Compare the costs of using renewable resources to the costs of using nonrenewable resources.
Vitek1552 [10]

Answer:

Sample response:

The costs of using both renewable and nonrenewable resources depend on the extent of the use. If renewable resources are managed wisely, the use of the resource will not exceed the rate at which it is replenished. In this instance the cost of using renewable resources can be minimized, if not entirely eliminated. The cost of using nonrenewable resources is harder to minimize because nonrenewable resources cannot be replenished at the rate at which they are used. The environmental impact of using nonrenewable resources such as fossil fuels is greater than just the loss of the resource itself. Other impacts such as acid rain, global warming, and atmospheric pollution can result from the use of nonrenewable resources.

Aliun [14]
<h2>Hydrogen Bonding</h2>

Explanation:

  • Hydrogen bonding is a type of weak bond.
  • Hydrogen Bonding occurs when the hydrogen atom of one molecule is bonded with a molecule of high electronegativity element like nitrogen of another molecule.
  • It is a type of dipole-dipole interations.
  • The nitrogen is a highly electronegative element that forms a weak bond with the hydrogen atom of another molecule with dipole-dipole interaction.
  • Hydrogen bonds are weaker than covalent and ionic bonds.
  • Therefore the type of bond is Hydrogen bond.
