Maksim231197 [3]3 years ago
4 0
Fuel cells work by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. On the anode site, hydrogen molecules are split into electrons and protons. They have a high efficiency therefore these fuel cells are also considered to be very clean plus a fuel cells only by-products are electricity, excess heat, and water.

Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water.
Marrrta [24]

Hello, this question is incomplete. The complete question would be:

"Write the balanced chemical equation for the following reaction.

Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water"

Answer:

Fe2O3 + 3 H2 = 2 Fe + 3 H2O

Explanation:

In a chemical reaction, the structure of atoms as chemical elements is unchanged. Atoms in one element do not become atoms in another element. There is also no loss or creation of new atoms. The number of atoms of the reagents must be equal to the number of atoms of the products. When this happens, we say that the chemical equation is balanced.

For this reason, we can state that the balanced chemical reaction where solid iron (III) oxide reacts with hydrogen gas to form solid iron and liquid water would be:

<em>Fe2O3 + 3 H2 = 2 Fe + 3 H2O </em>

What is the outcome of ketosis? glycogen buildup metabolic alkalosis water retention and edema glucogenesis
blsea [12.9K]

<u>Metabolic acidosis</u> would be the result of ketosis. A buildup of ketones in the body that is too great leads to metabolic acidosis.

An excess of acids in the blood can lead to metabolic acidosis. When our kidneys find it difficult to sufficiently eliminate acid from human blood, this occurs.

Because there is an excessive amount of ketone bodies in the blood, ketoacidosis would be a metabolic acidosis with a significant anion gap (keto-anions). The liver releases ketone bodies (acetoacetate, beta-hydroxybutyrate, and acetone) into the blood when the state of the liver's lipid metabolism shifts to one of greater ketogenesis.

In addition to assisting with fat loss, ketosis can reduce your appetite. It also aids in maintaining muscle. Ketosis typically begins to occur in healthy individuals who do not have diabetes and are not pregnant after 3 to 4 days of consuming just under 50 grams of carbohydrates each day.

Therefore, the outcome of ketosis will be <u>Metabolic acidosis</u>
