Gasses contain highly energetic particles which tend to spread out to fill the room/ container they are in. Often when a smell rises, there is a high concentration of gas molecules in the rising smell. Here diffusion occurs where the molecules spread out randomly moving from an area of high concentration of gas molecules to areas of low gas molecules.
<h2>Hello!</h2>
A sustainable practice is B. Setting usage limits on a resource
<h2>Why? </h2>
Sustainable practices are those that aim to reach an equilibrium between the use of natural resources for human development, and the preservation of the environment for future generations.
Setting usage limits on a resource is a sustainable practice because it allows for taking advantage of the resource, while providing constraints to its use, forcing the industry to be creative and develop alternative methods that take better advantage of that resource, or that use different resources (e.g. limiting fossil fuel emissions, forcing the industry to find alternative ways to generate power like solar energy).
Have a nice day!
Answer:
electron gain
Explanation:
e- is for electron gain while
e+ is for electron loss
In SiCl₄, the silicon-chlorine single bonds are polar.
Silicon is enveloped with four chlorine atoms. Chlorine is more electronegative in comparison to silicon. As chlorine exhibits more electronegativity, it fascinates bonding electrons towards it. Therefore, the direction of the polarity arrows should point away from the central silicon atom.
