Answer:
2Na + Cl2 ------> 2NaCl
4H2O2 --------> 4H2O + 2O2
CH4 + 2O2 -------> CO2 + 2H2O
Explanation:
Answer:
Explanation: because more is always better
A proper chemical storage includes the following;
-
Management – this includes of managing the
storage area of the chemical and how they are stored base on their difference
and property
-
Compliance – this is the action needed in means
of having to be able to understand the properties of the chemical in order to
know what action is needed to engaged on
Let's assume that change of pressure of PCl₅ is X
According to the ICE table,
PCl₅(g) ⇄ PCl₃(g) + Cl₂(g)
Initial Pressure 0.123 - -
Change -X +X +X
Equilibrium 0.123 - X X X
Kp = Ppcl₃(g) x Pcl₂(g) / Ppcl₅(g)
by substitution,
0.0121 = X × X / (0.123 - X)
0.0121 × (0.123 - X) = X²
1.4883 × 10⁻³ - 0.0121X = X²
X² + 0.0121X - 1.4883 × 10⁻³ = 0
X₁ = 0.03735 or X₂ = -0.03865
X cannot be a negative value since X is a pressure.
Hence,
X = 0.03735 atm
Hence, partial pressure of PCl₃ is 0.03735 atm
