The Hoover Dam in Nevada, supplied by Lake Mead, generates hydroelectric power for several western states, including the numerou

s lights in Las Vegas. What statement accurately explains the potential energy that Hoover Dam uses to generate this power?
A) The large number of generators and height of the dam account for the potential energy.
B) The depth of Lake Mead and the large number of generators account for the potential energy.
C) The amount of water released through the dam and the dam's height account for the potential energy.
D) The quantity of water flowing into Lake Mead from the Colorado River accounts for the potential energy.

Answer: 
C).The amount of water released through the dam and the dam's height account for the potential energy.  
because energy is directly proportional to the amount of water released. according to the height of the dam ,the speed of the water will increase.

Potential energy = mgh

where

m = mass

g = acceleration due to gravity

h = height

So more the height higher the potential energy

also

more the mass (amount) of water higher the potential energy

acceleration due to gravity is a constant for earth.

hence we can say that

The amount of water released through the dam and the dam's height account for the potential energy.

Which term is used to describe the reactant that is used up completely and controls the amount of product that can be produced d
givi [52]

Answer: Option (c) is the correct answer.

Explanation:

A limiting reagent is defined as a reagent that completely gets consumed in a chemical reaction. A limiting reagent limits the formation of products.

For example, we have given 5 mol of A and the reaction is 2A + 4B \rightarrow 2AB

Whereas when 4 mol B will react with 2 mol of A. Hence, 8 mol of B will react with 4 mol A as follows.

                        \frac{2}{4} \times 8 = 4 mol

As, the given moles of A is more than the required moles. Thus, it is considered as an excess reagent.

Hence, B is a limiting reagent because it limits the formation of products.

Thus, we can conclude that limiting reactant is the term used to describe the reactant that is used up completely and controls the amount of product that can be produced during a chemical reaction.

What are the uses of solution?<br>​
Ilia_Sergeevich [38]

Answer:

The majority of chemical processes are reactions that occur in solution. Important industrial processes often utilize solution chemistry. "Life" is the sum of a series of complex processes occurring in solution. Air, tap water, tincture of iodine, beverages, and household ammonia are common examples of solutions.

four types of solution:

Turpentine as a solvent are used in the production of paints, inks and dyes. ↔Water as a solvent is used in the making of food, textiles, soaps and detergents. ↔Alloys are solid solutions that are used in the manufacture of cars, aerospace and other vehicles.

Why are fluorine (F), chlorine (Cl), and iodine (I) in the same group of the periodic table?
Verdich [7]

Fluorine (F), Chlorine (Cl) and Iodine (I) are all found in the same group on the Periodic Table because they have similar physical properties. Since they are all Halogens, they have 7 valence electrons in their outer shell. In order to get a total of 8, they naturally combine with elements of the same isotope (itself), so D comes close to being correct, but it's not the best answer choice.
