Determine which of the following reactions are oxidation-reduction reactions and which are not. what type of reaction do you have if it is not an oxidation-reduction reaction? show half-reactions for the redox reaction. show all oxidation numbers for the redox reactions. for all non-redox reactions, give correct ionic equations.
A.) 3Zn(s)+2CoCl3(aq)-->3ZnCl2(aq)+2Co(s)
B.)ICl(s)+H2O(l)--> HCl(aq)=HIO(aq)
C.) 2HCl(aq)+HNO3(aq)--> Cl2(g)+NOCl(g)+2H2O(l)
D.) Fe2O3(s)+3CO(g)--> 2Fe(s)+3CO2(g)
What mass of sucrose should be combined with 467 g of water to make a solution with an osmotic pressure of 8.30 atm at 300 K? (Assume the density of the solution to be equal to the density of the solvent.)
