A 2 gram Magnesium (Mg) ribbon is burnt in air . The burnt ribbon is collected and weighed. Would it be greater than 2 grams or lesser?

more than two grams because the magnesium bonds with oxygen when energy is added and forms MgO

The products would be equal to the mass of the reactants as it states in the law of conservation of mass.

2Mg + O₂ → 2MgO

The 2 gram ribbon plus the weight of the oxygen required produces 2 grams plus the weight of the oxygen used.
