Three resonance structures can be drawn for the allyl cation while two resonance structures can be drawn for the amidate ion.
Sometimes, we cannot fully describe the bonding in a chemical specie using a single chemical structure. In such cases, we have to use a number of structures which cooperatively represent the actual bonding in the molecule. These structures are called resonance or canonical structures.
The resonance structures of the allyl cation and the amidate ion are shown in the images attached to this answer. These structures show the different bonding extremes in these organic ions.

Answer:
0.36g of Al
0.64g of S
Explanation:
Let us write a balanced equation for the decomposition of aluminium sulfide Al2S3. This is shown below:
Al2S3 —> 2Al + 3S
Molar Mass of Al2S3 = (2x27) + (3x32) = 54 + 96 = 150g/mol
Molar Mass of Al = 27g/mol
Mass of Al from the balanced equation = 2 x 27 = 54g
Molar Mass of S = 32g/mol
Mass of S from the balanced equation = 3 x 32 = 96g
Now we can obtain the mass of Al and S produce as follows:
For Al:
From the equation,
150g of Al2S3 produced 54g of Al.
Therefore, 1g of Al2S3 will produce = 54/150 = 0.36g of Al.
For S:
From the equation,
150g of Al2S3 produced 96g of S.
Therefore, 1g of Al2S3 will produce = 96/150 = 0.64g of S
Answer:
Uniformitarianism- A theory that geologic process that occur today are similar to those that have occurred in the past
Trace Fossil- A fossil of a foot or trail or other travel of an animal rather than of the animal itself
Plants take nitrogen from the soil by absorption through their roots as amino acids, nitrate ions, nitrite ions, or ammonium ions. Plants do not get their nitrogen directly from the air.
