Here are the solutions to your chemistry questions: 1. An experiment magnesium ribbon was heated in air. The product formed was found to be heavier than the original ribbon. Explain the difference in observation made in a similar experiment when copper (VII) was heated in air. When magnesium ribbon is heated in air, it burns with a bright white flame and forms a white solid (magnesium oxide). When copper is heated in air, it does not burn with a flame but glows dull red and forms a black solid (copper(II) oxide). Both metals increase in mass due to the formation of their respective oxides. **2. A solution of potassium manganate (VII) was on the other hand, heated in a litre was required for complete neutralization of
