Want this question answered?
The modern periodic table was derived out of scientific curiosity. The table was meant to explain why certain elements would combine with certain others but not all others.
If a hypothesis does not explain an observation, it is rejected. A hypothesis is basically just an educated guess, so it could be wrong, or right.
yes because they give you info
Is not complete becuase not everythin is correct
Ideally, complete combustion. In practice it isn't always, which is why cars have catalytic converters.
Observation.
Forming a hypothesis - to explain the observation.

That is true. Science tries to make sense of what is observed, to explain the universe in which we live. Until you make an observation, there is nothing to explain.
When you are using the scientific method, you would try to imagine a hypothesis which explains an observation, but you might not succeed. A hypothesis that does not explain an observation would be considered a failed hypothesis. You would then need to invent a different hypothesis.
I have no clue
An observation.
You must observe to explain.
By observation (and by knowing "everything").

A tentative explanation in research is called a hypothesis. The hypothesis is based on observation. The general explanation of the observation is called a theory. In other words, a theory is the result of testing a hypothesis.
