La soda para lavar, un compuesto que se usa para preparar agua dura para lavar la ropa, es un hidrato. Su fórmula se puede escribir como Na, CO, • xH, O, donde x es el número de moles de mol de Na, CO3. Cuando una muestra de 2.558 g de sosa de lavado se calienta a 25 ° C, se pierde toda el agua de hidratación, dejando 0.948 g de Na, COg. ¿Cual es el valor de x?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
