The balanced chemical equation should be written for the reaction of hydrogen gas with oxygen. Concept introduction: The reaction of elements with hydrogen produces either ionic metal hydrides or molecular compounds. The reaction of hydrogen with metals produces ionic metal hydrides. The electronegativity of hydrogen is more than metals and hence, metals bear positive charge and hydrogen has a negative charge. Thus, the oxidation number of hydrogen in ionic metal hydrides is − 1 . The reaction of non-metals with hydrogen produces molecular compounds. In general, non-metals are more electronegative than hydrogen and hence, hydrogen bears positive charge and non-metals are negatively charged in molecular compounds. Thus, the oxidation number of hydrogen in molecular compounds is + 1 . The oxidation number of metals in ionic hydrides and non-metals in molecular compounds are according to the group number and valence electron configuration of these elements. So, hydrogen reacts with both metals and non-metals to produce hydrides of corresponding elements. However, the elements belonging to the noble gas family have very low chemical reactivity and therefore do not combine with hydrogen.

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
