs for different compounds.
Is the chemical change that occurs when flues are burned is called oxidation?
Yes, it is.
Which of these is not a factor influencing the rate of a chemical reaction?
The color of the reactants is not a factor influencing the rate of a chemical reaction. Factors that do influence reaction rate include temperature, concentration of reactants, presence of a catalyst, and surface area of reactants.
Cellular respiration occurs in the presence of?
Oxygen. O2.
Cellular repiration occurs only in the presence of?
Oxygen
What combines with oxygen to form sulfur dioxide?
S8 + 8 O2 ---> 8 SO2 ^ ^ ^ small numbers
