The ground water refers to water present in the under earth in the cracks or pores or similar spaces.We majorly depends upon this sources of water specially in rural area.
It helps in irrigation and also serve as drinking water supply.
The words or phrases which identify layer of ground water are:
a) water table: the uppermost water saturated layer
b) kettle lake: it is an underground lake (not ground water)
c) Saturation zone : this is the zone of water below the water table
d) undergound lake: this is kettle lake (not ground water)
e) sink hole: Not a layer of ground water
So the layers of ground water are
a) water table
b) saturation zone
Answer:
The solutions of hydrobromic acid and of chloric acid are the most electrically conductive.
Explanation:
The electrical conductivity of a solution is determined by the concentration of ions in the solution. The acids listed react with water to form ions. In the case of hydrobromic acid, for example, the reaction is as follows:
HBr + H2O >> H3O(+) + Br(-)
Hydrobromic acid and chloric acid are strong acids, meaning the reaction is considered to proceed at 100%. Acetic acid, however, is a weak acid and the reaction with water does not go to completion, so there are less ionic species in the solution of acetic acid, which makes it less electrically conductive.
The Correct choices are :
- 1. The elements have filled valence levels.
- 2. potassium (K) with a 1+ charge
