Answer» MG is burnt with 0.56g O2 in a closed vessel. Which reagent is LEFT in excess and how much?First of all write a balance Rxn2Mg +o2 →→2 MgoNow 2 moles of mg REACT with 1 mole of oxygen32 gm oxygen react with 48 gm of mgApply UNITARY method32 gm o2 …….reacts with 48 gm mg1gm of o2 will react ……..48／32So,0.56 gm o2 will react ……..48×0.56/32=0.84 gm magnesium .This is the amount of mg that have been consume or react with oxygen …..so ,left amount1–0.84=0.16Hope it Helps For Quick Help in 5 Hours Follow Me
