A solution with a pH of 6.52 has a hydronium ion concentration of 3.02x10-7 mol/L and a hydroxide ion concentration of 3.31x10-8 mol/L.
The hydronium ion concentration of a solution can be calculated from pH by using 
. For a pH of 6.52, hydronium ion concentration is 3.02x10-7 mol/L.
The concentration of hydroxide ions can be determined by identifying the value of pOH. The sum of pOH and pH is equal to 14, which is based on the negative logarithm of the ion-product constant of water. At a pH of 6.52, pOH is equal to 7.48.
The relationship between pOH and hydroxide ion concentration is the same as the relationship between pH and hydronium ion concentration. With this, the hydroxide ion concentration at pOH of 7.48 is 
or 3.31x10-8 mol/L.

Answer:
During oxidation of organic compounds by molecular oxygen to produce carbon dioxide and water electrons will move from carbon to oxygen due to which energy will release.
Explanation:
Electrons move towards atoms which have higher affinity for them (like oxygen atoms) from atoms which have lower affinity like carbon atoms therefore the oxidation of organic compounds by molecular oxygen to produce CO2 and water release free energy since during oxidation of organic compounds by molecular oxygen to produce carbon dioxide and water electrons will move from carbon to oxygen due to which energy will release.
The answer is True. Transportation is used by cars, airplanes, trains, and many other things.
