(a)
Interpretation: 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
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.
(b)
Interpretation: The balanced chemical equation should be written for the reaction of hydrogen gas with chlorine.
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
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.
(c)
Interpretation: The balanced chemical equation should be written for the reaction of hydrogen gas with nitrogen.
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
