Elements in the third row can break the octet rule
Answer:
Calcium chloride react with aluminum to produce calcium and aluminum chloride. This reaction takes place at a temperature of 600-700°C.
CaCl2+F2 -> CaF2 + Cl2
First, determine the number of moles of gold.
Number of moles = ![\frac{given mass in g}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bgiven%20mass%20in%20g%7D%7Bmolar%20mass%7D)
Given mass of gold =![6 \times 10^{9} g](https://tex.z-dn.net/?f=6%20%5Ctimes%2010%5E%7B9%7D%20g)
Molar mass of gold = 196.97 g/mol
Put the values,
Number of moles of gold = ![\frac{6 \times 10^{9} g}{196.97 g/mol}](https://tex.z-dn.net/?f=%5Cfrac%7B6%20%5Ctimes%2010%5E%7B9%7D%20g%7D%7B196.97%20g%2Fmol%7D)
=
or
Now, molarity = ![\frac{moles of solute}{volume of the solution in liters}](https://tex.z-dn.net/?f=%5Cfrac%7Bmoles%20of%20solute%7D%7Bvolume%20of%20the%20solution%20in%20liters%7D)
Put the values, volume of ocean =![1.5 \times 10^{21} L](https://tex.z-dn.net/?f=1.5%20%5Ctimes%2010%5E%7B21%7D%20L)
Molarity = ![\frac{3.046\times 10^{7} moles}{1.5 \times 10^{21} L}](https://tex.z-dn.net/?f=%5Cfrac%7B3.046%5Ctimes%2010%5E%7B7%7D%20moles%7D%7B1.5%20%5Ctimes%2010%5E%7B21%7D%20L%7D)
= ![2.03\times 10^{-14} M](https://tex.z-dn.net/?f=2.03%5Ctimes%2010%5E%7B-14%7D%20M)
Thus, average molar concentration = ![2.03\times 10^{-14} M](https://tex.z-dn.net/?f=2.03%5Ctimes%2010%5E%7B-14%7D%20M)
Explanation:
here's the answer to your question about
The bucket with lead added would replace more water, as it would require more volume to achieve the same mass.
