Tony recorded data from his chemistry experiment in the following table. sample color volume temperature mass a yellow 150 ml 20°c 40.1 g b red 125 ml 20°c 15.2 g c clear 175 ml 20°c 26.3 g d green 150 ml 20°c 81.4 g which of the categories from tony's data table includes qualitative observations? a. mass b. temperature c. color d. volume

I think the qualitive observation is the color

Explanation:

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.
