Is burning coal in a furnace a chemical change?
Yes, burning coal in a furnace is a chemical change. During combustion, the coal undergoes a chemical reaction with oxygen to produce heat, carbon dioxide, and other byproducts, resulting in a change in the chemical composition of the coal.
How hot does coal burn and what factors influence its combustion temperature?
Coal typically burns at temperatures ranging from 1,100 to 2,200 degrees Fahrenheit. The combustion temperature of coal is influenced by factors such as the type of coal, the amount of oxygen available for combustion, the size and shape of the coal particles, and the efficiency of the combustion process.
Is burning coal for a barbecue a physical change?
Yes, burning coal for a barbecue is a chemical change. This is because the combustion process results in a chemical reaction where the coal combines with oxygen to produce heat, carbon dioxide, and other byproducts.
What is the word equation for the combustion of coal?
The word equation for the combustion of coal is: coal + oxygen → carbon dioxide + water vapor.
How could a person change the stored energy in a lump of coal into chemical enegry?
A person could change the stored energy in a lump of coal into chemical energy by burning the coal. Combustion of coal involves a chemical reaction that releases the stored energy in the form of heat and light energy.
What kind of change is the combustion of coal?
Exothermic - Gives of heat.

What is coal combustion?
Coal combustion is the process of burning coal to produce heat energy. This process releases carbon dioxide, sulfur dioxide, and other pollutants into the atmosphere, contributing to air pollution and climate change. It is commonly used in power plants to generate electricity.
What has the author Erich Raask written?
Erich Raask has written: 'Mineral impurities in coal combustion' -- subject(s): Coal, Coal-fired power plants, Combustion, Furnaces, Mineral inclusions
What is the chemical equation of coal combustion?
The combustion of coal can be represented by the general equation: C + O2 → CO2 This equation shows that carbon (C) in coal reacts with oxygen (O2) to produce carbon dioxide (CO2) as the combustion product.
What are the products of combustion for coal and petroleum?
Complete combustion will result in the production of CO2 and H2O.
Why is coal combustion useful?
Coal combustion is useful because it generates electricity and heat, which are essential for industrial processes, residential heating, and power generation. It is a reliable and cost-effective energy source, particularly in countries with abundant coal reserves. However, coal combustion also releases pollutants and greenhouse gases, contributing to environmental and health issues.
