Question

12 g of magnesium ribbon was heated in the crucible at the end of the reaction 20 g of magnesium oxide have been produced what mass of oxygen had reacted with magnesium

Answer 1

Answer:

The quantitative stoichiometric relationships governing mass and amount will be studied using the combustion reaction of magnesium metal. Magnesium is reacted with oxygen from the air in a crucible, and the masses before and after the oxidation are measured.
