What else can I help you with?
Do all fires have flames?
No, not all fires have flames. Fires can exist in different forms, such as smoldering or glowing without visible flames. The presence of flames depends on the type of fuel, oxygen availability, and combustion conditions.
Are all spontaneous processes exothermic?
No, not all spontaneous processes are exothermic. Spontaneous processes can be exothermic (release heat), endothermic (absorb heat), or not involve a change in heat at all. The spontaneity of a process is determined by a combination of factors such as entropy, enthalpy, and temperature.
What is the reaction in a fuel cell spontaneous and non spontaneous?
Spontaneous ...Happens all by itself; typically unpredictableNon-spontaneous...You have to do something to make it happen.
What percentage of oxygen to sustain a fire?
A concentration of oxygen in the air above 16% is sufficient to sustain combustion or a fire. Below 16%, fires will have difficulty burning or may not burn at all.
Does all irreversible reactions are spontaneous?
No, not all irreversible reactions are spontaneous - for example, cooking an egg. Once it's cooked, there's no going back to the raw egg stage. But it takes a lot of heat to get to that stage, so it is not spontaneous. If you find an old egg laid by a hen, it will not have a hardboiled texture!
Does spontaneous combustion mean that you literally catch on fire?
No, it means that the fire can start all by itself.
What does spontaneously combust mean?
Spontaneous combustion refers to the phenomenon where an object ignites and burns without an external heat source. This can occur due to a chemical reaction within the object, typically with materials like oily rags or coal dust. Temperature, ventilation, and combustible materials all play a role in spontaneous combustion.
Do all fires have flames?
No, not all fires have flames. Fires can exist in different forms, such as smoldering or glowing without visible flames. The presence of flames depends on the type of fuel, oxygen availability, and combustion conditions.

Is mulch combustible?
Mulch, compost, and decomposition all generate intense heat and a risk of fire. The larger the pile, the more fuel and insulation is available to feed potential combustion. Larger piles also make it more difficult to extinguish a burning mountain of mulch. Mulch that is piled up more than a few inches deep starts to heat up as it decomposes, which can lead to fires starting via spontaneous combustion.
What is the reaction in a fuel cell spontaneous and non spontaneous?
Spontaneous ...Happens all by itself; typically unpredictableNon-spontaneous...You have to do something to make it happen.
What are the differences between CO and CO2?
CO2 (carbon dioxide) is a naturally occurring process required for plants and animals to live. CO is carbon monoxide and can be the result of oxygen starves combustion, forest fires, and internal combustion engines. Both can be deadly.
Can spontaneous combustion of mineral spirits soaked rags occur?
It can. I heard a terrible story: a group of Boy Scouts decided to do a service project and refinished all the woodwork in the church that sponsored their troop. They used mineral spirits-soaked cloths, and left a pile of them in the church. Spontaneous combustion happened and destroyed the church.
Do all fires produce carbon monoxide?
It depends on how much oxygen there is in the area of where is the fire, If the fire has enough or too much oxygen, there is no carbon monoxide, if there is any lack of oxygen, carbon monoxide is produced.
Which equation represents a spontaneous nuclear decay?
All nuclear decay is spontaneous.
What percentage of oxygen to sustain a fire?
A concentration of oxygen in the air above 16% is sufficient to sustain combustion or a fire. Below 16%, fires will have difficulty burning or may not burn at all.
Where is oxygen used in everyday life?
We use it for breathing; we can't live without it. It is also an essential component of all sorts of fires, including internal combustion engines. It's all around us. we can't not use it.
