Uno de los componentes del “sal de uvas”, es el bicarbonato de sodio, es un sólido cristalino blanco, debido a su capacidad de neutralizar el exceso de ácido clorhídrico del estómago.

La acidez estomacal es ocasionada por un exceso en la producción de ácido clorhídrico (HCl) en el jugo gástrico del estómago. Uno de los componentes del “sal de uvas”, utilizada como antiácido, es el bicarbonato de sodio (NaHCO₃), es un sólido cristalino blanco, que neutraliza el exceso de ácido clorhídrico. La reacción de neutralización es:

HCl(aq) + NaHCO₃(aq) ⇒ NaCl(aq) + H₂O(l) + CO₂(g)

Uno de los componentes del “sal de uvas”, es el bicarbonato de sodio, es un sólido cristalino blanco, debido a su capacidad de neutralizar el exceso de ácido clorhídrico del estómago.

A 4.86-gram sample of calcium reacted completely with oxygen to form 6.80 grams of calcium oxide. This reaction is represented b
sesenic [268]
The number of mole of Ca reacted is:
4.86 g Ca/ (40.08 g/mol Ca)= 0.121 mol Ca

Because Ca reacted completely with oxygen and there is 2 mol Ca, there is 1 mol O2 reacted.

Total mass of oxygen that reacted is:
0.121 mol Ca* (1mol O2/ 2 mol Ca)* (32 g O2/ 1 mol O2)= 1.94 g O2 reacted.

Hope this would help~
