Enter the chemical equation for the formation of Ca (NO3) 2 (s) from its respective elements in their standard states.

Express your answer as a chemical equation.

Identify all of the phases in your answer.

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

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).
