Answer:
you can do a celser lava lamp its really easy, i can give you a link if you need?
Explanation:
Answer:
5 point) Chemists used systems and order because they study the basic unit of all forms of matter, which is the atom . However, there are several different kinds of atoms, called elements . Chemists organize these elements using the periodic table .
Explanation:
Answer : The correct option is, (C) 1.1
Solution : Given,
Initial moles of
= 1.0 mole
Initial volume of solution = 1.0 L
First we have to calculate the concentration
.


The given equilibrium reaction is,

Initially c 0
At equilibrium

The expression of
will be,
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)

where,
= degree of dissociation = 40 % = 0.4
Now put all the given values in the above expression, we get:



Therefore, the value of equilibrium constant for this reaction is, 1.1
Answer:
hope this answer will help you.
Similarities:
they both made sediment into soil
they both form the earth
they both made sediments have cracks
differences:
physical is reliant usually on contact with atmospheric condition
chemical transforms rocks into sediments while physical only breaks it down
chemical uses chemical reactions
