What needs to happen for combustion to occur?
We don't have to keep lighting a campfire, it just keep burning. To summarize, for combustion to occur three things must be present: a fuel to be burned, a source of oxygen, and a source of heat. As a result of combustion, exhausts are created and heat is released.
Why is oxygen needed for combustion?
Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.). This process is known as oxidation.
Which gas is used in combustion?
oxygen During the combustion process, oxygen is utilized. As Oxygen is required for the combustion to occur.
Which of the following is not a requirement for combustion to occur a oxygen B fuel C Hydrogen D heat?
Carbon dioxide is not a supporter of combustion(burning). Hence, for combustion to take place, Carbon dioxide is not required.
How does combustion occur?
combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
Is air necessary for combustion?
True, air contains oxygen and oxygen is a supporter of combustion. Air or oxygen which helps in burning is called supporter of combustion and the chemical reaction which takes place with the release of heat and light energy is called combustion.
Is oxygen always needed for combustion?
Most of the fires that we see in everyday life are carbon combustion: campfires, oven flames, candle flames, barbecue grills, forest fires, gas furnaces, gasoline burning in engines, etc. The key to remember is that carbon combustion requires oxygen. As soon as there is no oxygen left, carbon combustion stops.
What is necessary for complete combustion of fuels?
What is necessary for complete combustion of fuels? Explanation: For complete combustion of fuels, it is necessary to supply sufficient amount of air. If air supplied is not sufficient then combustion will be incomplete.
How does a combustion reaction occur?
A combustion reaction occurs when a substance reacts quickly with oxygen (O2). For example, in the Figure below, charcoal is combining with oxygen. Combustion is commonly called burning, and the substance that burns is usually referred to as fuel.
What must be a reactant for a chemical reaction to qualify as combustion?
oxygen gas A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor. Notice that this reaction also qualifies as a combination reaction.
What causes flaming combustion to occur?
What causes flaming combustion to occur? A gaseous fuel mixes with an adequate amount of oxygen and heats to ignition temperature.
What 3 elements make the chain reaction that starts a fire?
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Does combustion need carbon?
The main one is energy, as combustion reactions are carried out to produce energy. The other products are carbon dioxide and water. During combustion, the carbon of the hydrocarbon combines with oxygen to form carbon dioxide. The hydrogen of the hydrocarbon combines with oxygen to form water.
Can combustion occur without oxygen?
A fire cannot burn without oxygen.
What does a combustion reaction form?
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor. Notice that this reaction also qualifies as a combination reaction.
What reactants form a combustion reaction?
The reactants in a combustion reaction are always hydrocarbons and oxygen. Hydrocarbons are the fuel, and oxygen is necessary for combustion.
What three requirements must be satisfied to initiate and sustain combustion?
To initiate and sustain combustion, (1) a fuel must be present, (2) oxygen must be available in sufficient quantity to combine with the fuel, and (3) heat must be applied to initiate the combustion, and sufficient heat must be generated to sustain the reaction.
What are the three elements needed for combustion?
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
What is combustion fire?
Combustion is the reaction between a fuel (such as wood, coal, etc.) and an oxidant, usually oxygen in the air. More simply, it's what happens when a substance is heated and reacts with oxygen to release energy – in the case of fire, that energy is usually in the form of heat, but can also be light and sound.

How does spontaneous combustion happen?
Spontaneous combustion can occur when a substance with a relatively low ignition temperature (hay, straw, peat, etc.) begins to release heat. This may occur in several ways, either by oxidation in the presence of moisture and air, or bacterial fermentation, which generates heat.
What physical state must a fuel be in to produce a flame Why can it produce a flame only in this state?
A fuel will achieve a reaction rate with oxygen sufficient to produce a flame only when it is in the gaseous state. A liquid burns when the temperature is high enough to vaporize it (flash point), while a solid must be hot enough to decompose into gaseous products (pyrolysis).
What are the three needed for combustion to occur what will happen if one of these is not present?
There are three components needed to start a fire: fuel, oxygen, and heat. This is commonly referred to as the fire triangle. If any one of the components is missing, a fire cannot occur.
What are the three elements that must be present for a fire to start and continue burning explain briefly?
The fire triangle, or combustion triangle, is the three components needed to ignite and sustain a fire. The three ingredients of a fire triangle are; heat, fuel and oxygen.
Which is a combustion reaction?
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor: 2H2(g)+O2(g)→2H2O(g)
What happens in a combustion reaction quizlet?
In a combustion reaction, a compound or element reacts with oxygen, releasing a large amount of energy in the form of light and heat. We use combustion reactions every day to release energy in ways that are useful to us (for cooking, for fuel, etc.).
What makes a combustion reaction?
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor. Notice that this reaction also qualifies as a combinationreaction.
What is combustion answer?
Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen. When fuel and oxygen react it releases the heat and light energy. Heat and light energy then result in the flame. So, the formula for Combustion reaction is Hydrobcarbon + Oxygen = Heat energy.
What is heat combustion?
The heat of combustion (energy content) of natural gas is the amount of energy that is obtained from the burning of a volume of natural gas is measured in British thermal units (Btu).
