When magnesium burns in air, a white flaky ash of magnesium oxide is produced. is the mass of magnesium oxide greater than, less than, or the same as the original piece of magnesium?

The mass of magnesium oxide is greater than the mass of original piece of magnesium.

Explanation:

When magnesium burns in air to form a white flaky ash of magnesium oxide, it is undergoing a combination reaction.

A combination reaction is defined as the chemical reaction in which two lighter substances combine to form a single larger substance.

The chemical equation for the formation of magnesium oxide follows:

Hence, the mass of magnesium oxide is greater than the mass of original piece of magnesium.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
