What evidence is there to prove phlogiston theory of burning was correct?
The phlogiston theory has been debunked by the discovery of oxygen. When materials burn, they combine with oxygen, not phlogiston as believed in the theory. The understanding of combustion and oxidation provided by oxygen led to the rejection of the phlogiston theory.
When iron rusts is it a phlogiston theory or a oxygen theory?
It is a process that involves oxygen. The phlogiston theory has been disprooven for a long time.
Was there evidence to prove the phlogiston theory correct?
The phlogiston theory was widely held in the 17th and 18th centuries to explain combustion and oxidation. However, it was eventually disproven with the discovery of oxygen by Lavoisier. This discovery provided a more accurate explanation for the process of combustion.
What do people believe about the phlogiston theory?
The phlogiston theory, which suggested that all combustible materials contained a substance called phlogiston that was released during combustion, was once widely accepted. However, it has since been discredited with the advancement of modern chemistry and the discovery of oxygen's role in combustion. Today, the phlogiston theory is considered a historical scientific misconception.
An early theory of combustion held that everything that burned contained a substance called?
phlogiston, a hypothetical substance believed to be released during combustion. This theory proposed that materials burned because they released their phlogiston. The discovery of oxygen and its role in combustion led to the rejection of the phlogiston theory.
What was the evidence of phlogiston theory?
One piece of evidence for the phlogiston theory was the observation that combustion released a substance called "phlogiston" from burning materials, leaving behind ash. Another piece of evidence was the weight gain of metals when they were heated in air, which was believed to be due to the absorption of phlogiston. However, the theory was eventually disproven with the discovery of oxygen and the understanding of oxidation.
What was Antonie Lavoisier discovery and the year?
Antoine Lavoisier is known for his discovery of the role of oxygen in combustion around 1777. He demonstrated that oxygen is necessary for combustion to occur and debunked the concept of phlogiston theory.
Why did some scientists disagree with the phlogiston theory?
Some scientists disagreed with the phlogiston theory because it could not explain all the observations, such as the weight changes in substances during combustion. Additionally, the discovery of oxygen and its role in combustion provided a more accurate explanation for the phenomena previously attributed to phlogiston.
Who propose the phlogiston theory?
The phlogiston theory was first proposed by Johann Joachim Becher in 1667. This theory is now considered obsolete and was replaced by the oxygen theory.
What are the bad points of the Phlogiston theory?
The Phlogiston theory was unable to explain certain chemical reactions, such as the combination of metals with oxygen. It also lacked experimental support and was eventually replaced by the more accurate oxygen theory of combustion. Additionally, the concept of phlogiston was found to be vague and arbitrary.
How do you use the word oxygen in a sentence?
The word is spelled oxygen. Humans breathe oxygen and release carbon dioxide. Plants use carbon dioxide and release oxygen.
What evidence was there to prove that the phlogiston pheory was correct?
1. I believe that theories can only be disproven, not proven. i.e. You create a theory and then you try to disprove it, if you can't then you can consider that theory to be true (convicing other people may be more difficult however). 2. I think the theory you describe is disproven as and todays equivalent is what we now know as 'oxidation'.
