Please help!
Ligand X forms a complex with both cobalt and copper, cach of which has a maximum absorbance at 510 nm and 645 nm, respectively. A 0.217 g sample containing cobalt and copper was dissolved and diluted to a volume of 100.0 mL. A solution containing ligand X was added to a 50.0 mL aliquot of the sample solution and diluted to a final volume of 100.0 mL. The measured absorbance of the unknown solution was 0.493 at 510...

me know what to do
1 - One engineer is studying a specific mathematical modeling for one of his projects and came up with the following system of differential equations: But the system above does not produce an oscillatory behavior as he expected. (a) Solve the system (1) to make sure the engineer did not make any mistake. (b) After realizing the system did...
