need answer to the following: for each molecular compounds, write the name corresponding name or write chemical formula to:
A)nitrogen pentasulfide
B)diphosphorus pentasulfide
C) AS2S3
D)PBr5
NS6
P2S6
C?
Phosphorus tetrabromide
Need to correct response by Anon.
Penta means 5
tetra means 4
nitrogen pentasulfide would be, following the name, NS5. I haen't heard of this compound. I would expect a N/S compound to be N2S5 (simiilar to P2S5 in the next compound); however, I assume that name would be dinitrogen pentasulfide.
Diphosphorus pentasulfide is P2S5.
AS2S3 doesn't mean a thing to me. You may have made a typo and it should have been written as As2S3. That compound is diarsenic trisulfide.
PBr5 is phosphorus pentabromide.
A) To write the chemical formula for nitrogen pentasulfide, we need to determine the valence or oxidation states of each element.
Since nitrogen (N) is in group 15 of the periodic table, it has a valence of -3. Sulfur (S) is in group 16 and has a valence of -2.
To balance out the charges, we need 5 sulfide ions (-2 charge each) for every nitrogen ion (-3 charge).
Therefore, the chemical formula for nitrogen pentasulfide is N2S5.
B) To write the chemical formula for diphosphorus pentasulfide, we follow a similar approach.
Since phosphorus (P) is in group 15 of the periodic table, it also has a valence of -3.
For phosphorus pentasulfide, we need 2 phosphorus ions (-3 charge each) for every 5 sulfur ions (-2 charge each) to balance out the charges.
Therefore, the chemical formula for diphosphorus pentasulfide is P2S5.
C) AS2S3 is the chemical formula for the compound called arsenic trisulfide. Arsenic (As) is a metalloid in group 15, and sulfur (S) is a nonmetal in group 16.
D) The chemical formula for PBr5 is phosphorus pentabromide. Phosphorus (P) has a valence of -3, and bromide (Br) has a valence of -1.
To balance the charges, we need 5 bromide ions (-1 charge each) for every phosphorus ion (-3 charge).
Therefore, the chemical formula for phosphorus pentabromide is PBr5.
To determine the corresponding name or chemical formula for each given molecular compound, follow these steps:
A) Nitrogen Pentasulfide:
To find the corresponding name for this compound, we can break down its name based on the prefixes and suffixes involved. Start by identifying the elements involved: nitrogen and sulfur. The prefix "penta-" indicates that there are five sulfur atoms.
Therefore, the chemical formula for nitrogen pentasulfide is N2S5.
B) Diphosphorus Pentasulfide:
Similarly, for this compound, "di-" indicates that there are two phosphorus atoms, and "penta-" indicates five sulfur atoms.
Therefore, the chemical formula for diphosphorus pentasulfide is P2S5.
C) AS2S3:
In this given chemical formula, AS represents the elements arsenic (As) and sulfur (S). The subscripts indicate the number of atoms for each element. Therefore, there are two arsenic atoms and three sulfur atoms.
Thus, the name for AS2S3 is diarsenic trisulfide.
D) PBr5:
In this chemical formula, P represents the element phosphorus (P), and Br represents the element bromine (Br). The subscript "5" indicates that there are five bromine atoms.
Consequently, the name for PBr5 is phosphorus pentabromide.
By following these steps and considering the prefixes and elements involved, you can determine the corresponding names or chemical formulas for the given compounds.
