Question

Ag + HF..... Al+H2So4 Na2O+H3PO4

Answer 1

1)2Ag + 2HF = 2AgF + H2

2Ag(0)+2H(+) + 2F(-) = 2Ag(+) + 2F(-) + H2(0)

2Ag(0)+2H(+) = 2Ag(+) + H2 (0)

2) 2Al + 3H2SO4 = Al2(SO4)3 + 3H2

2Al(0) + 6H(+) + 3SO4(-2) = 2Al(+3) + 3SO4(-3) + 3H2(0)

2Al(0) +6H(+) = 2Al(+3) + 3H2(0)

3) 3Na2O + 2H3PO4 = 2Na3PO4 +3 H2O

3Na2O + 6H(+) + 2PO4(-3) = 6Na(+) + 2PO4(-3) + 3H2O

3Na2O + 6H(+) =6Na(+) + 3H2O

Answer 2

It seems like you've listed a series of chemical reactions. I'll provide you with the products of these reactions:

1. Ag + HF (Silver + Hydrofluoric Acid):

   • This reaction will produce Silver fluoride (AgF), a white solid, and hydrogen gas (H2) as a byproduct.

2. Al + H2SO4 (Aluminum + Sulfuric Acid):

   • This reaction will produce aluminum sulfate (Al2(SO4)3) and hydrogen gas (H2) as byproducts.

3. Na2O + H3PO4 (Sodium Oxide + Phosphoric Acid):

   • This reaction will produce sodium phosphate (Na3PO4) and water (H2O) as the products.

Please note that these reactions are simplified and do not take into account specific conditions, concentrations, or stoichiometry. In real chemical reactions, the actual products and their quantities may vary depending on the reaction conditions and the stoichiometric ratios of the reactants.
