Why should a graph of absorbance versus concentration go through the origin?
A graph of absorbance versus concentration should pass through the origin because, according to Beer-Lambert Law, absorbance is directly proportional to concentration. When the concentration of a solution is zero, there are no absorbing species present, resulting in zero absorbance. This linear relationship indicates that as concentration increases, absorbance increases proportionally, reinforcing that the graph should start at the origin (0,0). Any deviation from this could indicate issues such as instrument calibration errors or scattering effects.
What would be a better graph to use instead of a tally graph?
a pictograph
How would you tell what type of graph you use?
You usually want to use a bar graph. If you have a year of data you probably want to use a line graph.
Which type of graph would you use to show the number of pages in each book on the shelf and what graph?
bar graph
What graph use vertical and horizontal bars to make comparison?
That would be a bar graph.
Can you explain the relationship between absorbance and wavelength in a graph?
In a graph, absorbance is typically shown on the y-axis and wavelength on the x-axis. The relationship between absorbance and wavelength is that as the wavelength of light increases, the absorbance generally decreases. This is because different substances absorb light at specific wavelengths, so the absorbance of a substance can vary depending on the wavelength of light being used.
What does Wavelenght vs absorbance graph depicts in u-v spectroscopy?
A wavelength vs absorbance graph depicts in uv spectroscopy shows the different colored wavelenths of UV light and how they are absorbed and percieved, and which ones are visible and which ones are not.
What type of graph would you use to display the ages of students in your classroom?
The type of graph you would use would be a PICTURE GRAPH or a TALLY CHART
What would a scientist use a graph for?
A scientist would not use a graph to explain the methodology.
What would a scientist not use a graph for?
A scientist would not use a graph to explain the methodology.
What is the specific absorbance of aspirin?
If you have a spectrofotometer ( the thing to mesure the absorbance) then play with the setting and use a maximum. this will lay close to your specific absorbance or take the pharmacopea or a MERCK index
What graph would you use to show monthly temperature for the year?
You can use a bar graph or a line graph.
What type of graph do you use when you are comparing things that is not a double bar graph?
you would use a line graph
What graph would you use to graph mph and miles of a trip?
line graph
Why you use semi-log graph over normal graph?
why would you use a semi-logarithmic graph instead of a linear one?what would the curve of the graph actually show?
Why do chemists prefer to read the absorbance rather than the percent transmittance of lght when analyzing a sample having a visible color?
Chemists prefer to read the absorbance rather than the percent transmittance of light when analyzing a sample with a visible color because absorbance is directly proportional to concentration according to the Beer-Lambert Law. This allows for more accurate quantification of the sample's components. In contrast, percent transmittance may not provide a linear response and can be influenced by factors beyond just concentration, such as the color of the sample itself.
What would be the best graph or chart to use to compare and contrast information?
A bar graph would be the best graph or chart to use to compare and contrast information.
