Answer:

d) none of the above

Explanation:

The law that describes the relationship between pressure and volume of an ideal gas (under constant temperature and amount of substance) is Boyle's law.

It states that pressure is inversely proportional to the volume. This would mean that a graph of P vs 1/V would be a line.

See the attached picture for a graph of P vs V.

Given the balanced equation representing a reaction:

 As  aluminium   loses 12 moles  of electrons  oxygen   gain  12 moles of electrons.

Explanation
  4Al +  3 O2→ Al2O3
  first write the ions of  Aluminium  and  oxygen

that is, Aluminium  ion is = Al^3+
              oxygen   ion  is =  O^2-
therefore  one  atom  of Al   loses   3  electrons  moles  while
                one atom of  O gain  2  electrons  moles
                
from equation above there  a total of number of Al atom are 4 =( 1 x4=4)  atoms   while
                                                Oxygen atoms  are  6= ( 3 x2=6) atoms
 
therefore the total  number of Moles of Al lost is = 3  x 4 = 12 moles of                       electrons
     

  total  number of moles of O gained  =  2 x6 = 12 moles  of electrons

A gaseous system undergoes a change in temperature and volume. What is the entropy change for a particle in this system if the f
deff fn [24]

Explanation:

Entropy means the amount of randomness present within the molecules of the body of a substance.

Relation between entropy and microstate is as follows.

           S = K_{b} \times ln \Omega

where,      S = entropy

             K_{b} = Boltzmann constant

             \Omega = number of microstates

This equation only holds good when the system is neither losing or gaining energy. And, in the given situation we assume that the system is neither gaining or losing energy.

Also, let us assume that \Omega = 1, and \Omega' = 0.833

Therefore, change in entropy will be calculated as follows.

     \Delta S = K_{b} \times ln \Omega' - K_{b} \times ln \Omega

                 = 1.38 \times 10^{-23} \times ln(0.833) - 1.38 \times 10^{-23} \times \times ln(1)

                 = 1.38 \times 10^{-23} \times (-0.182)

                 = -0.251 \times 10^{-23}

or,             = -2.51 \times 10^{-24}

Thus, we can conclude that the entropy change for a particle in the given system is -2.51 \times 10^{-24} J/K particle.
