Here are the solutions to the questions: 5. The systematic name of the compound SO_3 is determined by the elements present and their oxidation states. Sulphur (S) and three oxygen (O) atoms. Oxygen typically has an oxidation state of -2. For SO_3 to be neutral, the sulphur must have an oxidation state of +6 (x + 3(-2) = 0 x = +6). The prefix "tri-" indicates three oxygen atoms. Therefore, the systematic name is Sulphur(VI) trioxide. The correct option is D. 6. Let's evaluate each statement: I. Pests are always found in crops and animals. Pests are organisms that cause damage to crops, livestock, or
