There are 48 hydrogen atoms, 24 carbon atoms, and 12 oxygen atoms, also 12 molecules of acetaldehyde were produced in the reaction.

The equation of the reaction is;

12C2H4 + 6O2 ------> 12 CH3CHO

In order to approach this problem, the balanced reaction equation is the first step. There are 12 ethylene molecules and six oxygen molecules. These will combine as shown.

There number of atoms involved are as follows;

H = 48

C = 24

O = 12

There are 12 molecules of acetaldehyde produced in the reaction.

The entropy change for a real, irreversible process is equal to:______.

taurus [48]

Answer:

The entropy change for a real, irreversible process is equal to zero.

The correct option is 'c'.

Explanation:

Lets look around all the given options -:

(a) the entropy change for a theoretical reversible process with the same initial and final states , since the entropy change is equal and opposite in reversible process , thus this option in not correct.

(b) equal to the entropy change for the same process performed reversibly ONLY if the process can be reversed at all. Since , the change is same as well as opposite too . Therefore , this statement is also not true .

(c) zero. This option is true because We generate more entropy in an irreversible process. Because no heat moves into or out of the surroundings during the procedure, the entropy change of the surroundings is zero.

(d) impossible to tell. This option is invalid , thus incorrect .

Hence , the correct option is 'c' that is zero.

What happens if you try to move the atoms very close to each other?

stellarik [79]

They push away from each other or repel due to the same charge they have.
