Answer:

Requiere que el agua pase por membranas de filtración.

Explanation:

Un purificador de agua que utiliza energía solar es un dispositivo innovador y tecnológico que funciona como una estación de saneamiento básico con capacidad para purificar el agua y eliminar el 99% de virus y bacterias.

El sistema funciona de la siguiente manera: cuenta con bomba, panel solar, cargador y mangueras. La bomba mueve el agua a través del filtro utilizando la energía de la batería que se carga con la energía de la luz solar. Incluso en días con poca exposición al sol, el sistema es capaz de utilizar la energía acumulada de la batería y purificar 1 litro de agua en 1 minuto.

Se trata de una tecnología simple e innovadora que puede ser de gran ayuda en el saneamiento básico de lugares que no contienen agua potable, debido a la facilidad y portabilidad del sistema.

Given 3.4 grams of x compound with a molar mass of 85 g and 4.2 grams of y compound with a molar mass of 48 g How much of compou

Ulleksa [173]

Answer:

$4.36~g~XY$

Explanation:

In this case, we can start with the reaction:

$2X + Y_2~->~2XY$

If we check the reaction, we will have 2 X and Y atoms on both sides. So, the reaction is balanced. Now, the problem give to us two amounts of reagents. Therefore, we have to find the limiting reagent. The first step then is to find the moles of each compound using the molar mass:

$3.4~g~X\frac{1~mol~X}{85~g~X}=0.04~mol~X$

$4.2~g~Y_2\frac{1~mol~Y_2}{48~g~Y_2}=0.0875~mol~Y_2$

Now, we can divide by the coefficient of each compound (given by the balanced reaction):

$\frac{0.04~mol~X}{1}=~0.04$

$\frac{0.0875~mol~Y_2}{2}=0.04375$

The smallest value is for "X", therefore this is our limiting reagent. Now, if we use the molar ratio between "X" and "XY" we can calculate the moles of XY, so:

$0.04~mol~X\frac{2~mol~XY}{2~mol~X}=0.04~mol~XY$

Finally, with the molar mass of "XY" we can calculate the grams. Now, we know that 1 mol X = 85 g X and 1 mol $Y_2$ = 48 g $Y_2$ (therefore 1 mol Y = 24 g Y). With this in mind the molar mass of XY would be 85+24 = 109 g/mol. With this in mind:
