What is the balanced chemical equation for the reaction used to calculate ΔH∘f of SrCO3(s)?

If fractional coefficients are required, enter them as a fraction (i.e. 1/3). Indicate the physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively without indicating allotropes. Use (aq) for aqueous solution.

Answer :

Standard enthalpy of formation : It is defined as the enthalpy change for the reaction that forms one mole of compound from its elements. All the substances in their standard states.

The balanced chemical equation for the reaction is,

[tex]Sr(s)+C(s)+\frac{3}{2}O_2(g)\rightarrow SrCO_3(s)[/tex]

In the balance reaction, Strontium (Sr), Carbon (C) and Strontium carbonate [tex]SrCO_3[/tex] are in solid state and oxygen is in gaseous state.
