The chemical equation you provided, NaOC3H7 + SCO3H4, is not a balanced equation and appears to be missing the reaction arrow. It also seems to have a typo in the second compound.
However, it seems you are trying to express a chemical reaction involving sodium propoxide (NaOC3H7) and acetic acid (CH3COOH). When these two compounds react, they form sodium acetate (NaCH3COO) and ethanol (C2H5OH). The balanced chemical equation for this reaction is:
2CH3COOH + 2NaOC3H7 → 2NaCH3COO + C2H5OH
In this reaction, the sodium propoxide (NaOC3H7) reacts with acetic acid (CH3COOH) to produce sodium acetate (NaCH3COO) and ethanol (C2H5OH). This is a type of esterification reaction.
