Question

work out the empirical formular of 48.6g of mg with oxygen to produce 80.6g magnesium oxide

Answer 1

Answer:

1)Magnesium plus diatomic Oxygen produce Magnesium Oxide.

2) Mg + O2→MgO

3) MgO

....Mg2++O2−

....Crisscrossing will give Mg2O2.

....Since both subscripts are the same, we reduce them to 1, and the correct formula for magnesium oxide is MgO.

4).2Mg + O2→2MgO

5) 2Mg + O2→2MgO

....Both sides have 2 atoms of Mg, and 2 atoms of O. Therefore, matter is conserved.

6) The reactants

....2×Mg=2×24=48 grams

....2×O=2×16=32 grams

....48 + 32=80 g
