What are the formulas for the following compounds?
Nitrogen triiodide
iodine monochloride
tetraiodine nonaoxide
Could you look at nitrogen triiodide and make a good guess that the formula is NI3?
Or iodine monochloride is ICl?
or tetraiodine nonaoxide is ??? (nona stnads for 9)
To find the formulas for the given compounds, you'll need to understand the rules for naming and writing chemical formulas.
1. Nitrogen Triiodide:
This compound consists of nitrogen and iodine. To determine the formula, you need to consider the charges of the elements. Nitrogen typically forms compounds with a charge of -3, while iodine forms compounds with a charge of -1. Since there are three iodine atoms in the compound, their total charge would be -3, which can be neutralized by a single nitrogen atom. Therefore, the formula for Nitrogen Triiodide is NI3.
2. Iodine Monochloride:
This compound consists of iodine and chlorine. Similar to the previous compound, iodine has a charge of -1, while chlorine has a charge of -1. Since the charges are balanced, the formula for Iodine Monochloride is ICl.
3. Tetraiodine Nonaoxide:
This compound consists of iodine and oxygen. The prefix "tetra-" indicates that there are four iodine atoms, and "nona-" indicates that there are nine oxygen atoms. The charges of iodine and oxygen are -1 and -2, respectively. To balance the charges, four iodine atoms (with a total charge of -4) will combine with nine oxygen atoms (with a total charge of -18). The lowest common multiple of 4 and 18 is 36, so the formula will need 36 in the denominator to balance the charges. Therefore, the formula for Tetraiodine Nonaoxide is I4O9.
Remember, when determining formulas, you need to consider the charges of the elements involved and ensure that the total charge of the compound is neutral or zero.
