Answer:
The central atom has 3 electron domains.
Explanation:
According to the Valence Shell electron pair repulsion theory (VSEPR) put forward by Gillespie and Nyholm in 1957, the shape of a molecule is determined by repulsion between all the electron pairs (electron domains) present in the valence shell.
The electron pairs or electron domains are known to position themselves as far apart in space as possible in order to minimize repulsions.
Hence, when the central atom of a molecule contains three electron domains, they are positioned at an angle of 120° from each other to minimize repulsions. Hence the answer.
Answer:
7.85 g/cm³
Explanation:
Density is Mass/Volume
The mass is 212 grams
The volume is 27 cm³ (3 x 3 x 3 = 27)
212/27 = 7.851851852
We can estimate this to 7.85 g/cm³
