Polychlorinated biphenyls (PCB) are environmental and health hazard. They break down very slowly in the environment. The decomposition of PCBs can be represented by the equation:
2 C12H4Cl6 + 23 O2 + 2 H2O --> 24 CO2 + 12 HCl
a) How many moles of water are needed to react 10.0 mol PCB?
b) How many grams of HCl are produced when 15.2 mol H2O react?
c) How many moles of CO2 are produced when 76.5g HCl are produced?
d) How many grams of PCB are reacted when 100.25g CO2 are produced?
e) How many grams of HCl are produced when 2.5kg of PCB react?
What is the activation energy in kJ/mol? What is the rate constant at 100 degrees C?
Suppose that two equal volumes of 0.2 molar NaCl (aq) solutions are separated by a membrane and that the left -hand compartment of the experimental arrangement contains a polyelectrolyte molecule Na6P at a concentration of 50 g/liter
Asprin, whose structure can be found in the introduction, can be made from the reaction of a phenol and an anhydride. Give the phenol and anhydride that could be used to make aspirin?
