Sustainability describes the actions humans can take to try and maintain some sort of balance with the Earth Air quality, water

quality and availabilityreduced land erosion, replacing what is taken from the Earth (trees, crops, ) are just a few of the issues that sustainability deals withSelect one of the following scenarios that best describes an individual's actions that would help with sustainability.
A ) Reduced output in wind turbine blades would cut down on the carbon footprint of the factories that complete these tasks. This would help the Earth in the long run . Continually adding chemicals to sewage, after it is treated and before it is released back into the water supply, will help humans and the Earth into the foreseeable future . Adhering to scientifically backed guidelines on how to harvest and replant trees in a way that would not cause soil erosion or a loss in the biodiversity in that specific area would help the Earth in the long run D) Continued use of pesticides , herbicides , insecticides , and rodenticides will allow crops to grow and feed millions of people . The buildup of these chemicals in the environment is too small of a concern to try and change what is currently taking place

Answer:The answer is B

Explanation:

There is less water lost due to evaporation and therefore more available to plants. Mulch and minimum tillage results in twice as much available water as does deep tillage. This is an immediate benefit. We are looking for future benefits: less runoff and erosion, more soil stays in place, the soil is more fertile, and farmers use less fossil fuels.

What is the name of IBr4?<br> And is it covalent or ionic?
BlackZzzverrR [31]

Answer: The name of the IBr_4 is Iodine tetrabromide and it is a covalent compound.

Explanation:

Inter-halogen compounds are compounds which composed of two different halogen atoms. For example ;ICl_3,IF_5 etc.

The naming is done by first writing the central atom symbol's name followed by the prefix corresponding to the number of atoms of another halogen atom like: Mono for 1, di ,for 2 tri for 3, tetra for 4 , penta for 5 etc. After this name of the another halogen is written with suffix 'ide' in the end.

The name of the IBr_4 is Iodine tetra bromide.

In halogen compounds, the difference in electronegativities is not so large due to which they form covalent compounds by the means of sharing the electrons. Hence the Iodine tetrabromide  covalent compound.

Van der waals interactions result when hybrid orbitals overlap. a hydrogen atom loses an electron. molecules held by ionic bonds
vovangra [49]
<span>Van der waals interactions are the electrical interactions between two or more atoms and even molecules but the inter-molecular attractions between the molecules are not exactly strong, in fact they are the weakest. And these Van der waals interactions are happened when electrons are not symmetrical distributed in a molecule.</span>

Complete the passage about metallic bonding.
Degger [83]

In metallic bonding, valence electrons of metals move freely between neighbouring atoms. metals are ductile

because the forces that hold their atoms together are weak.

Explanation:

  • Metallic bonds are the force which holds atoms together in a metal.
  • Valence electrons present in the metals are freely moving between the other neighbouring atoms. The interaction between the positive ions which electrons leave behind and the valence electrons give the binding force which able to hold the metallic crystal together as it is.
  • In metals, the electrons are free to travel from one metal to another metal. This speciality is the reason for their electric conductivity. And this shows that the metal-metal bond is weak in metal.
