how do i do this?
g. Iron(III) phosphate, FePO4 the basis of the general solubility rules (Table 7.1 in Zumdahl or Figure 7.7 in Tro) write a Balanced Molecular Equation for the precipitation reactions that take place when the following aqueous solutions are mixed. You must ensure that the elements/ions making up the products are combine in the correct proportions. Additionally, you must include the physical state of each compound {ie (aq) or (g) or (s) or (I)}. If no...

A student obtained a vial of powder consisting of a mixture of iron (III) chloride hexahydrate (FeCl_3-6H_2O) and silver nitrate (AgNO_3) in unknown proportions. He weighed the vial with the powder in it and found the mass to be 20.560 g. He then poured the powder into a beaker and found the mass of the empty vial to be 15.723 g. Water was added (500 mL) to powder in the beaker, and the contents were mixed and heated for 15...

10.0 g of alloy containing only Fe, Cr and Ni when heated with dil. HNO3 dissolved to give Fe3+, Cr3+ and Ni2+ respectively. The resulting solution was diluted to a total volume of 250.00 cm3 by adding distilled water. 25.00cm3 of the diluted solution was treated with excess NaOH and H2 O2 . The obtained precipitate P was fltered and yellow colour fltrate Q was acidifed with dil. H2 SO4 acid, and titrated with 1.0mol dm-3 Fe2+ solution. The volume...
