Solid silver is added to copper (ii) sulfate. does a single replacement reaction occur, and if so what is the correct chemical equation for this reaction? 2ag + cuso4 yields no reaction ag + cuso4 yields agso4 + cu ag + cuso4 yields ag2so4 + cu 2ag + cuso4 yields ag2so4 + cu

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.
