A chemical theory that has been known for a long time becomes a law?
When a chemical theory is repeatedly tested and proven to be true under a variety of conditions over a significant period of time, it may be elevated to the status of a law. This indicates that the relationship described by the theory is a fundamental and universally accepted principle in chemistry.
What evidence was there to suggesst that the phlogiston theory was correct?
Support for the phlogiston theory came from observing that substances such as wood and charcoal released a substance (phlogiston) when burned, leaving behind ash. This was believed to explain the weight loss during combustion. Additionally, the theory was used to account for the process of rusting in metals.
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.
Was Rutherford's theory correct or incorrect?
It was correct as far as it went (as are all scientific theories), however it predicted the electrons would all practically instantly spiral into the nucleus while the atom emitted an intense flash of x-rays and gamma rays, which obviously does not happen. It took the addition of Heisenberg's Quantum theory to explain why the electrons stay in "fixed" orbitals and allow the prediction of hydrogen's spectral lines. This combined theory was more correct, and with only minor modifications is the modern atomic theory.
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 is tested in an experiment?
A hypothesis is tested by an experiment. A hypothesis is an estimate or guess about an outcome. The experiment proves whether the hypothesis is correct or not correct.
What proves water is H2O?
hydrogen combined with oxygen turn water.. this is chemistry theory that proves
What is the verb for proof?
The verb for proof is prove.Other verbs depending on the tense are proves, proving and proved.Some example sentences are:"I will prove this theory"."This proves he did it"."I am proving you wrong"."The theory was eventually proved".
Why scientific theory might changed?
Some one proves it wrong.
When can a hypothesis be elevated to the status of theory?
When it proves the tests of repeated experiments
When can a hypothesis be elevated to status of a theory?
When it proves the tests of repeated experiments
How many dimensions do atoms have?
[At least] Three. There could be more if string theory or the theory of branes proves to be true.
Can a theory change over time How?
Not really, if the theory proves to be wrong then it is replaced by something better (using the scientific method)..
If a hypothesis is supported by new data gathered over a period of time it may become a what?
If a hypothesis is supported by new data gathered over a period of time, it may become a theory. A theory is a well-supported explanation that has been extensively tested and confirmed through observation and experimentation.
What will a hypothesis become if its is supported by repeated experimentation?
A scientific theory
What do earthquakes tell about the Earth?
It proves the Plate Tectonics theory suggested by Alfred Wegener.
A working theory becomes a paradigm?
A working theory becomes a paradigm when it stands the test of time and is supported by many experiments.
