In your own words, explain the Law of Conservation of Mass.

Here's my definition (in my own words)

Explanation:

In any closed system... no matter what reactions occur, the mass of the system will remain the same. Mass will not be destroyed, rather it will just be "converted" to something else.

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.

its going to be mutualism cuz they both benefit from the relationship.
