The number of moles of aluminium  that are needed to react completely  with 13.2 moles of FeO  is  8.8 moles



calculation


2Al + 3FeO → 3aFe +Al2O3

by use of of mole ratio of Al: FeO  from  equation above = 2:3 the moles of  Al is  therefore

= 13.2  x  2/3=8.8  moles  of Al

5. Which type of substance yields hydrogen ions, H+, in
GaryK [48]

Answer: An Arrhenius acid is a type of substance yields hydrogen ions, H^{+}, in an aqueous solution.

Explanation:

Substances that give dissociate to give hydrogen ions or protons when dissolved in an aqueous solution are called Arrhenius acid.

For example, HCl is a strong acid and upon dissociation in water it gives the following ions.

HCl \rightarrow H^{+} + Cl^{-}

Thus, we can conclude that an Arrhenius acid is a type of substance yields hydrogen ions, H^{+}, in an aqueous solution.

natulia [17]

Answer:

1.52V

Explanation:

Oxidation half equation:

2Al(s)−→2Al^3+(aq) + 6e

Reduction half equation

3Sn2^+(aq) + 6e−→3Sn(s)

E°cell= E°cathode - E°anode

E°cathode= −0.140 V

E°anode= −1.66 V

E°cell=-0.140-(-1.66)

E°cell= 1.52V
