Chapter EH, Problem 3R

Solution

Interpretation: To know what happens when hydrogen reacts with non-metal elements.

Concept Introduction: Non-metal can be known as elements that have the ability to gain an electron from other elements and form an anion. P-block elements are generally considered non-metals.

When non-metals react with hydrogen ${\text{(H}}_{\text{2}}\text{)}$ then will form covalent hydrides.

When hydrogen will react with non-metals then it will form covalent hydrides. Its reaction can be expressed as:

When hydrogen will react with sulfur then it will form hydrogen sulfide.

  ${\text{H}}_{\text{2}}\text{+S}\to {\text{H}}_{\text{2}}\text{S}$ .

When hydrogen will react with nitrogen (non-metal), then it will form ammonia.

  ${\text{N}}_{\text{2}}{\text{(g)+3H}}_{\text{2}}\text{(g)}\to 2{\text{NH}}_{\text{3}}\text{(g)}$
