Answer:
Ionic bonding occurs when atoms either gain or lose one or more valence electrons, resulting in the atom having either a negative or positive charge.
Through ionic bonding, an atom of each element will combine with the other to form a molecule, which is more stable since it now has a zero charge.
Explanation:
Arrhenius model considers a base a compound that produces OH(-)
H2SO4 produces H(+) and is an acid
C6H12O6 is an organic product, sugar, that does not produce OH(-)
HOClO2 = HClO3, which produces H(+) and is an acid
NH3 is believed to ionize in water and produce NH4(+) and OH(-).
As per this the answer is NH3.
Nevertheless, NH3 is not a good example of bases as per Arrhenius model, because it is not so evident that NH3 produces OH(-).
Answer:
pH of the solution = 9.45
Explanation:
pKb = 8.57
pKb = -logKb
Kb = antilog pkb
ICE table for the ionization of pyrodine is:
initial 0.435 0 0
equi. 0.435 - x x x
so,
![k_b =\frac{ [C_5H_5NH^+][OH^-]}{[C_5H_5N]}\\1.78\times 10^{-9}=\frac{x^2}{0.453 - x}](https://tex.z-dn.net/?f=k_b%20%3D%5Cfrac%7B%20%5BC_5H_5NH%5E%2B%5D%5BOH%5E-%5D%7D%7B%5BC_5H_5N%5D%7D%5C%5C1.78%5Ctimes%2010%5E%7B-9%7D%3D%5Cfrac%7Bx%5E2%7D%7B0.453%20-%20x%7D)
As kb is very less that means there is very less ionization, hence x can be ignored as compared to 0.435
pOH = -log[OH-]
![pOH = -log[2.78\times 10^{-5}]\\=4.55](https://tex.z-dn.net/?f=pOH%20%3D%20-log%5B2.78%5Ctimes%2010%5E%7B-5%7D%5D%5C%5C%3D4.55)
pH = 14 - pOH
= 14 - 4.55
= 9.45
Answer
Sounds travel slowest in gasses so it would be air
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
