What is the substance left after a flame test?
The substance left after a flame test is typically a residue of the material that was burned. This residue can vary depending on the original substance and may contain remnants of unburned material, ash, or other byproducts of combustion.
What is a calorific value?
Higher Calorific ValueIs The maximum amount of energy that can be obtained from the combustion of a fuel, including the energy released when the steam produced during combustion is condensed. also known as the "Hhgher heating value"See http://en.wikipedia.org/wiki/Higher_Heating_Value
What is non combustion?
The meaning of noncombustion is "material unable to be burned".
What are cinders made from?
A cinder is a burned or partly burned substance such as coal that is not reduced to ashes but is incapable of further combustion.
How do you write equations of combustion?
Combustion reactions always have O2 as a reactant. The other reactant is the thing being burned. If the thing being burned is a hydrocarbon, the products will be water and carbon dioxide.
How can one determine the heat of combustion for a given substance?
To determine the heat of combustion for a substance, one can conduct a calorimetry experiment where the substance is burned in a controlled environment and the heat released is measured. This heat release is then used to calculate the heat of combustion for the substance.
What does cinders mean?
# A burned or partly burned substance, such as coal, that is not reduced to ashes but is incapable of further combustion. # A partly charred substance that can burn further but without flame.
Is burning of magnesium combustion or combination?
Burning of magnesium is a chemical reaction known as combustion. Combustion is a process in which a substance reacts rapidly with oxygen, producing heat and light. Magnesium, when burned, reacts with oxygen to form magnesium oxide.
How to calculate the enthalpy of combustion for a given substance?
To calculate the enthalpy of combustion for a substance, you need to determine the amount of heat released when one mole of the substance is completely burned in oxygen. This can be done by subtracting the sum of the enthalpies of formation of the products from the sum of the enthalpies of formation of the reactants. The enthalpy of combustion is typically expressed in kilojoules per mole.
What two substance are formed when methane is burned in plenty of oxygen?
When methane is burned in oxygen, assuming complete combustion, the products are carbon dioxide and water.
Is cinder a verb or a noun?
The word cinder is a noun, a singular, common, concrete noun; a word for a burned or partly burned substance that is not reduced to ashes but is incapable of further combustion; a word for a thing,
What is the substance left after a flame test?
The substance left after a flame test is typically a residue of the material that was burned. This residue can vary depending on the original substance and may contain remnants of unburned material, ash, or other byproducts of combustion.
What is bomb caloriemeter?
A bomb calorimeter is a device used to measure the heat of combustion of a substance. It consists of a sealed container (the bomb) where the substance is burned, surrounded by a known amount of water. The heat released during combustion raises the temperature of the water, allowing the calculation of the heat of combustion of the substance.
Stahl thought that all materials which burned contained?
phlogiston
What is good combustion?
Where all the fuel is burned.
What is the process by which engine fuel is burned?
combustion
What is mean by phlogiston?
Phlogiston was a theoretical substance that was once believed to be responsible for combustion. It was thought to be released during burning, explaining why objects burned and became lighter. However, the concept of phlogiston has been discredited, and combustion is now understood as a chemical reaction involving oxygen.
