Fill in the following blanks. As the dye concentration increases, the absorbance of the light [linearly increases, linearly decreases, exponentially increases or exponentially decreases]. The dye concentration units are [molar (M), millimolar (mM) or grams per liter (g/L)] . Although most people wrongly conclude that absorbance has units nm, in fact, absorbance is unitless. This is because it results from a ratio of light through a colored sample relative to light intensity through a clear (blank) sample. The units for the slope of the graph would be [mM, 1/mM or nm] . Hint: the slope is the change in y values divided by the change in x values. The units for the y-intercept of the graph would be [nm, nM or unitless] . The value for the slope of the line that describes the absorbance data is [6.4597 or 0.0008] The value for the y-intercept of the line that describes the absorbance data is [6.4597 or 0.0008] .
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
