300
What "State" is an electron in when it rises off its ground state?
The Excited State.
300
If the elements are different, does that effect the color of the light that is given off from the heat added, like in the flame test? Explain why.
yes, because depending on its electrons level of energy ,determines the color of the photon.

How can you test if an element has conductivity?
connect it to a electrical circuit.

What do alkane, alkene, and alkyne have in common?
they all contain carbon atoms.

Is vanilla either made in a lab or grown, both organic in a farmers eyes? why or why not?
no, because vanilla made in a lab isn't natural and organic in a farmer's eyes is anything grown with NO unnatural fertilisers or any chemical harmful to the environment.

How is the boiling point of water here in Colorado different from a place at or below sea level? what is the normal (at sea level) temperature, and the temperature here?
Its different because we are above sea level/ a higher altitude and as you gain altitude your boiling point temperature lowers.
normal: 100 Celsius
here: 90 Celsius
400
would this be an alkane, alkene, or alkyne?
H H
C
H H
explain why?
an alkane because it has a single carbon bond.

Is sodium chloride organic in a chemists eyes? why or why not?
no, its inorganic because it doesn't contain a carbon bond.
