Imagine that you can see individual molecules. You watch a small collection of molecules that are moving around slowly while vibrating and bumping against
each other. The slower moving molecules then start to line up, but as they do so
their vibrations increase. Soon all the molecules are aligned and vibrating about
fixed positions. What is happening?

Deposition is the transition of matter going from gas to solid without passing through the liquid phase.a.) gas—-> solid

Any vitamins or supplements can be obtained without prescription and are widely used as alternative from western medications. most supplements are not valued by the fda or any other drug and food agencies.

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
