Answer:
Top-Toluene
Middle-Water
Bottom-Chloroform
Explication:
Chloroform is on the bottom layer because it is the densest liquid.
Toluene is on the top because it is the least dense.
Water is between the two because it’s density is between chloroform and toluene.
Explanation:
It is known that
is insoluble in water. As a result, plants are not able to absorb
readily through osmosis.
Therefore, the
in
would be released in acidic environments, using neutralization, Iron(III) ions can be released.
Hence, the easiest way is to add low concentrations of
to the soil is as follows.
Thus, we can conclude that
is soluble and is good for plants too.
Answer:
The periodic table can be use to determine the properties of new elements by organi the elements according to their numbers
Explanation:
Answer
The mole ratio is 1:1
The molar mass of potassium hydrogen phthalate (C8H5KO4) is 204.22g/mol
The mass of C8H5KO4 is 0.43g
The no of moles of C8H5KO4 = mass/molar mass
No of Moles of C8H5KO4 = 0.000210557242mol
From Mole ratio the no of mole of NaOH that reacted with C8H5KO4 0.000210557242
Therefore, molaroty of NaOH is mole of NaOH/the Volume in L
Molaroty if NaOH = 0.000210557242/0.02411 = 0.08733M
