Answer:

Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂ (s)

Step-by-step explanation:

The reaction of the formation of Ca(NO₃)₂(s) , is as follows -

Ca + N₂ + O₂ → Ca(NO₃)₂

The above reaction , can be balanced by adding whole numbers ,

Hence , the balanced reaction is as follows -

Ca + N₂ + 3O₂ → Ca(NO₃)₂

The states of the respective molecules is -

the state at which the atoms are most stable or the state at which the atoms are most commonly found .

Hence ,

Calcium is most stable in solid state

Oxygen is most stable in gaseous state

Nitrogen is most stable in gaseous state

hence , the balanced reaction with all the states mentioned is as follows -

Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂ (s) .
