Chemistry homework chemical equations

2 C2H6 + 7O2 => 6 H2O + 4 CO2

12HClO4 + P4O10 => 4 H3PO4 + 6Cl2O7

2 N2 + 5 O2 + 2 H2O => 4 HNO3

3 CaCl2 + 2 Na3PO4 => 1 Ca3(PO4)3 + 6 NaCl

4 FeS + 7 O2 => 2 Fe2O3 + 4 SO2

Explanation: Each equation is now balanced both in the reactant and product side.

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.
