Answer/Explanation

Organism A does not have a membrane-bound nucleus, whereas organism C does
Organism C is heterotrophic (relies on other organisms for a food source) whereas organism A is autotrophic (synthesises its own food)

These observations suggest that organism A is prokaryotic and organism C is eukaryotic.

Eukaryotic organisms have membrane-bound organelles such as a nucleus. This is where the DNA is housed. In contrast, prokaryotes do not have membrane-bound organelles. their DNA molecule is housed in a region of the cytoplasm called the nucleoid that is not separated from the rest of the cytoplasm by a membrane.

Eukaryotic organisms are also mostly heterotrophic, meaning they need to consume other living things to synthesise their food (exceptions include green plants which synthesise their food by photosynthesis). Some prokaryotes can use energy from light or chemicals to synthesise their own food source. This means they are autotrophic.

tester [92]

The given question is incomplete. The complete question is:

The change in entropy is related to the change in the number of moles of gas molecules. Determine the change in moles of gas for each of the reactions and decide if the entropy increases decreases or has little to no change:

A. $K(s)+O_2(g)\rightarrow KO_2(s)$

B. $CO(g)+3H_2(g)\rightarrow CH_4(g)+H_2O(g)$

C. $CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$

D. $N_2O_2(g)\rightarrow 2NO(g)+O_2(g)$

Answer: A. $K(s)+O_2(g)\rightarrow KO_2(s)$ : decreases

B. $CO(g)+3H_2(g)\rightarrow CH_4(g)+H_2(g)$ : decreases

C. $CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$ : no change

D. $N_2O_2(g)\rightarrow 2NO(g)+O_2(g)$ : increases

Explanation:

Entropy is defined as the randomness of the system.

Entropy is said to increase when the randomness of the system increase, is said to decrease when the randomness of the system decrease and is said to have no change when the randomness remains same.

In reaction $K(s)+O_2(g)\rightarrow KO_2(s)$ , as gaseous reactant is changed to solid product, entropy decreases.

In reaction $CO(g)+3H_2(g)\rightarrow CH_4(g)+H_2O(g)$ , as 4 moles of gaseous reactants is changed to 2 moles of gaseous product, entropy decreases.

In reaction $CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)$ , as 3 moles of gaseous reactants is changed to 3 moles of gaseous product, entropy has no change.

In reaction $N_2O_2(g)\rightarrow 2NO(g)+O_2(g)$ , as 1 mole of gaseous reactant is changed to 3 moles of gaseous product, entropy increases.
