Approximately how long do scientists think chemical evolution took?
about a billion years.
What is energy in a chemical change?
You think probable to chemical energy.
Why you think chemical symbols and formula are an important part of communication among scientists?
The Symbols provide a shorthand method for representing elements and compounds, and how they react with each other. The formula's represent compounds.
Is crushing charcoal into powder a physical or chemical change?
Chemical I think
What is a condensed statement of facts about a chemical reaction called?
You think probable to a chemical equation.
Approximately how long do scientists think chemical evolution took?

What do scientists think about the theory of evolution?
The overwhelming majority of scientists accept the theory of evolution by natural selection. Any scientists that do not accept the theory usually do so for religious reasons.

What do scientists think about the rate of evolution?
That it is quite variable across species and environments, but can be somewhat calculated within a rather wide margin of error. Your rate of evolution is many times slower than the bacterial rate for instance.
What do scientists make to show when they think speciation occurred?
Scientists use a variety of evidence to determine when they think speciation occurred. This includes analyzing fossils, studying genetic similarities and differences between different species, and observing patterns of geographic distribution and reproductive isolation. Additionally, scientists may also use techniques such as radiometric dating to estimate the age of fossils and the timing of speciation events.
