They both break down and and erode
Answer:
The volume occupied by molecules becomes a significant part of the total volume.
Attractions between molecules cause a reduction in volume.
Explanation:
C is wrong. The masses of molecules are constant.
Answer: Rows are the horizontal rows and Columns are the vertical rows.
Answer:
True
It is true that he size of coupling constants (J values) depend on three factors:
a. Through bond distance between the protons.
b. Angle between the two C-H bonds.
c. Electronegative substituents.
Explanation:
With the increase in the valence angle the coupling constant reduces. The distance between the carbon atoms also influence coupling constant. With increase in bond length, the coupling constant decreases. Also the more an atom is electronegative, the lesser is the coupling constant
Thus, it is true that he size of coupling constants (J values) depend on three factors:
a. Through bond distance between the protons.
b. Angle between the two C-H bonds.
c. Electronegative substituents.
