It depends on the habitat if it was a habitat by a lake or creek it would affect the inhabitant's access to water.
Answer:
Explanation:
pressure of dry nitrogen gas at 20° = Partial pressure of nitrogen and partial pressure of water at that temperature .
The pressure of dry nitrogen gas= total pressure - vapour pressure of water at 20°C
= 200 k Pa - 2.34 k Pa
= 197.66 kPa.
Answer:
11
Explanation:
Moles of KOH =
Volume of water = 10 liters
Concentration of KOH is given by
is strong base so we have the following relation
So, pH of the solution is 11
