Which of the following properly lists the metals in order from decreasing to increasing ease of oxidation? a. k < cu < cr < ag b. ag < cr < cu < k c. k < cr < cu < ag d. ag < cu < cr < k

in order from decreasing to increasing ease of oxidation

D. Ag < Cu < Cr < K

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.
