Answer:

Wind energy

Explanation:

An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.

Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.

Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.

This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.

What does the chemical formula of a molecule determine?
blsea [12.9K]
Since table salt is an ionic compound, the formula implies that numbers of Na+<span> ions, and Cl</span>-<span> ions are the same in the solid. The subscript numbers in an empirical formula should have no common divisor. A </span>structural<span> formula reflects the bonding of atoms in a molecule or ion.
