Question

Equal masses of MgO and P4O10 are allowed to form Mg3(PO4)2.Find the excess reagent​?

Answer 1

Answer:

MgO

Explanation:

1. balance the equation

2. stoichiometric coefficient of MgO will be 6 and P4O10 will be 1.

3. assume weight to be w.

4. divide w by their stoichiometric coefficients.

5.smaller value is the Limiting reagent
