what did you notice about the way the soil particles sank in the water? how was it different from the way the soil and sand particles sank?
what does the soil look like in the "soil" bottle? how is it different from the soil in the "soil and sand" bottle?
in the "soil and sand" bottle, which type of soil is on the bottom? why?
the amount of each size particle in soil is the particle size distribution. do you think this is a good way to determine particle size distribution? why or why not?

i need asap! i don't know how to answer the questions because i messed up the "soil" bottle and it is due today.

Ethene molecular fórmula= c2h4molecular weight = 29.046g/molhope it : )

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

1. i don't know.2. bitter taste, feels slippery, contains hydroxide or produces it in a solution.3. 104.i don't know.5. electrons.hope this somewhat!
