Answer 1

1)Ba+2H2O=Ba(OH)2+H2; 2) 2NaOH+H2SO4=Na2SO4+2H2O; 3) 2H3PO4+3Ba(OH)2=Ba3(PO4)2+6H2O; 4)P2O5+3H2O=2H3PO4; 5) 3BA+2P=Ba3P2; 6) 2Al+3Br=Al2Br3; 7) 2Mg+O2=2MgO; 8) 6K+N2=2K3N.

Answer 2

Equation 1: Barium + Water = Barium Hydroxide + Hydrogen

The balanced equation for the reaction between barium and water to form barium hydroxide and hydrogen is as follows:

Ba + 2H2O → Ba(OH)2 + H2 [[1]]

Equation 2: Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water

The balanced equation for the reaction between sodium hydroxide and sulfuric acid to form sodium sulfate and water is as follows:

2NaOH + H2SO4 → Na2SO4 + 2H2O [[2]]

Equation 3: Phosphoric Acid + Barium Hydroxide = Barium Phosphate + Water

The balanced equation for the reaction between phosphoric acid and barium hydroxide to form barium phosphate and water is as follows:

3H3PO4 + 4Ba(OH)2 → Ba3(PO4)2 + 6H2O [[3]]

Equation 4: Phosphorus Pentoxide + Water = Phosphoric Acid

The balanced equation for the reaction between phosphorus pentoxide and water to form phosphoric acid is as follows:

P4O10 + 6H2O → 4H3PO4 [[4]]

Equation 5: Barium + Phosphorus = Barium Phosphide

The balanced equation for the reaction between barium and phosphorus to form barium phosphide is as follows:

3Ba + 2P → Ba3P2 [[5]]

Equation 6: Aluminum + Bromine = Aluminum Bromide

The balanced equation for the reaction between aluminum and bromine to form aluminum bromide is as follows:

2Al + 3Br2 → 2AlBr3 [[6]]

Equation 7: Magnesium + Oxygen = Magnesium Oxide

The balanced equation for the reaction between magnesium and oxygen to form magnesium oxide is as follows:

2Mg + O2 → 2MgO [[7]]

Equation 8: Potassium + Nitrogen = Potassium Nitride

The balanced equation for the reaction between potassium and nitrogen to form potassium nitride is as follows:

3K + N2 → 2K3N [[8]]
