Chemical equation and reaction
WebChemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H 2) can react (burn) with oxygen gas (O 2) to form water (H 2 O). The chemical equation for this reaction is written as: 2H2 + O2 → 2H2O WebOct 7, 2024 · Because these reactions are typically associated with high forces (approximately nanonewtons), the amount of energy absorbed at the single-molecular level can be quite large relative to the energy absorbed by a covalent strand in the absence of the reaction-enabled extension ( 8 ).
