Answer:

V_2=10.8L

Explanation:

Hello,

In this case, we use the combined idea gas equation that help us to understand the volume-pressure-temperature relationship as:

\frac{P_1V_1}{T_1}= \frac{P_2V_2}{T_2}

So, we solve for the final volume as shown below, considering the given data at the beginning of the experiment:

V_2=\frac{P_1V_1T_2}{T_1P_2}=\frac{6.7atm*18L*250K}{500K*5.6atm}\\ \\V_2=10.8L

Best regards.

Answer:

10.77 L

Explanation:

Initial pressure P1= 6.7atm

Initial temperature T1= 500K

Initial volume V1= 18L

Final pressure P2= 5.6 atm

Final temperature T2= 250K

Final volume V2=???

From the general gas equation:

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2= 6.7×18×250/5.6×500= 30150/2800

V2= 10.77 L

Where do the protons and electrons come from that are used in the electron transport chain?
blondinia [14]
The energy generated by the movement of electrons is used to pump electrons across the inner mitochondrial membrane to an area of higher concentration. 17. Where do these protons (H+) come from? The originally came from a glucose molecule and were carried to the electron transport chain by NADH and FADH2.

The answer would be glucose molecule.
