Answer:

$\%Ca=19.378\%$

Explanation:

¡Hola!

En este caso, basado en la información dada, es posible conocer la masa de calcio en carbonato de calcio, que de hecho es la misma en la muestra, al utilizar el siguiente esquema de cálculo:

$m_{Ca}=1,2093gCaCO_3*\frac{1molCaCO_3}{100.1gCaCO_3}*\frac{1molCa}{1molCaCO_3}*\frac{40.1gCa}{1molCa}\\\\m_{Ca}=0.48444gCa$

Finalmente, calculamos el porcentaje requerido como sigue:

$\% Ca=\frac{0.48444g}{2.5000g} *100\%\\\\\%Ca=19.378\%$

¡Saludos!

In its aqueous solution, 32% of a substance dissociates to release hydroxide ions. Which of the following is true for the substa

Scrat [10]

The solution is a weak base. a weak base is that which dissociates partially in aqueous solution to give hydroxide ions as the only negatively charged ions. In the provided information, only 32 %of the substance dissociates thus it is a partial dissociation. Most of the energy is used to break bonds thus the remaining energy is not enough to cause complete dissociation.
