The formula for pH given the pKa and the concentrations
are:
pH = pKa + log [a–]/[ha]
<span>
Therefore calculating:</span>
3.75 = 3.75 + log [a–]/[ha]
log [a–]/[ha] = 0
[a–]/[ha] = 10^0
<span>[a–]/[ha] = 1</span>
Answer:
urban heat island
Explanation:
occurs when a city experiences much warmer temperatures than nearby rural areas.

VSEPR theory (known as Valence Shell Electron Pair Repulsion ) endeavors to explain/predict the shape and geometry of molecules. The theory postulates that atoms in a molecule take a position in space (within the molecule) that reduces the repulsion of the individual atom’s electron clouds so the molecule can achieve the most stable state.
Answer:
An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. It has multiple applications in research and engineering, with common usage in hydroponics, aquaculture, aquaponics, and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.
