InterviewSolution

1.	Magnesium and Oxygen combine in the ratio of 3:2 by mass to form magnesium oxide. How much oxygen is required to react completely with 12 g of magnesium.
Answer» Solution :Magnesium (Mg( and oxygen (O) COMBINE in the RATIO =3:2 to form compound magnesium oxide (Mgo), it follows LAW of constants properties, 3g of Mg combines with =2g of O Therefore 12G of Mg combinaes with `2x12//3=8` of oxygen
