Question

Chemist preformed Reaction of solid magnesium burning and found that the mass of the magnesium oxide what is greater than the mass of the magnesium. What is the reason behind this increase in math reaction of solid magnesium burning and found that the mass of the magnesium oxide what is greater than the mass of the magnesium. What is the reason behind this increase in mass?

Answer 1

Answer:

The magnesium reacted with the oxygen in the air.

Explanation:

For argument’s sake, let’s say that the mass of magnesium oxide was 3 g and that of the oxide was 5 g.  

The reaction was

            magnesium + oxygen ⟶ magnesium oxide

Mass:           3 g                                          5 g

Mass of oxygen = 5 g – 3 g = 2 g

The 3 g of magnesium must have combined with 2 g of oxygen to form 5 g of magnesium oxide.
