Answer:
Hydropower plants get their energy from falling water to generate electricity. A generator then converts the mechanical energy from the turbine into electrical energy. Hydroplants range in size from "micro-hydros" that power only a few homes to giant dams that provide electricity for millions of people. A hydroelectric dam is one of the major components of a hydroelectric facility. A dam is a large, man-made structure built to contain some body of water. In addition to construction for the purpose of producing hydroelectric power, dams are created to control river flow and regulate flooding. Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources. However, it can also cause environmental and social threats, such as damaged wildlife habitat, harmed water quality, obstructed fish migration, and diminished recreational benefits of rivers.
Explanation:
Answer:
0.053 M is the concentration of X after 196 seconds.
Explanation:
Initial concentration of the X = ![[A_o]=1.0 M](https://tex.z-dn.net/?f=%5BA_o%5D%3D1.0%20M)
Time taken by the sample, t = 196 s
Final concentration of the X after t = [A] =?
Rate constant of the reaction = k = 
Formula used :
![[A]=[A_o]\times e^{-kt}](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_o%5D%5Ctimes%20e%5E%7B-kt%7D)
where,
Now put all the given values in this formula, we get
![[A]=[1.0M]\times e^{-1.50\times 10^{-2} s^{-1}\times 196 s}](https://tex.z-dn.net/?f=%5BA%5D%3D%5B1.0M%5D%5Ctimes%20e%5E%7B-1.50%5Ctimes%2010%5E%7B-2%7D%20s%5E%7B-1%7D%5Ctimes%20196%20s%7D)
![[A]=0.053 M](https://tex.z-dn.net/?f=%5BA%5D%3D0.053%20M)
0.053 M is the concentration of X after 196 seconds.
Heat is being applied to the liquid. The right amount of heat causes the liquid to evaporate and become water vapor or steam-gas.
Answer: D. A neutron has no charge
Explanation: Neutrons are subatomic particles found inside the nucleus of an atom. This particle is neutral and has no charge at all. That is the reason why the nucleus is positively charge since only the protons exhibits a charge and the neutrons carries no charge.
