The principal materials used for fuel are petroleum and coal. Ordinary hard coal is called anthracite coal, and the soft, lumpy kind that crumbles very easily is called bituminous coal. All fuels are composed of carbon, or compounds of carbon and hydrogen, called hydrocarbons, combined with such impurities as ash, sulphur, nitrogen, etc.
What else can I help you with?
Is bituminous coal detrital or chemical in nature?
Bituminous coal is a chemical sedimentary rock, formed from the remains of plants that have undergone chemical changes over time.
When coal burn it leave ash behind. Ash so produced is lighter than the coal which has burnt. justify the decrease in mass in the light of law of conservation of mass?
When coal burns, it undergoes a chemical reaction with oxygen to produce heat, light, and various byproducts, including ash. The ash produced is lighter than the original coal because during the combustion process, some of the mass is converted into gases such as carbon dioxide and water vapor that are released into the atmosphere. This decrease in mass is in line with the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction, only rearranged. In this case, the mass of the coal is rearranged into lighter byproducts like gases and ash.
What is another term for chemical change?
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
What tells the story of a chemical reaction?
The balanced chemical equation for a reaction tells the story of a chemical reaction by showing the reactants that are consumed and the products that are formed. It also provides information on the stoichiometry of the reaction, including the ratios of reactants and products involved.
Define chemical reaction and chemical equation?
A chemical reaction is a process that results in the transformation of chemical substances into new substances with different properties. A chemical equation represents this reaction using chemical formulas of the reactants and products, along with their respective coefficients to balance the equation.
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.
When coal burns is it a chemical reaction?
Burning coal is a chemical process in which coal reacts with oxygen and forming carbon doxide and or monoxide.
Is burning coal for heat a chemical change?
Yes, it is an exothermic chemical reaction.
What is the chemical equation for the reaction of coal and carbon dioxide?
CO2,g + Cs --> 2COg is the chemical reaction equation.
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.
Is burning coal an exothermic chemical reaction?
Yes, burning coal is exothermic, in fact, that is why people burn coal. It produces heat.
Is burning coal for a barbecue physical or chemical change?
Burning coal for a barbecue is a chemical change because the coal undergoes a chemical reaction with oxygen in the air to produce heat and light, along with byproducts like carbon dioxide and ash.
The combustion of coal is a change?
The combustion of coal is a chemical change because it involves the chemical reaction of coal with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. This process is irreversible and results in the formation of different substances than those initially present.
Why is burning of coal a chemical change?
Burning coal is a chemical change because it involves a reaction between the coal (a hydrocarbon) and oxygen in the air to produce heat, light, and carbon dioxide. This reaction results in the formation of new substances, indicating a chemical change.
What type of chemical reaction takes place when coal burns?
egg rolls
What you might see when coal is burning to show that a chemical reaction is happening?
Coal changes to ash, flames with heat coming out.
