Hemoglobin in your blood does not use elemental iron. it uses iron in the form of fe2+(aq).

iron reacts with acid (represented as h+(aq)) to produce fe2+(aq) and hydrogen gas.

write a balanced chemical reaction, including phase symbols, to describe the reaction of iron with acid.

write a hypothesis that may explain how and where neutral iron is converted to fe2+ cation in the human body.

Explanation:

Balanced chemical reaction equation will be as follows.

In human body, the neutral iron changes into (aq) cation. There will be an oxidation-half reaction and a reduction-half reaction. Equations for this reaction are as follows.

Oxidation: 2Fe^{2+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + 2e^{-}[/tex] .... (1)

Reduction: ...... (2)

On adding both equation (1) and (2), the overall reaction equation will be as follows.

Therefore, neutral iron is a part of Heme - b group of Hemoglobin and in an aqueous solution it dissolutes as a part of Heme group. Hence, then it becomes an cation.

what are the two models

explanation:

"the periodic table is arranged in order of atomic number."
