Make up the reaction equations according to the following data: 1) sodium phosphate, formed by dissolving sodium in acid, was isolated from the solution 2) in industry, ferrous sulfate is obtained as a by-product at metalworking plants
1) 6Na + 2H3PO4 = 2Na3PO4 + 3H2 (gas, up arrow)
Na3PO4 + 3AgNO3 = Ag3PO4 (precipitate, down arrow) + 3NaNO3
2) Fe + H2SO4 = FeSO4 + H2 (gas, up arrow)
