What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
Why was the Arrhenius theory of acids and bases modified?
The Arrhenius theory was modified because it was limited in its scope to only aqueous solutions and did not account for reactions in non-aqueous solvents. The Bronsted-Lowry theory extended the concept of acids and bases to include proton transfer reactions in all solvents, leading to a more inclusive and versatile understanding.

What is a scientist hypothesis?
A hypothesis is a temporary explanation for some observation. It is then tested and, if is found to be incorrect, a new one has to be formed. If found to be correct, it becomes a theory. If that theory is later found to have a counter-example it is modified (hypothesis -> theory - same process) or a completely new hypothesis proposed and tested. The hypothesis alwasy comes before the theory. it is a practical explanation that the scientist develops that accounts for a theory.
What is a certifying officers maximum level of precuniary liability with regards to erroneous payments?
A certifying officer's maximum level of pecuniary liability for erroneous payments is typically limited to the amount of the erroneous payment itself. This liability arises when a certifying officer certifies a payment that is later determined to be improper due to a lack of legal entitlement or other errors. However, if the officer is found to be negligent or to have acted with willful misconduct, they may face greater liability. Specific limits can vary based on agency policies and applicable laws.
Who first started the thoery of continetal drift?
Alfred Wegner, but people disbelieved him as he was not a proper geologist and he had no mechanism but evidence was later found which supported his theory.
Did ptolemy use the big bang theory?
No. The Big Bang theory came a lot later.
What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
How would today be different if Nicholas Copernicus was never born?
we just wouldn't have figured out that our universe aws heliocentric until a little later Galileo agreed with Copernicus on his theory so we would have found it out still just a little later
When was the theory of relativity created?
