What would be the optimum wavelength for generating a Beer’s law calibration curve for crystal violet and measuring absorbance versus time for the reaction of CV+ with OH- ? Explain your answer. Recall that absorbance measurements are most accurate and sensitive in the range 0.2–1.0.

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

explanation:

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
