Answer 1

2H₃PO₄+3CuO=Cu₃(PO₄)₂+3H₂O
P₂O₅+3BaO=Ba₃(PO₄)₂
2H₃PO₄+3Na₂SO₄=3H₂SO₄+2Na₃PO₄
P₂O₅+6NaOH=2Na₃PO₄+3H₂O
H₃PO₄+KOH=K₃PO₄+2H₂O
H₂SO₄+P₂O₅=HPO₃+SO₃

Answer 2

Balancing the Equations

Let's balance the given chemical equations one by one:

1. H3PO4 + CuO = P2O5 + BaO

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

2H3PO4 + 3CuO = P2O5 + 3BaO 2. H3PO4 + Na2SO3 = P2O5 + NaOH

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

2H3PO4 + 3Na2SO3 = P2O5 + 6NaOH 3. H3PO4 + KOH = H2SO4 + P2O5

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

2H3PO4 + 3KOH = H2SO4 + P2O5 4. H2SO4 + P2O5 = ?

The equation H2SO4 + P2O5 is not balanced. To balance it, we need to know the products formed. Could you please provide the products for this equation?
