In the reaction of hydrogen gas and oxygen gas to form water, the glowing splint is a test used to indicate the presence of oxygen, but it is not a reactant or product of the chemical reaction itself. Instead, it is commonly used to demonstrate the presence of oxygen gas because a glowing splint will re-ignite in an oxygen-rich environment.
To clarify, here are the correct matches based on the options given:
- Is one of the reactants of the reaction: False (The reactants are hydrogen gas and oxygen gas.)
- Provides the kinetic energy for the reaction: False (The kinetic energy comes from the collision of molecules, not from the glowing splint.)
- Provides the activation energy for the reaction: False (Activation energy is the energy required to initiate a reaction and is not provided by the glowing splint.)
- Is one of the products of the reaction: False (The products are water, not the glowing splint.)
The glowing splint itself does not fit into any of those categories directly. It's a tool for testing but does not affect the reaction's energy or output directly.
