Answer:
2Al3+ + Fe2O3 -> Al2O3 + 2Fe3+
Explanation:
Educated Guess Here!
Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.
Benthos are "organisms inhabiting the seafloor" according to one source, so I would say the answer is C.
Given the volume of HCl solution = 30.00 mL
Molarity of HCl solution = 0.1000 M
Molarity, moles and volume are related by the equation:
Molarity = 
Converting volume of HCl from mL to L:

Calculating moles of HCl from volume in L and molarity:

The final moles would be reported to 4 sig figs. So the correct answer will be 0.03000 mol HCl
Correct option: C. 0.03000mol
