Answer:
cannot be broken down further
Answer:
Yes
Explanation:
A molecular compound is that one which is composed of molecules formed by atoms of two or different elements. A pentacosane is an alkaline made of unbranched chain of 25 carbons atoms. It has applications in plant metabolite. The molecular formula of pentacosane is C₂₅H₅₂
The first dissociation for H2X:
H2X +H2O ↔ HX + H3O
initial 0.15 0 0
change -X +X +X
at equlibrium 0.15-X X X
because Ka1 is small we can assume neglect x in H2X concentration
Ka1 = [HX][H3O]/[H2X]
4.5x10^-6 =( X )(X) / (0.15)
X = √(4.5x10^-6*0.15)
∴X = 8.2 x 10-4 m
∴[HX] & [H3O] = 8.2x10^-4
the second dissociation of H2X
HX + H2O↔ X^2 + H3O
8.2x10^-4 Y 8.2x10^-4
Ka2 for Hx = 1.2x10^-11
Ka2 = [X2][H3O]/[HX]
1.2x10^-11= y (8.2x10^-4)*(8.2x10^-4)
∴y = 1.78x10^-5
∴[X^2] = 1.78x10^-5 m
Answer:k
Explanation:
Atomic theory would be the theory or explanation of the function of atoms and their relationship with each other.
