The combustion of ethane ( c 2 h 6 ) (c2h6) produces carbon dioxide and steam. 2 c 2 h 6 ( g ) + 7 o 2 ( g ) ⟶ 4 co 2 ( g ) + 6 h 2 o ( g ) 2c2h6(g)+7o2(g)⟶4co2(g)+6h2o(g) how many moles of co 2 co2 are produced when 5.80 mol 5.80 mol of ethane is burned in an excess of oxygen?

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

Which of these conditions most likely produces an unstable isotope?
