When wood is combusted it gives of carbon dioxide, water and some other products. Wood is a reactant and after being combusted it is changed into other products so matter is conserved it just changes from one form to another. Law of conservation of matter is important for many processes.
What else can I help you with?
Is the mass of wood and oxygen that allow it to burn equal the mass of ashes and the gas given off during the burning?
Yes. According to the law of conservation of mass, the mass of all the reactants must be equal to the mass of all of the products.
What is a log's mass is 5 kg after burning the of the ash is 1kg explain what may have happened to the other 4 kg of mass?
The missing 4 kg of mass likely turned into gases and escaped into the atmosphere during the burning process. The burning of wood releases carbon dioxide, water vapor, and other byproducts into the air, reducing the mass of the log.
Does burning wood contradict the law of conservation of mass?
By fire and flame it at the same time.
How can you tell that burning wood is an irreversible change?
Burning wood is an irreversible change because it results in the formation of new substances like ash and smoke that cannot be easily reversed back into wood. The chemical structure of the wood is altered during the burning process, making it impossible to return it to its original form.
Burning wood a physical or chemical?
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Is the mass of wood and oxygen that allow it to burn equal the mass of ashes and the gas given off during the burning?
Yes. According to the law of conservation of mass, the mass of all the reactants must be equal to the mass of all of the products.
Does burning wood violate the law of conservation of energy?
No, nothing can violate the law of conservation of energy, it's a law! Energy can convert to mass, and mass can convert to energy, but the overall total of mass and energy in the universe is constant.
Why would a piece of wood loss mass when burn?
It would loose mass as it is being consumed by burning.
How is mass is conserved?
Mass can never be created nor destroyed, so it is "conserved." Even when mass seems to disappear, it never really does; for example, when you burn wood, it turns into ash and gasses like carbon dioxide -- all the atoms of the wood still exist, they've just been rearranged into new states.
Do wood and oxygen combine during burning?
Yes
Why burning wood smell like burning hair?
When wood burns, it produces compounds that are also found in burning hair, such as benzene and toluene. These compounds are released during the combustion process and contribute to the similar smell of burning wood and burning hair.
What is a log's mass is 5 kg after burning the of the ash is 1kg explain what may have happened to the other 4 kg of mass?
The missing 4 kg of mass likely turned into gases and escaped into the atmosphere during the burning process. The burning of wood releases carbon dioxide, water vapor, and other byproducts into the air, reducing the mass of the log.
Why is wood burning an example of chemical energy?
During burning (oxidation) the heat of combustion is released.
What type of energy is use when burning wood?
Burning wood releases chemical energy stored in the wood as potential energy during photosynthesis. This chemical energy is converted into thermal energy and light energy during combustion.
Does burning wood contradict the law of conservation of mass?
By fire and flame it at the same time.
When coal burns it leaves 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.?
During combustion carbon dioxide and water are released; ash is only the residue.
What energy is from burning wood?
Burning wood produces heat energy and light energy. The chemical energy stored in the wood is converted to thermal energy and radiant energy during the combustion process.
