First we need to deterine the extinction coefficient for the system at 710 and 740 nm. At the highest [HCl] the solution is essentially all [CoCl4]-2, the [Co(H2O)6]+2 can ignored. What is the extenction coefficient for 740 nm?

Which form of relativism states that people rely on their own standards of right and wrong when making a decision?

In a heat engine of 1000 j of heat enters the system and the piston does 500 j of work what is the final internal energy of the system if the inital energy was 2000 j we have to do all of these down here 1)write the equation 2)list out your know variables 3)plug the numbers into the equations 4)solve 5)write your solution statemtn that includes inital energuy and final energuy added

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
