No! That’s why they’re called theories. Most of them have a lot of facts to back it up however the theories themselves are either proven or just hypothetical.

How many grams of solid Ca(OH)2 (74.1 g/mol) are required to make 500 ml of a 3 M solution?
mars1129 [50]

Answer:

111.15 g are required to prepare 500 ml of a 3 M solution

Explanation:

In a 3 M solution of Ca(OH)₂ there are 3 moles of Ca(OH)₂ per liter solution. In 500 ml of this solution, there will be (3 mol/2) 1.5 mol Ca(OH)₂.

Since 1 mol of Ca(OH)₂ has a mass of 74.1 g, 1.5 mol will have a mass of

(1.5 mol Ca(OH)₂ *(74.1 g / 1 mol)) 111.15 g. This mass of Ca(OH)₂ is required to prepare the 500 ml 3 M solution.

El método de cristalización sirve para separar agua salada y obtener ambos componentes por separado
GaryK [48]

Answer:

Si.

Explicación:

Sí, el método de cristalización se utiliza para separar la sal del agua y obtener los componentes de la sal y del agua por separado. La cristalización es un método o técnica que se utiliza para purificar compuestos sólidos. Este proceso funciona mejor debido a las diferentes solubilidades del compuesto deseado y las impurezas que están presentes en un solvente dado. El proceso de cristalización implica enfriar agua salada para formar cristales de hielo puro. Luego, los cristales de hielo se separan de la salmuera no congelada, se lavan para eliminar la sal residual y luego se derrite la solución para producir agua dulce.
