The numerical value of the equilibrium constant, Kc, for the following gas phase reaction is 0.50 at a certain temperature. When a certain reaction mixture reaches equilibrium, the concentration of O2 is found to be 2.0 M, while the concentration of SO3 is found to be 10 M. What is the equilibrium concentration of SO2 in this mixture

10 M

Explanation:

The Balanced Reaction is;

2SO2 + O2 <> 2SO3

As Equilibrium Concentration of O2 is given to be;

[O2] = 2.0 M

And the Equilibrium Concentration of SO3 is given to be

[SO3] = 10 M

With the Equilibrium Constant as;

Kc = 0.50

Then we can solve for the concentration of SO2 as,

Kc = [SO3]2 / ( [SO2]2 × [O2] )

0.50 = (10)2 / ( [SO2]2 × 2.0 )

0.50( [SO2]2 × 2.0 )

[SO2]2 = 100

Solving for SO2 we get,

[SO2] = (100)1/2 = 10 M

Therefore, the Equilibrium Concentration of SO2 in the mixture is 10 M

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
