In the Fender's blue simulation you explored in Exercise 2 of this lab (Hot and Bothered), with periodic fires turned ON, which patch configuration is likely to be better for Fender's blue butterfly persistence, and why?
The Small Near configuration, because butterflies can more easily recolonize patches that burned The Small Near configuration, because detrimental edge effects are more pronounced with smaller patchesThe Large Far configuration, because detrimental edge effects are less pronounced with larger patchesThe Large Far configuration, because butterflies in large patches are less likely to perish in fires.
Problem- The decomposition of NH2OH shows a k value of 0.237x10^-4 L/mol.s at 0C and 2.64x10^-4 L/mol.s at 25C. The activation energy is 65.2 kJ/mol. Calculate A (pre exponential factor).
The reaction is first order and has a rate constant of 6.2 ? 10-5 /s at 35?C when the H+ concentration is 0.10 M. Suppose that the initial concentration of sucrose in the solution is 0.40 M. How many minutes will it take for the sucrose concentrat..
