Answer:
-730KJ
Explanation:
According to the first law of thermodynamics;
Let the total energy of the system be ∆E
Let heat be q and let work the w
Since the energy decreases ∆E is negative
Since work is done on the system w= positive
So;
- 250 = 480 + q
q = -250 - 480
q=-730KJ
Answer:
1.Oxidation - reduction reactions and proton pumping
2. Phosphorylation reactions and proton pumping
Explanation:
In oxidative phosphorylation, electrons are transferred from donors to acceptors, that is redox reaction.
These redox reactions release energy, which is used to form ATP. In eukaryotes, these redox reactions are carried out by protein complexes within cell's mitochondria, whereas, in prokaryotes, these proteins are located in the cells' intermembrane space. These linked sets of proteins are called electron transport chains.
Answer:
Gas Giant- atmosphere primarily made of hydrogen and helium
Asteroid-varies greatly in size from one to the next
Comet-has a characteristic glow
Meteoroid-usually burns up if it enters Earth's
Explanation:
One formula unit of sodium chloride contains an ionic bond. The sodium loses an electron to become positively charged, the chlorine atom accepts the electron to become negatively charged, and the two oppositely charged ions attract each other. This electrostatic force of attraction is called an ionic bond.
