Question
Consider this reaction: Write the net ionic equation for the reaction. Which reactant is Assume the reaction goes to completion. Which has the greater activity Cl_2 or Br_2? The formation reaction for Fe_2O_3 is: How many grams of oxygen will react when 250.0 g of iron react? How many moles of iron are required to produce 7.75 moles of iron (III) oxide? If 603.5 kJ of heat were released by the reaction, how many moles of O_2 must have reacted? Consider the reaction: Calculate the molar mass for hydrochloric acid. If 3.183 moles of KMnO_4 and 800.0 g of HC1 are allowed to react, which is the limiting How many moles of CI_2 will be produced?Explanation / Answer
6)
Cl2 + 2NaBr --> 2NaCl + Br2
a) net ionic
Cl2 + 2Na+(aq) + Br-(aq) --> 2Na+(aq) + 2Cl-(aq) + Br2(l)
Cancel spectator ions
Cl2 + Br-(aq) --> 2Cl-(aq) + Br2(l)
b)
oxidizing agent is the one that contains the reduced element... that is Chlorine (Cl 0 --> Cl-) then Cl2 is the oxidizing ageng
reducing agnet is the one with oxidized element... Br-1 --> Br0 then the NaBr(aq) is the reducing agent
c)
The higher activity is the one with higher charge and electronegativity. in this case it will be Cl2
