Answer: Groundwater and surface water are connected. When groundwater is overused, the lakes, streams, and rivers connected to groundwater can also have their supply diminished. Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

Answer: Transpiration is a process process in which plants absorb the water through their roots and then release it in the form of water vapour through small pores located in the leaves of the plants.
Explanation:
Transpiration is very important for the life in our planet.
Transpiration is define as a process in which plants absorb the water through their roots and then release it in the form of water vapour.
The process of transpiration occurs through small pores which are located in the leaves of the plants.
Therefore, this process is essential to cool plants and it helps them to mantain their temperature.
The rate of transpiration depends on the following factors:
1. The humidity.
2. The light.
3. The temperature.
4. Water in the soil.
5. Wind.
6. Soil water.
Answer:
Ba(OH)2 + 2 HCl → BaCl2 + 2 H2O
The reactants are present in equimolar amounts, so there is no excess or limiting reactants.
(0.0500 L) x (0.600 mol/L HCl) x (2 mol H2O / 2 mol HCl) = 0.0300 mol H2O
(4.184 J/g·°C) x (50.0 g + 50.0 g) x (25.82 - 21.73)°C = 1711.256 J
(1711.256 J) / (0.0300 mol H2O) = 57042 J/mol = 57.0 kJ/mol H2O
Explanation:
The chemical reaction is given as:
<span>C8H10+3O2 = C8H6O4+2H2O
We are given the initial amount of para-xylene for the reaction. We use this amount and the relation of substances from the reaction to obtain the amount of the acid produced.
204 g ( 1 mol / 106.18 g ) ( 1 mol C8H6O4 / 1 mol C8H10 ) ( 166.14 g / mol ) = 319.20 g terephthalic acid</span>
