Research and development efforts are ongoing to overcome these challenges and make hydrogen a viable and sustainable energy option.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><b><span data-contrast=\"none\">6:<\/span><\/b><span data-contrast=\"none\"> Why is hydrogen written as H<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\">?<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">6: Hydrogen is written as H<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\"> to indicate that it exists as a diatomic molecule. In its gaseous form, hydrogen atoms tend to bond together to form stable H<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\"> molecules. Each hydrogen molecule consists of two hydrogen atoms that are covalently bonded, sharing a pair of electrons. By representing hydrogen as H<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\">, it reflects the fact that it naturally occurs as a molecule with two hydrogen atoms bonded together.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">7: How is hydrogen gas made?<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">Answer: Hydrogen gas can be made through various methods.

It is a colorless and odorless gas. At room temperature and atmospheric pressure, hydrogen exists as a diatomic molecule (H<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\">), meaning two hydrogen atoms are bonded together. Hydrogen gas has a very low density and is highly flammable.
