Question 1 (1 point) Redox reactions stand for oxidation/reduction reactions. True or false: an oxidation reaction is always paired with a reduction reaction. Question 1 options: True False Question 2 (2 points) A species that is oxidized has lost electrons. This means the oxidation number of this species has: Question 2 options: Increased Decreased Stayed the same Question 3 (2 points) Which of the following is the balanced half -reaction for the oxidation of Cu to Cu+2? Question 3 options:...

Again consider the following unbalanced oxidation - reduction reaction: Ba(OH)2(aq) + H2O2(aq) + CIO2(aq) + Ba(CIO2)2(s) + O2(g) Balance this reaction for basic conditions. Once both half reactions are ready to add to give the overall balanced reaction, the number of electrons lost ( = the number of electrons gained) is O 2 O 3 O 1 O none of these
Show how using half-reactions may be used to balance (relatively) complex oxidation/reduction reactions such as the following reaction in basic solution: Let's try this problem together - feel free to answer the first couple of questions (oxidation states) and then the next person can take over.....by the end we can solve it all together. What is the oxidation state of sulfur (S) in SO32-? What is the oxidation state of sulfur in SO42-? Write the appropriate half-reaction in a basic...
any oxidation-reduction reactions can be balanced by i spection. Try to balance the following reactions by inspection In each reaction, identify the substance reduced and the sub stance oxidized. a. Al(s) + HCl(aq)→AICI3(aq) 12(g) b. CH4(g) + S(s) → CS2(l) + H2S(g) c. C3H8(g) + O2(g) → CO2(g) + H2O(1) d. Cu(s) + Ag+(aq) → Ag(s) + Cu2+ (aq)
Chemical equations of reduction–oxidation (redox) reactions can be quite nontrivial to balance. To do so, you begin with balancing the number of electrons some particles lose in oxidation and other particles gain in reduction. Consider a reaction between potassium permanganateKMnO4 andhydrochloricacidHCl(aq), which can be used in a lab to produce chlorine gas Cl2. In this reaction, a MnO− 4 ion is reduced to a Mn2+ ion by getting electrons from Cl− and losing its oxygen atoms to bind with H+...
