H2O has a bent structure. The oxygen atom is in the center, and the hydrogen atoms are attached but pointing downward. It's not linear because there are two unshared pairs of electrons on oxygen that take up their own spaces.
Answer:
Conservation of Mass
Explanation:
Conservation of Mass -
According to the works of Antoine Lavoisier , he stated that , mass is always conserved in a chemical reaction .
For example ,
carbon reacts with oxygen , it forms carbon dioxide ,
But , by using the principle of conservation of mass ,
mass can not created or be destroyed , hence , the mass of the initial state and final remains constant , there is only the transfer of mass or matter .
The volume of chlorine required is 7.71 L.
The reaction between phosphorus and chlorine is:
2P + 5Cl₂→ 5PCl₅
Therefore, 2 moles of P requires 5 moles of chlorine to react with it.
Given mass of P =3.39 g
Molar mass of P=30.97 g/mol
No. of moles of P = given mass/ molar mass = 3.39 / 30.97 = 0.109 moles
2 moles of P requires 5 moles of chlorine
0.109 moles of P will require 0.109 x 5/2 = 0.2725 moles of chlorine
According to ideal gas equation
PV=nRT
2.04 x V = 0.2725 x 0.0821 x 703
V = 0.2725 x 0.0821 x 703 / 2.04
V = 7.71L
