Nazeeh conducted an experiment to demonstrate the law of conservation of matter. He burned a strip of magnesium that had a beginning mass of 5.0 g over an open flame. The magnesium gave off a bright white light and smoke as it was being burned. The white ash that was left over had a mass of 4.5 g. Nazeeh concluded that his experiment did not uphold the law of conservation of matter. What did Nazeeh NOT take into consideration when drawing his conclusion?
A
that some of the mass was lost to the air as light

B
that mass has absolutely no relationship to matter

C
that some of the mass was lost to the air as smoke

D
that ash has a lower mass than the strip of magnesium
