Answer:
a) The molecule is always polar.
Explanation:
The molecule is always polar because of two reasons:
- all the bonds are polar due to the difference in electronegativity between carbon and hydrogen & carbon and chlorine.
AND IMPORTANTLY
- The molecule is asymmetrical meaning that the dipoles cannot cancel each other out (like they do in methane or carbon dioxide for example) so the net effect is a polar molecule.
Answer:
10.418*10²³
Explanation:
1) 6.022*10²³ moleculas in 1 mole PCl₅ (Avogadro's number);
2) in 1.73 moles: 6.022*10²³*1.73=10.418*10²³
