. Supongamos que una cucharadita de bicarbonato (NaHCO3) pesa aproximadamente 7 g, que el vinagre es 100% ácido acético (CH3COOH) y que una cucharadita pesa aproximadamente 5 g. ¿Qué cantidad de dióxido de carbono (CO2) se produce al mezclar una cucharadita de cada reactivo? Utiliza la relación estequiométrica de la ecuación química. NaHCO3(s) + CH3COOH(l) → CH3COONa(l) +CO2(g) +H2O(l)

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
