Each 100 cm3 of air, constitutes 78cm3 nitrogen, 21cm3 oxygen and 1cm3 constitutes of other gases like Argon, ozone, carbon dioxide and water vapour in small amounts.
The equation that correctly represent the reaction for formation of ammonia is
N2+ 3H2 → 2NH3 (answer D)
1 mole of nitrogen gas (N2) react with 3 moles of hydrogen gas (H2) to form 2 moles of ammonia ( NH3). This is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. The process is exothermic hence energy is released.
A. because the wax was hot meaning it’s molecules are moving fast and then cooling down which slows down the molecules. this is the same thing that happens when water changes it’s state to ice
I think it might be nitride
