Write formulas for each of the following binary molecular compounds
c. tetraphosphorous decoxide
d. diarsenic trisulfide
555=131
To write the formulas for binary molecular compounds, we use prefixes to indicate the number of atoms of each element in the compound.
c. Tetraphosphorous Decoxide:
1. The prefix "tetra-" indicates that there are four phosphorous atoms.
2. The prefix "deco-" indicates that there are ten oxygen atoms.
Hence, the formula for tetraphosphorous decoxide is P4O10.
d. Diarsenic Trisulfide:
1. The prefix "di-" indicates that there are two arsenic atoms.
2. The prefix "tri-" indicates that there are three sulfur atoms.
Therefore, the formula for diarsenic trisulfide is As2S3.
