El agua se purifica a partir de un proceso de filtrado. Las características que evidencian el filtrado incluyen pH normal, color cristalino, ausencia de metales pesados y/o microorganismos, etc.

  • Los filtros para purificar agua son dispositivos que permiten el limpiado del agua con el objetivo de convertirla apta para consumo humano.

  • En general, los filtros para lograr la purificación del agua consisten de carbón activado, el cual se prensa con alta presión.

  • Este dispositivo de carbón activado permite secuestrar las partículas sólidas que pasan a través del filtro, con lo cual el agua sale a través del filtro completamente purificada.

Las características que permiten determinar si el agua ha sido correctamente filtrada incluyen:

  1. El agua sale cristalina, es decir, sin ningún tipo de color que evidencie la presencia de contaminación.
  2. El pH del agua potable debe oscilar entre valores normales (6,5 a 8,5)
  3. No debe contener metales tales como plomo, arsénico o cadmio (altamente tóxicos)
  4. No debe contener microorganismos

in an experiment 3.5g of element A reacted with 4.0g of element G to form a compound Calculate the empirical formula for this co
kolezko [41]

Additional information

Relative atomic mass(Ar) : A=7, G=16

The empirical formula : A₂G

<h3>Further explanation</h3>

Given

3.5g of element A

4.0g of element G

Required

the empirical formula for this compound

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.

The empirical formula also shows the simplest mole ratio of the constituent elements of the compound

mol of element A :

\tt mol=\dfrac{mass}{Ar}\\\\mol=\dfrac{3.5}{7}=0.5

mol of element G :

\tt mol=\dfrac{4}{16}=0.25

mol ratio A : G = 0.5 : 0.25 = 2 : 1
