For combustion to occur, three elements must be present: fuel, oxygen, and heat. Fuel provides the energy source for combustion, oxygen is required to sustain the chemical reaction, and heat is needed to initiate the combustion process. Without any of these elements, combustion cannot take place.

What gas must be present for a combustion reaction to occur?
Oxygen gas must be present for a combustion reaction to occur.
What are 3 requirements to sustain combustion?
Three requirements to sustain combustion are fuel (such as wood or gas), oxygen (from the air), and heat (a ignition source to initiate the reaction). These elements must be present in the right proportions for combustion to occur and be maintained.
What element must be present in order for something to burn?
Oxygen (O2) is required for combustion.
What is always present for a combustion reaction to occur?
For a combustion reaction to occur, three things are required: fuel (such as gas or wood), oxygen (usually from the air), and a source of heat (spark or flame) to initiate the reaction. Without any of these three components, combustion cannot take place.
Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
Why is it so important for the ignition process to occur in a gasoline car?
For a combustion engine to work, it must have the following: Air Fuel Ignition if any of the above are not present, combustion cannot take place.
What reactant must be present to support combustion?
Oxygen.
What must be present for to erosion to occur?
a transporting agent, such as water must be present
What must be present for metamorphism to occur?
The changes to the rock must occur in solid form.
What are 3 requirements to sustain combustion?

What element must be present in order for something to burn?
Oxygen (O2) is required for combustion.
What type of condition must be for minerals fossilization to occur?
what type of conditionals must be present for mineral fossilization to occur
What is the combustion triangle?
The combustion triangle is a concept that represents the three elements necessary for a fire to occur: fuel, heat, and oxygen. These elements must be present in the right proportions for combustion to take place. If one of these elements is removed or changed, the fire will extinguish.
What is always present for a combustion reaction to occur?
For a combustion reaction to occur, three things are required: fuel (such as gas or wood), oxygen (usually from the air), and a source of heat (spark or flame) to initiate the reaction. Without any of these three components, combustion cannot take place.
What martial must be present for cellular respiration to occur?
glucose
What and what must be present for a fire to occur?
fuel, oxygen, and heat
What must be present for fatigue crackling to occur?
Fatigue crackling occurs in materials when repeated cyclic loading, such as stress or strain, is applied. This leads to the growth of micro-cracks in the material that eventually coalesce and result in larger cracks. Proper stress levels and a sufficient number of load cycles are required for fatigue crackling to occur.
