Explain how to make 1 liter of a 0.45 M solution of K 2 S O 4 K2SO4 using K 2 S O 4 K2SO4 powder and water.

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.

1.solid

2.carbon dioxide

3.helium

answer carbon and three oxygen atoms;
