Answer:
a. H20,because it experiences hydrogen bonding.
Potassium and Chloride forms an ionic bond.
(K+) + (Cl-) = KCl
Potassium is under Group IA (Alkali Metal), wherein elements under this group can easily lose electrons.
Chlorine is under Group VII (Halogens), in which these elements can gain electrons easily.
The inner shell electrons on potassium will merge with the outer shell of electrons of chlorine to make potassium chloride.
Answer:
4)Particle Arrangement
Explanation:
When solid carbon dioxide CO₂ will evaporate in gaseous carbon dioxide CO₂ the particles arrangement will change from ordered in solid state to completely disordered in gaseous state.
Bond type, gram formula mass and molecular polarity are not changed in the described physical transformation.
Answer: The pH at the equivalence point for the titration will be 0.65.
Solution:
Let the concentration of be x
Initial concentration of , c = 0.230 M
at eq'm c-x x x
Expression of :
Since ,methyl-amine is a weak base,c>>x so .
Solving for x, we get:
Given, HCl with 0.230 M , it dissociates fully in water which means = 0.230 M
will result in neutral solution, since
Remaining after neutralizing ions
The pH at the equivalence point for the titration will be 0.65.
The answer would be 1,176. you solve by using (L*H*W)
