Urgent ! 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.
sorry guy I not know the answer but please follow me
yes, law of conservation of mass hold true here
27g of mercuric oxide heated and only 25g of dry material produced .
formula of mercuric oxide is= Hgo
there is left 25g dry matter and 2g of material is evaporate and it is present in vapour form.
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.
I got this right on flvs and more explanation is up there kinda. hope this helps
atomic number of carbon is 6
electronic configuration of carbon is 1s²2s²2p²
orbital diagram of carbon is as shown here in the image.
