Answer:
there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region.
4.2 × 10²² atoms Al × (1 mol Al / 6.022 × 10²³) = moles Al
Last one: fraction 1 mole Al over 6.022 × 10²³ atoms Al
The answer is B, the electrolysis of water. One cannot be the answer since the condensation of steam requires a loss of heat, an exothermic reaction. Numbers 2 and 3 cannot be correct either as they do not indicate energy in the chemical equation, and so it must be balanced throughout. Meaning that the only possible answer is B.
<span>Water is known to be the
universal solvent because it can mostly dissolve most of the substances. The
reason behind its solvability is the bonding of intermolecular forces of attraction.
The answer is letter B. Out of the many bondings between molecules, the bond
that governs water is H bonding or hydrogen bonding. Water is composed mostly
of two atoms of hydrogen one atom of oxygen. Both the hydrogen and oxygen are
polar elements and hydrogen is bounded with a high electronegativity oxygen atom.</span>
