A chemist needs to know the mass of a sample of aniline to 3 significant digits. She puts the sample on a digital scale. This is what the scale shows: 0 0 100.4
If this measurement is precise enough for the chemist, round it to 3 significant digits.
Otherwise, press the "No solution" button.

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

That is a lot of moles that you have

The higher the temperature, the increased rate constant for a reaction.(positive linear association)

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
