An object's mass is less on<br> the Moon than it is on Earth.
vovikov84 [41]

Answer:

The mass of objects remains constant throughout the universe. This is because an object is made of he same amount of matter (atoms), no matter where you take it in the universe. If you take an object from the Earth to the moon, only the weight will change.

arsen [322]

Answer:

a solution of salt is homogeneous mixture

a sulution of muddy water is heterogeneous mixture

Explanation:

reason for salt and water as homogeneous mixture because water dissolves salt easily unlikely heterogeneous mixture in which water cannot dissolve mud in it

The equilibrium constant Kc for the decomposition of phosgene, COCl2, is 4.63x10^-3 at 527 C. Calculate the equilibrium partial
Studentka2010 [4]

<u>Answer:</u> The partial pressure of the CO,Cl_2\text{ and }COCl_2 are 0.352 atm, 0.352 atm and 0.408 atm respectively.

<u>Explanation:</u>

We are given:

K_c=4.63\times 10^{-3}

p_{COCl_2}=0.760atm

Relation of K_p with K_c is given by the formula:

K_p=K_c(RT)^{\Delta ng}

Where,

K_p = equilibrium constant in terms of partial pressure = ?

K_c = equilibrium constant in terms of concentration = 4.63\times 10^{-3}

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature = 527^oC=527+273=800K

\Delta ng = change in number of moles of gas particles = n_{products}-n_{reactants}=2-1=1

Putting values in above equation, we get:

K_p=4.63\times 10^{-3}\times (0.0821\times 800)^{1}\\\\K_p=0.304

The chemical reaction for the decomposition of phosgene follows the equation:

                   COCl_2(g)\rightleftharpoons CO(g)+Cl_2(g)

At t = 0          0.760            0     0  

At t=t_{eq}      0.760-x          x      x

The expression for K_p for the given reaction follows:

K_p=\frac{p_{CO}\times p_{Cl_2}}{p_{COCl_2}}

We are given:

K_p=0.304\\p_{COCl_2}=0.760-x\\p_{CO}=x\\p_{Cl_2}=x

Putting values in above equation, we get:

0.304=\frac{x\times x}{0.760-x}\\\\x=0.352,-0.656

Negative value of 'x' is neglected because partial pressure cannot be negative.

So, the partial pressure for the components at equilibrium are:

p_{COCl_2}=0.760-0.352=0.408atm\\\\p_{CO}=0.352atm\\\\p_{Cl_2}=0.352atm

Hence, the partial pressure of the CO,Cl_2\text{ and }COCl_2 are 0.352 atm, 0.352 atm and 0.408 atm respectively.
