Dalton theorized that an atom was a tiny solid sphere. Today we know that atoms are not solid, in fact are mostly open space.
The molar mass of a substance in daltons is the mass of one mole of that substance, measured in daltons.
The Norse believed it was, and no one has been able to have disproved or proved it thus far.
A scientific theory can never be "proven". It can only be "Disproved. Science is a process of elimination. We eliminate those theories which are not in agreement with current experimental evidence. But, it is nearly unreasonable to claim to have produced a theory which is in perfect agreement with every scientific discovery (at least for now). Even the most accurate scientific theories in the 21st century have uncertainties, most notably General Relativity and Quantum mechanics. These theories, for example, aim to describe the same phenomena (or equivalent mechanical phenomena) in two separate regimes. While many people hold high levels of confidence in both theories, the two have been found to be irreconcilable. It has, in fact, been proposed that the only way this problem can be overcome is if one (or both) of these theories is modified or abandoned. But, this is only possible if one (or both) of these theories is "disproved" . This is not necessarily a foreign thought. A lot of evidence, both experimental and observational, already seem to disagree with these theories. Unfortunately, abandoning one theory means having to develop a new and better theory. This has proven to be a huge task, and many scientists are preferring to either reform or modify the current theories.
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
No one has successfully disproved the germ theory of disease, which states that microorganisms can cause infectious diseases. This theory has been supported by a large body of scientific evidence and is widely accepted in the field of microbiology and medicine.
No, the law of conservation of energy has not been disproved. It is a fundamental principle in physics that states that energy cannot be created or destroyed, only transformed into different forms. This law has been widely supported by numerous experiments and observations.
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).

One key aspect of Democritus' theory of the cosmos that has been disproved is his idea of atoms as indivisible and unchangeable particles. Modern physics has shown that atoms can be divided into subatomic particles and can also undergo changes through nuclear reactions and other processes. Additionally, Democritus' view of an infinite number of worlds with different properties has not been supported by observational evidence.
A water molecule (H₂O) has a molecular weight of approximately 18 Daltons. This is calculated by adding the atomic weights of its constituent atoms: two hydrogen atoms (about 1 Dalton each) and one oxygen atom (about 16 Daltons). Therefore, the total is roughly 2 + 16 = 18 Daltons.
Yes, in fact many, many times. There is much more evidence supporting Creation, meanwhile evolution has too many impossible components associated. Any way you put it, life springing from amino acids is impossible, because the cell would die. Also, if monkeys evolved into humans, why are monkeys still existing? The so-called fossils have all been either individually disproven or just fragments of a skeleton, like teeth.
For a short time it was speculated that LeBron James had six toes in his right foot. This rumor has been disproved however.
