Imagine the made up elements A,B,C, and D form the ions A3+, B3+, C3+,  and D3+. The following reactions show the interactions that do or don't occur.  A3++B=> B3+ + A A3+ + C => no reaction  B3+ + D=> B + D3 B3+ + C=> no reaction.  Order the species from easier to harder to reduce

In the following oxidation-reduction chemical reaction which chemical species is getting reduced? Hint: Oxygen oxidation number is -2 in Cr207 (ag)and -1 in H2O2(aq) and 0 in O2(g). Hydrogen oxidation number is +1. 2- %3D O2(3) Cr3+ (aq) H2O2(aq) + Cr2O,2 ag)

Calculate AG° for the reaction 3NO,(g) + H,O(I) --> 2HNO,(l) + NO(g). AG{(kJ/mol) H;O(1) HNO3(1) NO(g) NO2(g) -237.2 -79.9 86.7 51.8 Answer to the nearest 0.1 kj/mol Answer:

1.) For the following reaction [Cd(H₂O),]+2(aq) + Br a.) If AgNO3(aq) is added what direction would the reaction (aq) → [Cd(H₂O),Br]*(aq) + H₂O() shift to and why? Note that: Ag (aq) + Br (aq) → AgBr(s)
