consider the following substance:\n\nmn₂o₇\nin the boxes that follow type in the appropriate oxidation number. remember to indicate whether they are positive or negative:\n1. manganese\n2. oxygen\n\n1.\n\n2.

Answer

Explanation:

Step1: Determine the oxidation number of oxygen

In most compounds, oxygen has an oxidation number of (- 2).

Step2: Calculate the oxidation number of manganese

Let the oxidation number of manganese be (x). For the compound (Mn_2O_7), using the rule that the sum of oxidation numbers in a neutral compound is (0). We have (2x+7\times(-2) = 0). Simplify the equation: (2x-14 = 0). Add (14) to both sides: (2x=14). Divide both sides by (2): (x = + 7).

Answer:

  1. (+7)
  2. (-2)
