Algunas acciones viables para utilizar los recursos ambientales de forma racional y con el objetivo de reducir la contaminación son:
- Reducir, reciclar y reutilizar los residuos generados en el hogar.
- Reducir el uso de vehículos de combustión interna.
- No quemes basura al aire libre
- No utilices aerosoles ni frigoríficos que dañen la capa de ozono.
<h3 /><h3>¿Qué importancia tiene la sostenibilidad?</h3>
Es fundamental para la preservación y mantenimiento del medio ambiente y la calidad de vida de las generaciones actuales y futuras. El desarrollo de acciones sostenibles promueve la protección del medio ambiente, los ecosistemas y los recursos naturales.
Por lo tanto, todas las personas e instituciones económicas pueden promover la sostenibilidad a través de prácticas fáciles de ejecutar que ayuden a preservar y proteger el medio ambiente.

what are the statements that you are able to choose from or do you just have to know?
Answer:
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
Explanation:
It is recommended only for the second type of candy to be taken off the market.
Based on the background information, if a candy shows a 0,62 Rf value in the chromatography it is considered potentially dangerous, and therefore it should be taken off the market.
The Rf value is calculated using the following formula:
- Rf = Total distance traveled by a component/ Total distance from the pencil line to the solvent front
Now, let's find out if any of the components has an Rf equal to 0,62.
Note: To determine the distances I measured the image using a ruler and you can do the same, this will not alter the results.
- Sample 1
- Total distance traveled by the component: 6cm
- Total distance: 7 cm
- Rf : 6 cm/ 7 cm = 0.85
2. Sample 2
- Total distance traveled by the component: 4.34cm
- Total distance: 7 cm
- Rf : 4.34 cm/ 7 cm = 0.62
This means sample 2 has the 0.62 Rf value and therefore it needs to be taken off the market.
