Which property of isotopes makes them suitable for determining the dates of ancient artifacts? atomic number of the isotope rate of decay of the isotope radiation from the isotope stable nature of the isotope

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.

1. they vary with a higher number because boiling is way hotter than melting
