if you weighed the magnesium ribbon before burning and the magnesium oxide after burning, would the mass afterward be greater, less, or the same????? why???????

The mass would be greater because when you burn the magnesium it combines with oxygen, thus afterwards it weighs the mass of the magnesium plus the mass of the oxygen that combined with it.

That depends if you captured all the product. The magnesium combines with the oxygen in the air so the product should have a greater mass than the original ribbon

The weight will definitely increase.Why?Because the magnesium molecules combine with the oxygen forming Magnesium Oxide ,Mg2O.Oxygen has weight ,as a result, the mass will increase.

It will gain weight. You started off with Magnesium. Now you have Magnesium AND oxygen. The mass will obviously increase.

The mass would be greater.
2Mg + O2 --> 2MgO
The mass of the product would include the mass of the Oxygen that combined with the Magnesium to give you the MgO.

if you're concerning your self, or maybe with if you're no longer, for sure. some thing is accessible. I truly have an exceedingly confusing time understand-how math and Chemistry. To the point that usually I actually imagine that's no longer accessible for me to understand. in case you attitude it with an open options and locate the right individual to describe it even with the actuality that, it helps plenty. easily one of my topics with math... Algebra specially.... I truly have had 3 diverse instructors clarify some thing to me, a similar challenge, slope and stuff. i did not are conscious of it in any respect. A 4th instructor got here to visit even with the actuality that, and he or she develop into in a position to describe it particularly properly and that i understand truly are conscious of it, or maybe as/if a lesson starts coping with it again, with a touch help i believe i'd be in a position to do it. in simple terms because someone has a low IQ or would not understand some thing would not recommend they could't do particular issues. The mind is a muscle, and also you would possibly want to continually exercising it to augment it. A low IQ skill a foul understand-how set and understand-how (i don't understand precisely what IQ checks degree...) each and every thing on the checks might want to be discovered even with the actuality that. you aren't any further born understanding the wisest challenge to do especially circumstances, you in simple terms study that. some human beings keep their minds closed and do not study knowledge and sensual understand-how. someone is likewise no longer born understanding Algebra. that's some thing you should study. Even those with gaining understand-how of disabilities are in a position to study through attempt and time. that's all a count number of ways a lot attempt you're waiting to furnish :) bypass to the Khan Academy internet website. Khan is exceptional :)

it will add weight.
2Mg + O2 = 2MgO
so there is 1 oxygen atom more for 1 mole Mg.

it will be greater becase after burning there will be addtion of oxygen mass.
