What element must be present in a combustion reaction?

What element must be present in a combustion reaction?

Oxygen
Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.

What is combustion of an element?

Combustion means burning, usually in oxygen but sometimes with other oxidants such as fluorine. A combustion reaction happens quickly, producing heat, and usually light and fire. Sometimes the reactant has some other elements, like O, S or N in it.

Is always present in a combustion reaction?

Oxygen, O2 , is always present.

What must be present for a combustion reaction to occur quizlet?

A combustion reaction occurs when a fuel source reacts with oxygen (O₂) to form carbon dioxide (CO₂) and water (H₂O).

How does combustion take place?

Combustion starts with the mixing of fuel and oxidant, and sometimes in the presence of additional compounds or catalysts. The fuel/oxidant mixture can be ignited with a heat source; chemical reactions between fuel and oxidant then take place and the heat released from the reactions makes the process self-sustaining.

What reaction takes place during combustion?

Combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Which element is always present in a combustion reaction Brainly?

Acombustion reaction always has oxygen as one reactant.

What are always the products of a combustion reaction quizlet?

Combustion reactions of simple organic molecules always produce carbon dioxide and water.

What is a combustion reaction quizlet?

Combustion reaction. the reaction of a substance with oxygen, producing one or more oxides, heat and light. Hydrocarbon. a compound that is composed only of the elements carbon and hydrogen.

What are the elements of 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.

What type of process is combustion?

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually a liquid.

What do you need to know about the combustion process?

Three things are required in proper combination before ignition and combustion can take place— Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen.

Which is the source of heat in combustion?

Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer.

What kind of reaction is a combustion reaction?

What type of reaction is a combustion reaction? Combustion is another name for burning. It is an example of an exothermic reaction, a reaction that releases energy to the surroundings. This is mostly thermal energy, but light energy and sound energy are also released.

How are retardants used in the combustion process?

They will replace the oxygen around the fuel affecting one side of the fire triangle. They also absorb heat and thus also alter the heat side of the triangle. Retardants will coat the fuel and protect it from the heat even after the water has evaporated. They also inhibit the flaming combustion by chemical action.
