Hello!
The greatest negative impact of a new hydroelectric dam is the changes in the surrounding landscape.
Hydroelectric dams are among the cleanest energy sources, they don't generate waste, pollutants or atmospheric emissions. The negative impact is given by the landscape transformation needed to take advantage of the natural conditions of the dam. They stand out wherever they are, so it is important to consider the aesthetic aspect when building a dam.
Have a nice day!
Answer:
The answer to your question is letter c. Ca(NO₃)₂
Explanation:
Data
Ca(NO₃)₂ = 3.4 moles
Li₃PO₄ = 2.4 moles
Reaction
3 Ca(NO₃)₂ + 2 Li₃PO₄ ⇒ 6 LiNO₃ + Ca₃(PO₄)₂
Process
Calculate the proportion theoretical and experimental of reactants and compare these proportions.
Theoretical proportion
Ca(NO₃)₂ / Li₃PO₄ = = 1.5
Experimental proportion
Ca(NO₃)₂ / Li₃PO₄ =
As the experimental proportion is lower than the theoretical proportion we conclude that the amount of Li₃PO₄ increased in the experiment so the limiting reactant is Ca(NO₃)₂.
Answer:
A red giant is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K or lower.
