The heat island effect or the the urban heat island effect, is where the temperature of an area is higher than close rural areas. This is because materials suh and concrete and asphalt absorb the sunlight and store it, causing extreme weather.
Answer:
[H₃O⁺] = 7.08×10⁻⁹ M
Explanation:
pH = - log [H₃O⁺]
[H₃O⁺] = 10^⁻pH
Therefore, [H₃O⁺] = 10⁻⁸¨¹⁵
[H₃O⁺] = 7.08×10⁻⁹ M
