Final answer:
The correct answer is d) 2K₂PO₄ + 3MgO → Mg₃(PO₄)₂ + 2K₂O. In this balanced chemical equation, 2 molecules of potassium phosphate react with 3 molecules of magnesium oxide to produce 1 molecule of magnesium phosphate and 2 molecules of potassium oxide.
Step-by-step explanation:
The correct answer is d) 2tK₂tPO₄ + 3tMgO → tMg₃(tPO₄)₂ + 2tK₂tO.
In this balanced chemical equation, we can see that 2 molecules of potassium phosphate (K₂PO₄) react with 3 molecules of magnesium oxide (MgO) to produce 1 molecule of magnesium phosphate (Mg₃(PO₄)₂) and 2 molecules of potassium oxide (K₂O).
It's important to note that the subscripts in the chemical formula are not represented with a t. They indicate the number of atoms in each molecule or formula unit.
