Given:
25.0mL NaOHRequired:
molarity of NaOH
Solution:
M1V1 = M2V2
(25.0mL) M1 = (0.132 M HCl)( 17.4 mL)
M1 = 0.092 M NaOH
V1 = 0.5 liters
Explanation :
The amplitude, wavelength and time period of three waves are given.
We know that energy of a wave is given by :
It is clear that energy of a wave is inversely proportional to the wavelength i.e
So, the wave having less wavelength will have the greatest energy.
Also, we know that energy of a wave is directly proportional to the square of amplitude i.e.
So, again the wave having maximum amplitude will have maximum energy.
Hence, the correct option is (C) i.e. "amplitude = 14 cm; wavelength = 7 cm; period = 12 seconds".
The equation for the energy of a wave is given by the equation of E = A^2 where E is the energy of the wave and A is the amplitude. The higher the amplitude, the greater the energy of the wave is and vice versa. An amplitude of 14cm has the greatest energy of the wave followed by 12cm and then 7cm.
Answer:
False is your answer
The statement is false. The <ul> element is for unordered lists, while the <dl> elements along with <dt> and <dd> are used for description lists in HTML.
The statement that the grouping element, <ul>, contains the definition associated with a term from a description list is false. In HTML, the <ul> element is used to create an unordered list, typically represented by bullet points. The definitions associated with terms in a description or definition list are contained within a <dl> element. Within this <dl> element, each term is denoted by a <dt> (description term) element, and the corresponding definition is provided within a <dd> (description details) element. It's important to use these specific elements to ensure proper semantics and accessibility on the web.

a. ethanol.
b. gasoline.
c. opiates.
Answer:
Alcohol contains A. ethanol.
Explanation:
Alcohol beverages are drinks that contain more than a minimal amount of ethyl alcohol or ethanol. Ethanol is a chemical compound, considered the main type of alcohol. It is produced by grain fermentation and used as a solvent, as an additive to gasoline and as the intoxicating ingredient of beer, wine, distilled spirits and other beverages.
Energy emitted from stars is the result of fusion.
Fusion is a process where two or more atoms combined together to form a new molecule.
As in the question it is stated that Luminosity is the amount of energy emitted by a star each second is true, because of the fusion of hydrogen atoms to helium atom and high amount of energy is released in the form of light. And Stars radiate light over a broad range of frequencies in the electromagnetic spectrum, from the low energy radio waves to high energy gamma rays.
Hence, due to fusion energy is emitted from stars in the luminous.

Answer: industrial smog.
Explanation:
The industrial smog typically exists in the urban industrial areas where the large scale burning of the fossil fuels may lead to generation of huge amount of smoke and sulfur dioxide gas liberated into the atmosphere. These gaseous products gets mixed with the droplets of fog already present in the atmosphere. This lead to the formation of industrial smog. The industrial smog forms a thick blanket of smog or haze nearly close to the ground.
Sulfur dioxide is a primary component of industrial smog and photochemical smog, but it does not directly influence thermal inversion. It is released into the atmosphere predominantly from burning fossil fuels.
Sulfur dioxide is a significant component in the creation of both industrial smog and photochemical smog, two serious urban air pollutants. During industrial activities, fossil fuels such as coal and oil that contain sulfur are burned, releasing sulfur dioxide into the atmosphere. This gas then reacts with water vapor and other compounds to form industrial smog. In the case of photochemical smog, when sulfur dioxide interacts with sunlight, volatile organic compounds, and nitrogen oxides, it contributes to the formation of this harmful type of smog. However, sulfur dioxide does not directly relate to the occurrence of thermal inversion, a weather-related phenomenon that can trap smog and other pollutants close to the ground.
