The correct answer among the choices given is the first option.The teacher most likely is talking about distillation of a mixture. Distillation is a unit operation that separates component substances from a liquid mixture which is shown by the teacher. Also, the most common purifying technique in the production of gasoline is by this process.
Answer:
Phosphorus makes 5 bonds with other atoms
Explanation:
has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).
These valence electrons are used to draw Lewis structure of .
Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)
Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of , it has been found that P makes total 5 bonds with rest of the atoms.
Lewis structure of along with formal charge (in parentheses) has been given below.
