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.
Who rejected phlogiston theory?
Antoine Lavoisier is credited with rejecting the phlogiston theory. Through his experiments and observations, he was able to show that combustion involved a process of oxidation rather than the release of phlogiston. This led to the development of modern chemistry.
Did chemists believe in the phlogiston theory?
Yes, chemists believed in the phlogiston theory in the 17th and 18th centuries. It was thought that when substances burned, they released a substance called phlogiston. However, the theory was eventually disproven with the development of modern chemistry.
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.
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 is the mixture of calx and phlogiston?
lead calx + phlogiston = metallic lead
What did scientist think phlogiston was?
Phlogiston can be defined as "a hypothetical substance once believed to be present in all combustible materials and to be released during burning." Chemistry was so underdeveloped at the time Antoine Lavoisier gained interest in it that it could hardly be called a science. The prevailing view of combustion was the Phlogiston Theory which involved a weightless or nearly weightless substance known as phlogiston. Metals and fire were considered to be rich in phlogiston and earth was considered phlogiston poor. The following were the main theories put forward for 'phlogiston': * Weight loss when combustibles are burned because they lose phlogiston * Fire burns out in an enclosed space because it saturates the air with phlogiston * Charcoal leaves very little residue when burned because it is made mostly of phlogiston * Animals die in an airtight space because the air becomes saturated with phlogiston * Some metal calxes turn to metals when heated with charcoal because the phlogiston from the charcoal restores the phlogiston in the metal

Was the phlogiston theory of burning correct?
No, it was not. The phenomena explained by the theory are now known to be a result of oxidation, and phlogiston does not exist.
Why did the phlogiston theory change peoples ideas about burning?
because it changed their mind to belive that phlogiston is in flammable things.
What are the good points of the phlogiston theory?
a combustible material is made up of 2 parts: the calx and phlogiston when a substance burnt the phlogiston into air and calx(ash) left behind so there are no good points of this theory
Why phlogiston is an element?
Phlogiston is a hypothetical substance which at one time was thought to be the basis of combustion, but which is now known to be fictitious. It is not an element.
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.

How did Antoine lavoisier disprove the phlogiston theory?
Antoine Lavoisier disproved the phlogiston theory by experimenting with combustion reactions and showing that burning substances gained weight instead of losing it. He demonstrated that oxygen is an essential component of combustion, not phlogiston as proposed by the theory. Lavoisier's precise measurements and meticulous approach to experimental evidence played a crucial role in discrediting the phlogiston theory and establishing the foundation for modern chemistry.
