Is Magnesium burns brightly when ignited physical or chemical property?
The combustion of magnesium in air is a chemical reaction.
What material burns cold?
There is no material that burns cold. Burning is a chemical reaction that releases heat energy.
When gas burns you can tell it is a chemical reaction because?
you saw a reaction you smelt something you heard something and you cant get that gas back to its original form
What kind of chemical reaction is combustion of coal in air?
The combustion of coal in air is an exothermic redox reaction. During this process, carbon in the coal reacts with oxygen in the air to produce carbon dioxide and heat, releasing energy. Additionally, impurities in coal can lead to the formation of other products, such as sulfur dioxide if sulfur is present. Overall, it is a crucial reaction for energy production but also contributes to environmental pollution.
When hydrogen burns in air the change is chemical Give two reasons to support this assertion?
When hydrogen burns in air with H2+O2= H20
What type of chemical reaction takes place when coal burns?
egg rolls
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
Is burning coal an example of a physical reaction or a chemical reaction?
Chemical. It is called combustion.
What type of chemical reaction happens when wax burns?
This is an oxydation reaction.
What evidence shows that a chemical reaction has taken place when you burn coal?
Evidence that a chemical reaction has taken place when burning coal includes the release of heat and light, the production of carbon dioxide and other combustion byproducts, and the change in the physical properties of the coal, such as the formation of ash.
Is burnig a useful chemical reaction?
Burning is a VERY useful chemical reaction. Automobile engines depend of burning- as does the furnace that heats your home, and the oven that bakes your bread, or the power plant that burns oil, coal or natural gas to make electricity.
What energy transfers happen when coal is turned in to electric?
when coal burns the energy change is chemical -------------> electrical
Is burning coal for heat a chemical change?
Yes, it is an exothermic chemical reaction.
What happens when coal burns?
When coal burns, it releases heat energy and produces carbon dioxide, water vapor, and other byproducts. The combustion process breaks down the carbon content in coal, releasing heat and energy that can be used for various purposes such as electricity generation or heating. However, burning coal also releases pollutants and greenhouse gases, which contribute to air pollution and climate change.
is burning coal also exothermic?
Yes, burning coal is considered an exothermic reaction, meaning it releases heat energy during the combustion process where carbon in coal reacts with oxygen to produce carbon dioxide. Explanation: Definition of exothermic: A chemical reaction that releases heat energy to the surroundings is called exothermic. Coal combustion: When coal (primarily carbon) burns, it combines with oxygen from the air, forming carbon dioxide and releasing heat as a byproduct. Key points about burning coal: Chemical reaction: C (solid) + O2 (gas) -> CO2 (gas) + heat Heat release: The energy released during this reaction is what makes burning coal an exothermic process.
What is the chemical equation for the reaction of coal and carbon dioxide?
CO2,g + Cs --> 2COg is the chemical reaction equation.
Chemical reaction between man and flame?
Burns. Very severe burns. It's easy if you think about it.
