During an investigation a scientist heated 27 g of mercuric oxide till it decomposed to leave a dry product. The total mass of the product formed was 25 g. Does the law of conservation of mass hold true in this case? Use complete sentences to justify your answer based on numerical calculations.
Answer: Yes, the law of conservation of mass is true because even though some/2grames of mass was not there to end the 2 grams might have evaporated or escaped.
Explanation:
I got this right on flvs and more explanation is up there kinda. hope this helps.
Even though two grams seemed to disappear or vanish, the law of conversation of mass still holds true. Mercuric oxide, when heated, forms a gas of mercury and oxygen. During the investigation, some gas could have escaped or evaporated.
