Well, you would need to know how to properly name these chemical compounds and elemental compounds, specifically ionic compounds.

1. H2 + I2 -> 2HI - Synthesis
2. 2Li + 2HCl -> 2LiCl + H2 - SR - Single replacement
3. Na2CO3 -> Na2O + CO2 - Decomposition
4. 2HgO -> 2Hg + O2 - Decomposition
5. Mg(OH)2 -> MgO + H2O - Decomposition
6. Cu + Cl2 -> CuCl2 - Synthesis
7. Ca(ClO3)2 -> CaCl2 + 3O2 - Decomposition.
8. 2Li + 2H2O -> 2LiOH + H2 - Single Replacement Reaction.

Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas. pcl3(g) + cl2(g) equilibrium reaction ar
vladimir1956 [14]

The question is incomplete, here is the complete question:

Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas:

PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)

A gas vessel is charged with a mixture of PCl_3(g) and Cl_2(g), which is allowed to equilibriate at 450 K. At equilibrium the partial pressures of the three gases are p_{PCl_3(g)} = 0.126 atm , p_{Cl_2(g)} = 0.156 atm , and p_{PCl_5(g)} = 1.60 atm. What is the value of K_p at this temperature?

<u>Answer:</u> The K_p for the given reaction is 81.4

<u>Explanation:</u>

For the given chemical equation:

PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)

The expression of K_p for above reaction follows:

K_p=\frac{p_{PCl_5}}{p_{Cl_2}\times p_{PCl_3}}

We are given:

p_{PCl_5}=1.60atm\\p_{PCl_3}=0.126atm\\p_{Cl_2}=0.156atm

Putting values in above equation, we get:

K_p=\frac{1.60}{0.156\times 0.126}\\\\K_p=81.4

Hence, the K_p for the given reaction is 81.4
