The heat of combustion for paper, which primarily consists of cellulose, is approximately 15-18 MJ/kg (megajoules per kilogram). This value can vary depending on the specific type of paper and its moisture content. When paper combusts, it releases energy through a chemical reaction with oxygen, producing carbon dioxide and water as byproducts. This property is significant in assessing the energy potential of paper waste in recycling and energy recovery processes.
What else can I help you with?
Is the burning of paper a spontaneous reaction?
No, the burning of paper is not a spontaneous reaction as it requires an external heat source to initiate the combustion process. Once the paper is exposed to sufficient heat, it undergoes a chemical reaction with oxygen in the air to produce heat and light energy, resulting in the flame and smoke that we observe during combustion.
What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
What do you call the heat released when 1 mole of a substance undergoes complete combustion?
You think probable to molar heat, expressed in J/mol.
What gas is needed for paper to burn?
Answer:Burning of wood is a process of combustion. By definition if something is undergoing combustion oxygen must be involved in the reaction.
Why do you think the paper must be heated to start burning?
Paper needs to be heated to start burning because combustion requires a certain temperature, known as the ignition point, to initiate the chemical reaction between the paper and oxygen. The heat breaks down the cellulose fibers in the paper, releasing volatile gases that can ignite. Without sufficient heat, these gases do not reach the necessary temperature for combustion, preventing the paper from catching fire. Thus, heating provides the energy needed to overcome this activation barrier.
Is the burning of paper a spontaneous reaction?
No, the burning of paper is not a spontaneous reaction as it requires an external heat source to initiate the combustion process. Once the paper is exposed to sufficient heat, it undergoes a chemical reaction with oxygen in the air to produce heat and light energy, resulting in the flame and smoke that we observe during combustion.
What are two main forms of energy given off when paper burns?
heat and light and it comes from the reaction of the paper material and its combustion in the air.
What are the two main forms of energy given off when paper burns and where does the energy comes from?
heat and light and it comes from the reaction of the paper material and its combustion in the air.

What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
What class extinguisher puts out a paper fire?
It extinguishes a paper fire by cooling...water is a cooling agent...fire is a product of heat...cool the heat=fire goes out.
What do you call the heat released when 1 mole of a substance undergoes complete combustion?
You think probable to molar heat, expressed in J/mol.
Which form of energy is produced when paper is burned?
The form of energy produced when paper is burned is thermal energy, due to the heat released during combustion.
When paper burns in a fire what is a reactant?
The reactant in this case is paper, which undergoes combustion when exposed to heat and oxygen in the fire. The paper combines with oxygen in the air and releases energy in the form of heat and light during the burning process.
Why must paper be heated to start burning?
Paper must be heated to start burning because heat is required to break down the cellulose fibers in the paper and initiate the chemical reaction of combustion. This process releases energy in the form of heat and light, causing the paper to continue burning once it has started.
What is the difference between the heat of reaction and the heat of combustion?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction, while the heat of combustion specifically refers to the heat released during the combustion of a substance with oxygen.
How do you calculate the heat of combustion for a given substance?
To calculate the heat of combustion for a substance, you can use the formula: Heat of combustion (mass of substance) x (heat capacity) x (change in temperature). This formula helps determine the amount of heat released when a substance undergoes complete combustion.
