Answer: Option (b) is the correct answer.
Explanation:
Buffere is defined as the solution to whom when an acid or base is added then it resists any in change in pH of the solution.
This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. So, basically it keeps the concentration of both hydrogen ions and hydroxides equal. As a result, it helps in maintaining the pH of the solution.
And, the capacity of a buffer solution to resist the change is known as buffer capacity.
Thus, we can conclude that buffering capacity refers to the extent to which a buffer solution can counteract the effect of added acid or base.
Answer:
Yes it is a scientific model because it is an outlook of a winter outlook and winter is a season and a type of weather and weather is meteorology and meteorology is a type of science so yes it is a scientific model.
Explanation:
The correct response would be A. The slowest step that determines the speed(rate) of the overall reaction.
Answer:
Explanation:
1 . periodicity
repeating nature of atomic structure
Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.
2 . shell
location of an electron
Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high
3 . non-metals
high ionization energies
Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.
4 . noble gases
least reactive family
Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.
5 . neutral
charge on a neutron
Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons
6 . repel
like charges
Like charges repel one another
7 . attract
unlike charges
Unlike charges attracts. Positve attracts negative charges.
One, it's weather connects to science.
The more carbon dioxide can be related.
