b
the color of lines
Explanation:
on the atomic spectrum for an atom
States of matter are determined by temperature. When the temperature is more cold, the particles move less. The colder the temperature, the more solid something becomes. Because the particles are in fixed positions, they do not move much, they are colder, and they are solid. Also, you cannot pass your hand through locked atoms. If you swipe your hand through water or gas, it parts. Solids, however, are fixed and cannot be passed by without significant force to break it.
PH + pOH = 14
11.8 + pOH = 14
pOH = 14 - 11.8
pOH = 2.2
[OH-] = 10 ^- pOH
[OH-] = 10 ^- 2.2
[OH-] = <span>6.33 x 10^-3 M

Answer B
hope this helps!
Answer:
2:a-heterogenous
b-homogenous
c-heterogenous
d-heterogenous with water
3:Filtration is used to separate insoluble particles from a solution
Distillation is used to separate liquids with close but different boiling points e.g water and ethanol
Explanation:
2: homogenous mixtures form a uniform layer meaning that a mixture containing more than one layer is heterogenous
