Answer:

pOH = 8.19

Acidic solution (pH < 7.0)

Explanation:

The pOH of the solution is defined as:

pOH = - log [OH⁻]

Since we have [OH⁻] = 6.5 x 10⁻⁹ M, we calculate the pOH as follows:

pOH = - log (6.5 x 10⁻⁹) = 8.19

To know if the solution is acidic, neutral or basic, we have to calculate the pH from the value of pOH:

pH + pOH = 14

⇒ pH = 14 - pOH = 14 - 8.19 = 5.81

The solution is acidic because pH < 7.0.

Which consequence of global warming is described as having an increase in growing season changes in migration and loss of specie
IgorLugansk [536]

Answer:

Deforestation, increase wildlife extinction, ecosystem imbalances, soil erosion, migration and loss of species.

Explanation:

Global warming is warming the earth's surface temperature, which causes the changes in our ecosystem like deforestation, soil erosion, climate changes, migration and loss of species etc.

Global warming is caused by the 'Greenhouse effect', major gases are carbon dioxide(9-26%), methane(4-9%), water vapour(36-70%) ozone(3-7%) and nitrous oxide.    

Global warming affects on the ocean include rising sea level, meiting glaciers, thermal expansion and ice sheets. It also cause the bird migration which carries high cost of predation and mortality.

Which colligative property is employed when salt is put on an icy sidewalk to melt ice?
ankoles [38]
<span>The correct answer is 'freezing point depression'. Colligative properties depend on the concentration of molecules of a solute. Examples of other colligative properties are boiling point elevation or vapour pressure lowering. The salt causes ice on the side walk to melt because it lowers the freezing point. </span>
