Well for this questions the method used by scientist are tecnicaly different than others well most suit of what atoms they could find in their place so its easier. But most do say that they put a chemical and if it bubbles its a mixture and if their are no ubble it is a pure substance
Yes, scientists in the 18th and early 19th centuries believed heat was a substance called caloric, which was thought to flow from hotter to colder bodies. This theory was later replaced by the kinetic theory of heat in the mid-19th century.

The Noble gases were known as inert gases because it was believed that they were completely unreactive. This is no longer true as scientists have discovered compounds containing noble gas elements.
People once believed that noble gases couldn't chemically react at all. For this reason, they were called inert gases. They were also clustered under Group 0 in the old periodic table because scientists believed that the gases have zero valence electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.
In 2008, scientists discovered the fossils of an animal they believed was an ancestor of today's whales. The unique feature of this animal was that it had legs and possible spent a lot of time on land as well as in the water.
