A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent. In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant. 2. In a redox reaction, the reducing agent is oxidized and it gains electrons. In a redox reaction, the oxidizing agent is reduced and it gains electrons. 3. Bending stress is also known as flexural stress. The test used in observing the mechanical strength of chocolate is the three-point bend test. 4. The flexural strength of materials may be expressed in Pascals. Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.
