lutik1710 [3]

Answer:

C) H⁺

Explanation:

When we are balancing the reaction<em> in an acid medium</em>, hydrogen is balanced using the <u>H⁺</u> species. This is most likely the intended answer of your question.

When the reaction takes place not in an acid medium, but in <em>an alkaline one</em>, then hydrogen is present as the OH⁻ species. However this option is not given in your question.

Thus the answer is option C).

I believe that it is all of the above.

"A Scientific Hypothesis Must Be "Falsifiable". A scientific hypothesis must be testable, but there is a much stronger requirement that a testable hypothesis must meet before it can really be considered scientific."

I hope this helped, have a nice day!

Write a chemical equation for NH4+(aq) showing how it is an acid or a base according to the Arrhenius definition. Express your a
Galina-37 [17]

Answer:

NH4+(aq)  → NH3(aq) + H+(aq)

Explanation:

Following arrhenius, an acid can be defined as:

An Arrhenius acid is a substance that, when added to water, increases the concentration of H+ ions in water.

NH4+(aq)  → NH3(aq) + H+(aq)

The ammonium ion acts as a weak acid in aqueous solution, dissociating into ammonia and a hydrogen ion.

An Arrhenius base is a substance that, when added to water, increases the concentration of OH- ions in water.

NH4+(aq) will not dissciate in OH- ions. So it's not a base, but an acid.
