Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical equation for it. Be sure your chemical equation is balanced and has physical state symbols.
1) A strip of solid iron metal is put into a beaker of 0.072M Cu(NO3)2 solution.
2) A strip of solid copper metal is put into a beaker of 0.081M FeSO4 solution.

1.Fe(s) + Cu(NO3)2(l) = Fe(NO3)2(l) +Cu(s) gibbs energy is negative hence reaction will move forward

Explanation:

Solid iron strip will react with Cu(NO3)2 solution but copper will not react with FeSO4 solution because gibbs energy of this reaction is positive and the reaction is only occur when gibbs energy is negative.

1.Fe(s) + Cu(NO3)2(l) = Fe(NO3)2(l) +Cu(s) gibbs energy is negative hence reaction will move forward

2.Cu(s) + FeSO4(l) = Fe(S) +CuSO4(s) gibbs energy is positive hence reaction will not occur

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.

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot
