Why is pure silicon a poor conductor at room temperature?

1 answer:

5 0

Because pure silicon is a perfect semiconductor.

For room temperature, it rarely conducts, you can search for the threshold temperature, the characteristic equation is fairly complicated.

Compare the strength of intermolecular forces in no2 to the strength of intermolecular forces in n2

matrenka [14]

N2 is non-polar molecules,
NO2 is polar molecules that have slightly positive charge on N and slightly negative on O, so <span>intermolecular forces are stronger in NO2</span>

why would you expect to see similar rocks and rock structures on two land masses that were connected at one time?

tangare [24]

If they were connected at one time than you would expect to find similar rock structures because they eroded, weathered, and we’re formed most likely at the same time out of the same material. So basically since they were near each other they were under the same or similar conditions.

CH₃-CH(-CH₃)-CH(-CH₃)-CH₃

2,3-dimethyl-1-butane

Explanation:

We have the following chemical reaction:

CH₂=C(-CH₃)-CH(-CH₃)-CH₃ + H₂ → CH₃-CH(-CH₃)-CH(-CH₃)-CH₃

So 2,3-dimethyl-1-butene will react with hydrogen to produce 2,3-dimethyl-1-butane.
