In a hydrogen fuel cell, hydrogen gas (H₂) reacts with oxygen gas (O₂) to produce water (H₂O) and electricity. The reaction occurs at the anode, where hydrogen molecules are split into protons and electrons. The protons move through the electrolyte to the cathode, while the electrons flow through an external circuit, generating electricity. At the cathode, the protons, electrons, and oxygen combine to form water, completing the reaction.

Which type if of chemical reaction takes place when hydrogen peroxide is heated and separates into hydrogen and oxygen?
The decomposition reaction occurs when hydrogen peroxide is heated and breaks down into hydrogen and oxygen. This is because the heat provides the activation energy needed for the chemical bonds in hydrogen peroxide to be broken, resulting in the formation of hydrogen and oxygen gases.
The Factors that could have influenced the rating of the chemical reaction between the liver and the hydrogen peroxide is?
Factors that could influence the rating of the chemical reaction between liver and hydrogen peroxide include the concentration of hydrogen peroxide used, the temperature at which the reaction occurs, the pH of the solution, and the amount of liver tissue present. Additionally, the presence of any catalysts or inhibitors in the reaction mixture could also impact the rating of the reaction.
What do you call it when elements combine to form new substances?
im pretty sure a chemical reaction occurs then an compound is made
How does a chemical reaction happen when a balloon burst?
When a balloon bursts, the chemical reaction that occurs is a rapid release of the gas inside the balloon. This is due to the sudden increase in pressure inside the balloon, causing it to exceed the strength of the balloon material and burst. The gas molecules escape quickly into the surrounding environment, resulting in a popping sound and the sudden deflation of the balloon.
What type of chemical reaction occurs when a disposable lighter is used?
What is the chemical reaction of a dispoiable lighter
What happens when you add hydrogen to iodine?
When hydrogen gas is added to iodine, a chemical reaction occurs that forms hydrogen iodide (HI) gas. The reaction is exothermic, meaning it releases heat energy. This reaction is represented by the chemical equation: H2 + I2 -> 2HI.
When a chemical reaction between oxygen and hydrogen gas occurs what happens?
water is formed H2O (2 hydrogen 1 oxygen)
When a chemical reaction between oxygen gas and hydrogen gas occurs?
water is formed H2O (2 hydrogen 1 oxygen)
What type of chemical reaction occurs when Hydrogen peroxide break apart to form water and oxygen gasthings happen?
This is a chemical reaction because it is not possible to rearrange water and oxygen to form hydrogen peroxide after they are split apart (in other words after the chemical reaction has occurred. (And this was also part of the question in my homework so to make it easier Hydrogen peroxide is the reactant, and oxygen and hydrogen are the products.)
What do you think will happen when an acid and metal come in contact with each other?
When an acid and metal come in contact, a chemical reaction occurs where the metal will dissolve and release hydrogen gas. This reaction is known as a single displacement reaction, where the metal displaces hydrogen from the acid.
Which type if of chemical reaction takes place when hydrogen peroxide is heated and separates into hydrogen and oxygen?
The decomposition reaction occurs when hydrogen peroxide is heated and breaks down into hydrogen and oxygen. This is because the heat provides the activation energy needed for the chemical bonds in hydrogen peroxide to be broken, resulting in the formation of hydrogen and oxygen gases.
What chemical reaction occurs when oxygen gas is combined with hydrogen gas?
Two reactions are possible 2H2 + O2 -> 2H2O - complete combustion to form water H2 +O2 -> H2O2 -incomplete combustion to form hydrogen peroxide
Does hydrogen sulfide react with aluminum?
Yes, hydrogen sulfide can react with aluminum to form aluminum sulfide. This reaction typically occurs when hydrogen sulfide gas comes into contact with aluminum metal, initiating a chemical reaction that produces aluminum sulfide and hydrogen gas.
The Factors that could have influenced the rating of the chemical reaction between the liver and the hydrogen peroxide is?
Factors that could influence the rating of the chemical reaction between liver and hydrogen peroxide include the concentration of hydrogen peroxide used, the temperature at which the reaction occurs, the pH of the solution, and the amount of liver tissue present. Additionally, the presence of any catalysts or inhibitors in the reaction mixture could also impact the rating of the reaction.
What happens when you mix sodium with hydrogen chloride?
When sodium is mixed with hydrogen chloride, a chemical reaction occurs where the sodium displaces hydrogen to form sodium chloride (table salt) and hydrogen gas. The reaction is highly exothermic and can be dangerous if not conducted properly, as it produces heat and releases flammable hydrogen gas.
If five atoms of hydrogen are reactants in a chemical reaction then how many atoms of hydrogen will be found in the products of that reaction?
If five atoms of hydrogen are reactants in a chemical reaction, typically all five atoms will be found in the products unless some sort of splitting or rearrangement of atoms occurs during the reaction. It follows the principle of conservation of mass, meaning atoms cannot be created or destroyed in a chemical reaction.
When aluminum metal is added to hydrobromic acid what kind of change occurs?
A chemical change occurs when aluminum metal is added to hydrobromic acid. This reaction produces aluminum bromide and hydrogen gas as products. The aluminum metal reacts with the hydrobromic acid to form aluminum bromide and hydrogen gas, which is a common example of a single replacement reaction.
