An unknown solution of triiodide registers an absorbance of 0.782 at 362 nm. a series of triiodide solutions of known concentration were analyzed at this wavelength and a standard curve was created. the equation of the best fit line from the standard curve was determined to be a = (3.2 x 10^-1 m^-1)c, where a= absorbance and c is the concentration of the solution. the constant value in this equation is the value of el. what is the concentration of the triiodide in the unknown solution?

Does the number of ions in solution increase, decrease, or remain constant? it continuously decreases. it continuously increases. it decreases at first, then increases. it increases at first, then decreases.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
