Answer:
<u>2.13</u> moles of AlCl3 are produced from 3.2 moles of Cl2
Explanation:
Moles : The amount of substance that contain as many particles as present in 12 grams of C-12.
The balanced equation for the reaction is :
This reaction shows the following :
2 mole Al = 3 mole Cl2 = 2 mole AlCl3
In question we are asked to calculate the moles of AlCl3 produced from Cl2
So, we will use only Cl2 andAlCl3 moles
3 mole Cl2 = 2 mole AlCl3
1 moles of Cl2 will give =
of AlCl3
3.2 moles of Cl2 will give =
of AlCl3
= 2.133 moles
Answer:
Ethane would have a higher boiling point.
Explanation:
In this case, for the lewis structures, we have to keep in mind that all atoms must have <u>8 electrons</u> (except hydrogen). Additionally, each carbon would have <u>4 valence electrons</u>, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.
Now, the main difference between methane and ethane is an <u>additional carbon</u>. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have <u>more area of interaction</u> for ethane. If we have more area of interaction we have to give <u>more energy</u> to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.
I hope it helps!
