Explanation:
In sodium phosphide
Electrons are transferred from atoms of sodium
to atoms of phosphorous .
This transfer makes the sodium atoms to loose electrons
and the phosphorus atoms to gain electrons
As a result, the sodium and phosphorus bond strongly each other with a ionic bond .
The bond formation occurs as shown :
Sodium looses one electron to form Na⁺¹.
Phosphorous gain electrons to form P³⁻.
So, now we have :
Na ⁺ P³⁻
After criss crossing we have :
Na₃P

Answer:
B
Explanation:
Chemistry is the study of matter, its composition and the changes it undergoes.
Answer:
V of Sulfur tetrafluoride is 17.2 L
Explanation:
Given data;
T = -6°C = 267K [1° C = 273 K]
n = 786 mmol of SF4 which is 0.786 mol
P = 1 atm
from ideal gas law we have
PV = nRT
where n is mole, R is gas constant, V is volume
V of Sulfur tetrafluoride is 17.2 L
