It is Exothermic Change because,Exothermic is a chemical reaction that releases energy it could be light or heat. :)
Answer:
During the uncoupling of electron transport chain energy that is generated by the transport of electron along with proton, is released as heat.
Explanation:
The proton motive force generate energy for the phosphorylation of ADP with inorganic phosphate to form ATP an energy rich molecule during the process called oxidative phosphorylation.
There are some chemical agents knowns as uncouplers for examole thermogennin,2'4-dinitophenyl.They does not interfere with the transport of electrons through various electron carriers which generate energy,but uncouplers blocks the phosphorylation step.
As a result the energy that is released during transport of electron, is liberated as heat.
The answer is B, the number of protons

Answer:
16.98 g
Explanation:
The balacend equation is
Fe2O3(s) + 2Al(s) → 2Fe(l) + Al2O3(s)
So, when 2 moles of iron (Fe) are produced, 1 mol of aluminum oxide is produced. The mass molar of the elements are:
Fe = 56 g/mol; O = 16 g/mol; Al = 27 g/mol
Then, the mass molar of Al2O3 is:
2x27 + 3x16 = 102 g/mol
The stoichiometry relation will be:
2 mol of Fe -------------------- 1 mol of Al2O3
2x56 g of Fe -------------------- 102 g of Al2O3
18.65 g of Fe -------------------- x g of Al2O3
By a direct simple three rule:
112x = 1902.3
x = 16.98 g
