The semester just started and we are talking about the scientific method and laws, hypotheses/theories and etc. There is one question that I quite don't understand in my chem book though:
What is wrong with the statement, "It is just a theory"?
thanks!

"Theory" in the scientific sense has a very different meaning than "theory" in the everyday sense. A scientific theory explains natural phenomena and has empirical evdence to back it up. If it had been conclusively disproven, it wouldn't exist at all. So, in the context of chemistry, "Just a theory" could at times be construed to mean something like "just a fact."
Something that would fit the conventional sense of "theory" (something more like an educated guess with little evidence to back it up ) would be an hypothesis.

Firstly, a theory is generally a rather involve scientific statement that has been tested and holds up to rigorous challenges.
Typically, this statement would refer to what is known as a hypothesis, which is a very weak version of a theory. It is also incomplete.

In Science, there are no theories. Everything is backed up by some sort of scientific explanation.

think of of it this way. in case you mandatory to study piles of footballs and table-tennis balls, you're able to prefer to correctly known how many have been in each and each and each and each pile, now no longer the load of the pile. If there have been equivalent numbers, for sure the pile of footballs could weigh greater effective. comparable with molecules. The mole is the quantity of regardless of-it-is that comes with a particular style of atoms (see diverse answerers for the truthfully extensive type). So a mole of hydrogen (H2 = a uncomplicated molecule) weighs a lot below a mole of lead sulphate (working occasion). The mole isn't a sequence mass, as a result, yet a diverse mass for each substance in accordance to its molecular weight. on the comparable time as subject concerns react chemically, that's the numbers of dissimilar molecules that bear in mind. it extremely is why the mole is important in chemistry.

theorys take a lot of time to prove and they have been challenged many times and are shown to be true
