Which of the following is true about oxidation reactions?
A. Oxidation reactions are the principal source of energy on Earth.
B. All oxidation reactions are accompanied by reduction reactions.
C. The burning of wood in a fireplace and the metabolization of food by your body are oxidation reactions.
D. all of the above
Well, B and C are correct. Now on A, it seems to me that the Sun is the principal source of Energy on Earth, however, I am not certain what the answer writer had in mind when she wrote "on Earth". If she meant energy produced on Earth, then that will not include the Sunlight....in that case, answer d. So I dunno.
The phenomenon of coupling always involves ? oxidation and reduction reactions decarboxylation reactions reactions that produce energy and related reactions that require energy esterification and oxidation reactions None of the
What makes this an oxidation-reaction? 3Ag2S+2Al(s) -> Al2S3+6 Ag(s)? Write the half-reactions showing the oxidation and reduction reactions. Identify which is the oxidation reaction and which is the reduction reason. What is
Classify the following reactions as precipitation reactions, oxidation-reduction reactions, or acid-base reactions. 1)2NaCl(aq)+K2H2Sb2O7(aq)==Na2H2SbO7(s)+2KCl(aq) 2)(CH3COO)2Cu(aq)+(NH4)2C2O4(aq)==CuC2O4(s)+2CH3COONH4(aq)
Balancing Complete Redox Reactions I need help on the half reduction part for both reduction and oxidation of Cl2(g) --> cl^1- (aq) + OCl^1- (aq). I got both of the half reactions started. Cl2 --> Cl^- (Reduction) .... Cl^1-
Use oxidation numbers to identify if this reaction is REDOX reactions. SO2(g) + H2O(l) -> H2SO3(aq) for oxidation #s I got: SO2 = -2 for the S = -2 for the o2 H20 = +1 for H2 = -2 for O --> H2SO = +1 for H2 = -2 for S = -2
The two most common oxidation states are Cr(III) and Cr(VI). Balance the following oxidation-reduction equations that involve one of these oxidation states of chromium. Assume that the reactions occur in acidic solution. A. Cr(s)
"Write equations for the half-reactions that occur at the anode and cathode for the electrolysis of the following aqueous solution: CuBr2(aq)" Possible oxidation reactions: 1. 2Br- -> Br2 + 2e- = -1.09 2. 2H2O -> O2 + 4H+ +
I'm confused with this question as I don't understand how to write the reactions. Here is the question if you could please help me with this question or just even give me an example on how to do it. I would really appreciate it.
