Answer:
The structure is shown in the diagram.
Explanation:
Lewis structure : In order to draw Lewis structure we will calculate the total number of valence electrons in the molecule.
The valence electrons from Cl : 7
The valence electrons from O = 3 X 6 = 18
Charge negative so more electrons = 2
total electrons = 7 + 18 +2 = 27
Now we will distribute the electrons on each atom and in between atoms as shown in the diagram.
I can't remember any of the weights of the individual elements but here is how you solve it:
Molecular weight of copper + nitrogen + 3 oxygens = molecular weight of the compound.
M = moles / liter
.350 moles / 1 liter
Do .350 moles / liter x the molecular weight (g / mole) of the compound = the answer in g / L
Answer:
21.4 L
Explanation:
Given data:
Volume of carbon dioxide produced = ?
Volume of oxygen = 37.4 L
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
It is known that,
1 mole = 22.414 L
There are 7 moles of oxygen = 7×22.414 = 156.9 L
There are 4 moles of carbon dioxide = 4×22.414 = 89.66 L
Now we will compare:
O₂ : CO₂
156.9 : 89.66
37.4 : 89.66/156.9×37.4 = 21.4 L
So from 37.4 L of oxygen 21.4 L of carbon dioxide is produced.
Answer:
In ionic bond one element should be metal and next should be non metal. in covalent both element should be met Alice. if there valence electron is less than 4 than it is metal or more than 4 it is non metal.
