What happens hydrogen and carbon during combustion and what is formed as a result?
During combustion, hydrogen and carbon react with oxygen to form water and carbon dioxide. The hydrogen combines with oxygen to form water vapor (H2O), while carbon combines with oxygen to form carbon dioxide (CO2).
What happens during the combustion of hydrogen.?
During the combustion of hydrogen, hydrogen gas (H₂) reacts with oxygen (O₂) in the presence of heat to produce water (H₂O) as the primary product. This reaction releases a significant amount of energy in the form of heat and light, making it an exothermic process. The balanced chemical equation for this reaction is 2H₂ + O₂ → 2H₂O. Additionally, the combustion of hydrogen produces no carbon emissions, making it a clean energy source.
Why is water identical to the standard enthalpy change of combustion of hydrogen.?
Water is identical to the standard enthalpy change of combustion of hydrogen because the combustion of hydrogen involves its reaction with oxygen to form water. The standard enthalpy change of this reaction is defined by the energy released when hydrogen combusts completely, which results in the formation of water as a product. Thus, the formation of water from hydrogen and oxygen under standard conditions directly correlates to the enthalpy change associated with the combustion process. Hence, the enthalpy change for the formation of water from its elemental components is equivalent to the enthalpy change of hydrogen combustion.
What happens when a split that is on fire is placed into a container containing hydrogen gas and oxygen gas?
If a split that is on fire is placed into a container containing hydrogen gas and oxygen gas, the split will react with the hydrogen and oxygen gases causing a combustion reaction. This reaction will produce water vapor and release a large amount of heat and light. It can result in an explosion due to the rapid combustion of hydrogen and oxygen.
What is a necessary product in a combustion reaction?
A necessary product in a combustion reaction is carbon dioxide (CO₂). During combustion, a fuel (typically containing carbon and hydrogen) reacts with oxygen (O₂) to produce energy, water (H₂O), and carbon dioxide if the combustion is complete. Incomplete combustion can also produce carbon monoxide (CO) and other byproducts, but CO₂ is a key indicator of complete combustion.
What happens hydrogen and carbon during combustion and what is formed as a result?
During combustion, hydrogen and carbon react with oxygen to form water and carbon dioxide. The hydrogen combines with oxygen to form water vapor (H2O), while carbon combines with oxygen to form carbon dioxide (CO2).

Is the combustion of hydrogen exothermic or endothermic?
The combustion of hydrogen is exothermic because it releases energy in the form of heat and light during the reaction.
Which element is required for the combustion of fossil fuels?
Oxygen is required for the combustion of fossil fuels. During combustion, the carbon and hydrogen in the fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
How does the reaction of hydrogen and oxygen to produce energy in a fuel cell differ from their interaction during the direct combustion of hydrogen and oxygen?
In a fuel cell, the reaction of hydrogen and oxygen occurs electrochemically, producing electricity as a byproduct. This process is more efficient and produces less waste compared to direct combustion of hydrogen and oxygen, which releases energy in the form of heat without generating electricity. Fuel cells offer a cleaner and more controlled way to harness energy from hydrogen compared to combustion.
Can a combustion reaction produce hydrogen?
No. If anything, a combustion reaction will consume hydrogen.
What gas is given off during combustion that puts out flames?
hydrogen ------- During the burning of organic materials carbon dioxide is released.
Does hydrogen support combustion?
Yes, hydrogen is highly flammable and supports combustion. When hydrogen comes into contact with oxygen, it ignites and produces a flame.
How do motors on hydrogen cars differ from combustion or hybrid engines?
Like a gas combustion engine, a hydrogen engine relies on the combustion process - in this case, combustion that results when hydrogen is combined with oxygen. Fuel cells in a hydrogen-powered car then convert this mechanical energy into electrical energy.
Can hydrogen support combustion?
Hydrogen is a fuel for combustion, but cannot support it in the manner than oxygen can.
Hydrogen in internal-combustion engine?
no
What is the equation for the incomplete combustion of hydrogen?
The equation for the incomplete combustion of hydrogen is 2H₂ + O₂ -> 2H₂O + energy (incomplete combustion).
