Question

In an experiment, some magnesium ribbon is weighed and its mass is recorded. It is then placed in a crucible and heated. Once hot

enough, it combines with oxygen to form magnesium oxide (Mgo). Observe the data table provided. Explain why the law of
conservation of mass appears violated.
les -
A)
The mass of the magnesium oxide was not calculated correctly.
B)
The mass of the oxygen does not equal the other two substances.
C)
The masses of the products and reactants look like they are equal.
D)
The mass of the magnesium oxide does not add up to the oxygen and
magnesium

Answer 1

i agree the answer is (D)The mass of the magnesium oxide does not add up to the oxygen and magnesium

Answer 2

D. The mass of the magnesium oxide does not add up to the oxygen and magnesium.

Step-by-step explanation:

The oxygen and magnesium should match the Magnesium Oxide.
