How do flames produce light and heat?
Flames produce light and heat through the process of combustion. When a substance burns, it releases energy in the form of heat and light. The heat comes from the exothermic reaction of combustion, while the light is produced by incandescent particles in the flame emitting photons as they reach high temperatures.
How are explosions different from other chemical reactions?
Yes, combustion is a chemical reaction, because it is a reaction between a molecule and oxygen (O2) to produce a new molecule plus CO2 (if it's a complete combustion) or CO (if it is an incomplete combustion). Combustion is also an exothermic reaction, which means that heat is released.
What happens when something burns and why does it produce heat and light?
When something burns, it undergoes a chemical reaction called combustion. During combustion, the material combines with oxygen in the air to produce heat and light. The heat is generated because the chemical bonds in the material are broken, releasing energy. The light is produced as a result of the high temperatures reached during the combustion process, causing the material to emit photons.
How do you know why thermal energy by burning matchstick?
When a matchstick is burned, the thermal energy is released as a result of the chemical reaction between the match head (containing sulfur and potassium chlorate) and the striking surface (containing red phosphorus). This reaction generates heat energy, causing the matchstick to ignite and produce a flame.
This is a burning of a substance in the presence of oxygen?
Generally it is said that burning need oxygen. but in some cases oxygen is not involved in burning process especially when organic matter is burned in the limited or zero supply of oxygen to convert it into biochar for soil application. Burning needs any gas not necessarily oxygen. eg hydrogen also help burning process.
A combustion reaction occurs when a substance, usually containing carbon reacts with to produce energy in the form of heat and light?
oxygen
A reaction occurs when a substance reacts with oxygen to produce energy in the form of heat and light?
The reaction you are describing is likely combustion, which is a type of chemical reaction where a substance combines with oxygen to produce heat and light. This process is exothermic, meaning it releases energy in the form of heat and light. Combustion is a common reaction in processes like burning fuels.
A combustion reaction occurs when a substance usually containing reacts with oxygen to produce energy in the form of heat and light.?
oxygen Wrong! its CH4 + 2O2 → CO2 + 2H2O
What type of reaction is a campfire an example of?
A campfire is an example of combustion reaction, where a substance (such as wood) combines with oxygen in the air to produce heat and light.
Do acids react with alkalis in a combustion reaction?
No, acids and alkalis do not react in a combustion reaction. Combustion reactions involve a substance reacting with oxygen to produce heat and light. Acids and alkalis typically do not react in this way.
What chemical reaction where a substance reacts rapidly with oxygen?
One example of a chemical reaction where a substance reacts rapidly with oxygen is combustion. In combustion, a substance, such as a fuel like gasoline or wood, reacts with oxygen in the air to produce heat, light, and various combustion products like carbon dioxide and water vapor.
Explain what is combustion?
Did you mean combustion? Combustion is the chemical reaction between a fuel and an oxidant which will produce heat. Ex: a camp-fire is a combustion, the gas being burned in the engine of your car is also.
Is methane gas reacts with oxygen gas to produce carbon dioxide and water a combustion?
Yes, the reaction of methane gas with oxygen gas to produce carbon dioxide and water is a combustion reaction. Combustion reactions are characterized by the rapid reaction of a substance with oxygen, often producing heat and light as byproducts.
Sulfur burns in oxygen to produce sulfur dioxide type of reaction equals?
S + O2 à SO2 This is a combustion reaction
When an acid and an alkali react it is called combustion?
Actually, when an acid and alkali react, it is called a neutralization reaction. This reaction results in the formation of water and a salt. Combustion involves the reaction of a substance with oxygen to produce heat and light.
Are glow sticks an example of a combustion reaction?
No, a combustion reaction is where a chemical reacts with oxygen to produce an oxide and lots of heat. Glow sticks use a a kind of reaction chemiluminescence. The reactions often involve oxygen particularly hydrogen peroxide, but they are not combustion reactions and typically produce little to no heat
What is a necessary product in a combustion reaction?
A necessary product in a combustion reaction is carbon dioxide (CO₂). During combustion, a fuel (typically containing carbon and hydrogen) reacts with oxygen (O₂) to produce energy, water (H₂O), and carbon dioxide if the combustion is complete. Incomplete combustion can also produce carbon monoxide (CO) and other byproducts, but CO₂ is a key indicator of complete combustion.
