2. When the reaction below is balanced with the smallest possible whole number coefficients, what is the coefficient in front of lithium nitrate, LiNO3? Li3PO4 + Ca(NO3)2 → LINO3 + Ca3(PO4)2 a. 2 b. 3 C. 4 d. 6

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.
