Answer:
you need to include the bottom portion, not enough info
Explanation:
Helium,it has an atomic mass of 4,which means total no. of protons and neutrons,so I think you meant 2 protons and an atomic mass of 4
The electron domain geometry is trigonal bipyramidal while the molecular geometry of the compound is seesaw.
The shapes of molecules is determined by the number of electron pairs on the valence shell of the central atom in the molecule. These electron domains include lone pairs and bond pairs.
The lone pairs only contribute towards the electron domain geometry and not the molecular geometry. SCl4 has five electron domains hence its electron domain geometry is trigonal bipyramidal. The molecular geometry of the compound is seesaw.

Answer:
Scientists debated the theories with each other and compared the theories with scientific observations
Speed is calculated using the formula distance divided by time. For a distance of 26.2 miles, and a time of 3 hours and 40 minutes, we first convert the time to make it solely in terms of hours. 40 minutes is 2/3 of an hour, so this is a total time of 3 2/3 or 11/3 hours. If we divide 26.2 miles by 11/3 hours, we get a resulting speed of 7.14 miles/hour.
