Answer:
<h2>70.27 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>70.27 moles</h3>
Hope this helps you
Explanation:
This atom is on the almost extreme right of the 2nd period of the periodic table (except for the stable element on the extreme right). This means it has the highest mass number of the unstable elements of the period. It thus attracts its electron clouds more strongly that the elements to the left of the period . This means it can gain an atom easily ( this is what is called electronegativity – tendency to attract an electron) than is can lose an electron. In addition, it only needs to acquire one electron to achieve a stable electron configuration (8) in its valence shell.
Due to these, it is hard for the atoms to lose an electron which is why it has a high ionization energy- the energy required to lose an electron.

Answer:
Strong acids and bases both denature proteins by severing disulphide bonds and at higher temperatures, can break proteins into peptides, or even individual amino acids.
Answer:
Since they are in a geostationary orbit, the GOES satellites provide continuous monitoring of the Earth's surface. They are able to constantly monitor the life cycle of significant weather such as hurricanes, tornadoes, flash floods, and hail storms.
Answer:
(D) (I) the H—X bond is stronger than the H—Y bond, and (II) X is less electronegative than Y.
Explanation:
A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A large Ka value also means the formation of products in the reaction is favored. As the electronegativity of an atom increases from left to right across a row, the acidity increases.
The higher the electronegativity of an atom, greater is its tendency to pull towards itself the pair of electrons that form the bond. This, in true effect, leads to a reduction in the bond length and therefore makes it harder cleave.
