Hydrogen and oxygen with ignition

Relationship

What connects the input and output?

Ignition supplies activation energy so hydrogen and oxygen bonds can break and rearrange into water. The balanced coefficients conserve every atom and set a 1:1 molar ratio between hydrogen and water. Use the calculator to scale the balanced molar relationship to any amount of H2.
