Answer : The equilibrium partial pressure of Cl₂ at 25°C is, 1.98 atm

Explanation :

For the given chemical reaction:

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

The expression of $K_p$ for above reaction follows:

$K_p=\frac{P_{PCl_3}\times P_{Cl_2}}{P_{PCl_5}}$

We are given:

$P_{PCl_5}=0.875atm$

$P_{PCl_3}=0.463atm$

$K_p=1.05$

Putting values in above equation, we get:

$1.05=\frac{0.463\times P_{Cl_2}}{0.875}\\\\P_{Cl_2}=1.98atm$

Thus, the equilibrium partial pressure of Cl₂ at 25°C is, 1.98 atm

Given 28.2 grams of an unknown substance, if the substance absorbs 2165 joules of energy and the temperature increases by 35 Kel

liubo4ka [24]

I think the answer should be 2.19 J/g*K. The specific heat means the energy absorbed by 1 g substance to increase 1 Kelvin temperature. And keep the unit the same.

Identify each of the following half-reactions as either an oxidation half-reaction or a reduction half-reaction. half-reaction i

Natasha2012 [34]

Answer: Oxidation reaction: $Al(s)\rightarrow Al^{3+}(aq)+3e^-$

Reduction reaction: $Sn^{2+}(aq)+2e^-\rightarrow Sn(s)$

Overall redox reaction : $2Al(s)+3Sn^{2+}(aq)\rightarrow 2Al^{3+}(aq)+3Sn(s)$

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

$Al(s)\rightarrow Al^{3+}(aq)+3e^-$

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

$Sn^{2+}(aq)+2e^-\rightarrow Sn(s)$

Overall redox reaction : $2Al(s)+3Sn^{2+}(aq)\rightarrow 2Al^{3+}(aq)+3Sn(s)$
