the equation. a) aluminum reacts with iron (III) oxide (This is how iron is extracted from iron ore. It is heated at a high temperature with aluminum present. In the reaction, iron is separated from the iron ore producing a new aluminum compound.) 2Al + Fe. 2. O. 3. 2Fe + Al. 2. O. 3. b) sodium reacts with water (This reaction is dangerous.
Oxidation, Reduction, Agents, & Reactions. Oxidation Numbers, Application to Reactions. Elements that lie near the top of the list are referred to as active metals. Elements that lie near the bottom of the activity series are very stable and form compounds less readily.
Chem 12 Practice Worksheet - Answer Key Key page 1 Redox #1 (KEY) 1. Explain the meaning of each of the following terms: a) oxidation a half-reaction that involves the loss of electron(s) b) reduction a half-reaction that involves the gain of electron(s) c) reducing agent a species that causes another to be reduced; it itself is oxidized
Describe each reaction as spontaneous or non-spontaneous. Can you keep 1 M HCl in an iron container? If the answer is no, write a balanced equation for the reaction that would occur. Can you keep 1 M HCl in an Ag container? If the answer is no, write a balanced equation for the reaction that would occur. Can you keep 1 M HNO in an Au container?
The reaction of iron metal with oxygen to form iron (III) oxide. The complete combustion of 2,2-dimethylpropane (C4H10) in oxygen. The decomposition of hydrogen peroxide to form water and oxygen. The reaction of ammonia with sulfuric acid.
Worksheet # 4 Balancing Redox Reactions Balance each of the following half-cell reactions. (In each case assume that the reaction takes place in an ACIDIC solution.) Also, state whether the reaction is oxidation or reduction. 1. S 2 O 3 2- → SO 4 2-2. MnO 4 - → Mn2+ 3. As → AsO 4 3-4. Cr3+ → Cr 2 O 7 2-5. Pb2+ → PbO 2
