Answer:
The molarity of sodium chloride in sea water is 0.479 M
Explanation:
Step 1: Data given
Mass of NaCl = 28.0 grams
Molar mass NaCl = 58.44 g/mol
Step 2: Calculate moles
Moles NaCl = mass NaCl / molar mass NaCl
Moles NaCl = 28.0 grams / 58.44 g/mol
Moles NaCl = 0.479 moles
Step 3: Calculate molarity NaCl in sea water
Molarity = moles / volume
Molarity NaCl = 0.479 moles / 1L
Molarity of NaCl in sea water = 0.479 mol/L = 0.479 M
The molarity of sodium chloride in sea water is 0.479 M

Explanation:
Renewable energy sources refers to those energy sources that can never be depleted. This means that they can be used severally without getting exhausted. Solar, biomass, wind and hydroelectric power are all renewable energy sources.
Hence, from the perspective described above, we can say that wind is a form of solar energy because wind is formed when the air is heated by the sun.
Hydroelectric power is driven by the water cycle. This water cycle somehow depends on the sun to run efficiently. So, hydroelectric power can also be considered to be a form of solar energy.
This is coordinate (dative) bonding where the nitrogen atom donates 2 electrons to the oxygen but is still chemically bonded.
The electons are in the atmosphere
