Final answer:

The formulas are CO2 for carbon dioxide, SiCl4 for silicon tetrachloride, IBr3 for iodine tribromide, and NO2 for nitrogen dioxide.

Step-by-step explanation:

To write the formula for each of these molecular compounds, we need to know the number of atoms of each element present in a molecule.

  • Carbon dioxide is made up of one carbon atom and two oxygen atoms. Its formula is CO2.
  • Silicon tetrachloride consists of one silicon atom and four chlorine atoms. The formula is SiCl4.
  • Iodine tribromide contains one iodine atom and three bromine atoms, giving us the formula IBr3.
  • For nitrogen dioxide, there is one nitrogen atom and two oxygen atoms, which makes the formula NO2.
