The wavelength of maximum absorbence relates to the color, because the only color that is not absorbed will be the color of the item. For example, plants are green because they absorb red and blue light, and reflect green light.
The absorbance of a substance is directly proportional to its concentration. This means that as the concentration of a substance increases, its absorbance also increases. This relationship is described by the Beer-Lambert Law, which states that absorbance is equal to the product of the substance's concentration, the path length of the light through the substance, and the molar absorptivity of the substance.
The Beer-Lambert law Absorbance = (extinction coefficent)(pathlength of light)(concentration) allows you to measure the absorbance of sample in a UV spec, and change the rate from absorbance units / time to change in concentration / time. the pathlength of light being the width of the cuvette and the extinctin coefficent being specific to the product molecule.
When a substance has a low pH, it means that it is acidic. pH is a measure of how acidic or basic a substance is on a scale of 0 to 14, with lower numbers indicating higher acidity. So, a substance with a low pH has a high acidity level.
To use stoichiometry to determine the concentration of a substance, you need to first balance the chemical equation for the reaction involving the substance. Next, determine the moles of the known substance and use the balanced equation to relate it to the moles of the unknown substance. Finally, calculate the concentration of the unknown substance in terms of moles per liter based on the volume of the solution.
Yes, stoichiometry is commonly used to relate the number of moles of one substance in a chemical reaction to the number of moles of another substance involved in the same reaction. This helps in determining the ideal ratio of reactants and products in the reaction based on the balanced chemical equation.
The absorbance of a substance is directly proportional to its concentration. This means that as the concentration of a substance increases, its absorbance also increases. This relationship is described by the Beer-Lambert Law, which states that absorbance is equal to the product of the substance's concentration, the path length of the light through the substance, and the molar absorptivity of the substance.
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
Inversely frequency = speed of light / wavelength
fgyg
The product of (wavelength) times (frequency) is the speed.
The product of (wavelength x frequency) is the wave's speed.
The speed of any wave is the product of (wavelength) x (frequency) .
The Beer-Lambert law Absorbance = (extinction coefficent)(pathlength of light)(concentration) allows you to measure the absorbance of sample in a UV spec, and change the rate from absorbance units / time to change in concentration / time. the pathlength of light being the width of the cuvette and the extinctin coefficent being specific to the product molecule.
Energy is inversely proportional to wavelength: the shorter the wavelength (X-rays, gamma rays) the greater the energy.
The wavelength of an electromagnetic wave is inversely proportional to its frequency. This means that as the frequency of the wave increases, its wavelength decreases, and vice versa.
Frequency and wavelength are inversely related. This means that as the frequency of a wave increases, its wavelength decreases, and vice versa. This relationship is described by the formula: speed = frequency x wavelength.
Wave speed is dependent on both wavelength and period. The relationship is described by the formula: wave speed = wavelength / period. As wavelength increases, wave speed also increases. Conversely, as period increases, wave speed decreases.
