Answer:
The initial temperature is 300 K (The temperature doesn't change)
Explanation:
Step 1: Data given
Initial volume = 21L
Final volume = 14L
Initial pressure = 100 kPa = 0.986923 atm
Final pressure = 150 kPa = 1.48038 atm
The final temperature = 300K
Step 2: Calculate the initial temperature
Calculate the initial temperature
(P1*V1)/T1 = (P2*V2)/T2
⇒with P1 = the initial pressure = 0.986923 atm
⇒with V1 = the initial volume = 21 L
⇒ with T1 = the initial temperature = ?
⇒with P2 = the final pressure = 1.48038 atm
⇒with V2 = the final volume = 14 L
⇒with T2 = the final temperature = 300 K
(0.986923 * 21)/T1 = (1.48038*14)/300
T1 = 300 K
The initial temperature is 300 K (The temperature doesn't change)
If the change in Gibbs free energy for a process is positive, the corresponding change in entropy for the universe will be positive.
<h3>What is Gibbs free energy?</h3>
This is defined as the energy used by a substance involved in a chemical reaction.
The Gibbs free energy and entropy has a direct relationship which is why a positive gibbs free energy will result in a corresponding positive entropy.

Then I would guess the answer is D because Na2OH is much more common and stable than Na2O is <span />
Answer:
never gonna give you up never gonna let you down NEVER GONNA RUN AROUND AND DESSERT YOUUUUUUUUUUUU
Explanation:
Answer:
neither photosynthesis nor respiration.
Explanation:
Photosynthesis is the process by which the green plants, in the presence of sunlight makes their own food. In the process carbon dioxide is absorbed and oxygen is released.
Respiration is the intake of oxygen and the metabolism of the glucose in which it is breakdown and releases carbon dioxide.
In neither of the two processes, carbon dioxide is splitted.
