Question
part vi: name the following covalent compounds containing all nonmetals. remember to use prefixes.
part vii: write the formula for the following compounds.
PART VI:
For \(P_4O_{10}\):
- The prefix for \(4\) is "tetra -" and for \(10\) is "deca -".
- The first element is phosphorus (\(P\)) and the second is oxygen (\(O\)).
- So the name is tetraphosphorus decoxide.
For \(Cl_2O_7\):
- The prefix for \(2\) is "di -" and for \(7\) is "hepta -".
- The first element is chlorine (\(Cl\)) and the second is oxygen (\(O\)).
- So the name is dichlorine heptoxide.
For \(PF_3\):
- The prefix for \(1\) (implied for the first element when no prefix is written) is "mono -" (usually omitted for the first element).
- The prefix for \(3\) is "tri -".
- The first element is phosphorus (\(P\)) and the second is fluorine (\(F\)).
- So the name is phosphorus trifluoride.
For \(BI_3\):
- The prefix for \(1\) (implied for the first element) is "mono -" (omitted).
- The prefix for \(3\) is "tri -".
- The first element is boron (\(B\)) and the second is iodine (\(I\)).
- So the name is boron triiodide.
For \(N_2O\):
- The prefix for \(2\) is "di -" and for \(1\) (implied for the second element) is "mono -".
- The first element is nitrogen (\(N\)) and the second is oxygen (\(O\)).
- So the name is dinitrogen monoxide.
For \(SO_2\):
- The prefix for \(1\) (implied for the first element) is "mono -" (omitted).
- The prefix for \(2\) is "di -".
- The first element is sulfur (\(S\)) and the second is oxygen (\(O\)).
- So the name is sulfur dioxide.
PART VII:
For "carbon monoxide":
- "Mono -" indicates \(1\) oxygen atom and "carbon" is \(C\).
- So the formula is \(CO\).
For "sulfur trioxide":
- "Tri -" indicates \(3\) oxygen atoms and "sulfur" is \(S\).
- So the formula is \(SO_3\).
For "diphosphorus trioxide":
- "Di -" indicates \(2\) phosphorus atoms (\(P\)) and "tri -" indicates \(3\) oxygen atoms (\(O\)).
- So the formula is \(P_2O_3\).
For "sulfur hexafluoride":
- "Hexa -" indicates \(6\) fluorine atoms (\(F\)) and "sulfur" is \(S\).
- So the formula is \(SF_6\).
For "silicon tetrachloride":
- "Tetra -" indicates \(4\) chlorine atoms (\(Cl\)) and "silicon" is \(Si\).
- So the formula is \(SiCl_4\).
For "nitrogen monoxide":
- "Mono -" indicates \(1\) oxygen atom and "nitrogen" is \(N\).
- So the formula is \(NO\).
