Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
Answer;
-Aerobic respiration;
Explanation;
-Aerobic respiration is the process in living things that evolved as oxygen levels increased in earth's atmosphere. Aerobic respiration is the process in which cellular energy is produced in the presence of oxygen. Cells breakdown nutrients, such as glucose, in the mitochondria to produce energy in the form of ATP which can be used by the cells.
Answer:
-484kJ
Explanation:
Carry out bond energy calculation
[6(C-H) + (C=O) +2(C-C)] - [(O-H) +7(C-H)+ (C-O) +2(C-C)]
Substitute the bond energy values = -484kJ
