Answer:
Their pH is less than 7
Explanation:
Both of these compounds pHs are greater than 7.
Hydrogen burns with oxygen as in combustion reaction to form water.
H₂ + O₂ → H₂O
The van't Hoff factor is the ratio between the amount of particles produced when a substance is dissolved and the amount of substance being dissolved. If ionization is 0 percent then it would mean that the substance do not dissociate into particles so the van't Hoff factor would be 1. However, when the percent ionization is 100%, then it fully dissociates into ions. For H2SO4 at 100% ionization, the vant hoff factor should be three, two hydrogen ions and one sulfate ion.
My answer will be C. Law of Original lateral continuity. :)
P is a element called Phosphorus.
Cl is chlorine. Since their is 5 of chlorine, we call it pentachloride. Penta means 5, as in the shape PENTAgon.
Compound Name: Phosphorus pentachloride
