If you have ever seen hydrogen combine with oxygen directly you will remember that an explosion was involved. In classroom situations the amounts of the two gases used are very tiny and the explosion is safe but violent reactions like this cannot be allowed in a living cell. The other thing to note is that it was necessary to use a spark to set off the explosion. Again, this would not be possible in a living organism. All of the reactions in a cell have to be done in such a way as to cause no damage. Hence, the need for several steps.

I almost forgot: when the reaction between hydrogen and oxygen occurs if the energy provided is needed by the cell (or even if it isn't) the cell must have a way of capturing it in a useful form. There would be no point in releasing energy and allowing it to go to waste.

How do hydrogen peroxide redox reactions occur and what are their implications in chemical processes?

Hydrogen peroxide redox reactions happen when hydrogen peroxide (H2O2) is broken down into water (H2O) and oxygen (O2) through the transfer of electrons. These reactions are important in chemical processes as they can be used to disinfect, bleach, and oxidize substances. The release of oxygen gas can also be useful in various industrial applications.


What order are redox reactions balanced?

Atoms, O and H, then charge


How can one balance redox reactions in acidic solutions effectively?

To balance redox reactions in acidic solutions effectively, follow these steps: Write the unbalanced equation for the redox reaction. Separate the reaction into half-reactions for oxidation and reduction. Balance the atoms in each half-reaction, excluding oxygen and hydrogen. Balance the oxygen atoms by adding water molecules. Balance the hydrogen atoms by adding H ions. Balance the charges by adding electrons to one or both half-reactions. Ensure that the total charge and number of atoms are balanced in both half-reactions. Multiply each half-reaction by a factor to equalize the number of electrons transferred. Combine the balanced half-reactions to form the overall balanced redox reaction. By following these steps, one can effectively balance redox reactions in acidic solutions.


Which statemment is not true of most cellular redox reactions?

One statement that is not true of most cellular redox reactions is that they only involve the transfer of electrons between molecules. In some cases, redox reactions in cells may involve the transfer of hydrogen atoms or protons as well.


Which two reactions are also redox reactions combustion and single-replacement combustion and synthesis synthesis and decomposition single-replacement and double-replacement?

Combustion and single-replacement reactions are also redox reactions. In a combustion reaction, a substance combines with oxygen and releases energy. In a single-replacement reaction, one element replaces another in a compound, resulting in a change in oxidation states.

Why does it take several redox reaction in a cell to make water from hydrogen and oxygen?

Without getting into the specifics of the electron transport chain, redox reactions are needed because electrons need to be shuffled around to provide the right conditions for the oxygen and hydrogen to combine. After respiration, there are many hydrogen ions (protons) sitting around while "their" electrons are being passed back and forth in continuous redox reactions. The very last redox reaction is when the electronegative oxygen accepts the electrons -- then four hydrogen ions come in to bond with O2 to make two water molecules.
