Answer:
A
Explanation:
Recall that a mole of any substance contains 6.02 × 10²³ amounts of that substance.
In other words, a mole of gold atoms contains 6.02 × 10²³ gold atoms.
Hence, by dimensional analysis, we have that:
![\displaystyle 4.81\times 10^{21} \text{ Au} \cdot \frac{1\text{ mol Au}}{6.02\times 10^{23} \text{ Au}} = 7.99\times 10^{-3} \text{ mol Au}](https://tex.z-dn.net/?f=%5Cdisplaystyle%204.81%5Ctimes%2010%5E%7B21%7D%20%5Ctext%7B%20Au%7D%20%5Ccdot%20%5Cfrac%7B1%5Ctext%7B%20mol%20Au%7D%7D%7B6.02%5Ctimes%2010%5E%7B23%7D%20%5Ctext%7B%20Au%7D%7D%20%3D%207.99%5Ctimes%2010%5E%7B-3%7D%20%5Ctext%7B%20mol%20Au%7D)
Therefore, there is about 7.99 × 10⁻³ moles of gold present in the sample.
In conclusion, the answer is A.
Answer:
There is an overall release of energy when bonds form.
Explanation:
There is a general release of energy when bonds form. This energy is called bond energy.
Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.
