Which of the following represents a decomposition reaction? A. AC + B → AB + C B. A + B + C → ABC C. ABC → A + B + C D. AB + CD → AC + BD

b. atoms in metallic solids are not arranged in a regular pattern

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.
