What is the net ionic equation for a reaction between AgNO3(aq) and K2SO4(aq)

Balance the following chemical equation (if necessary): FeCl₃(aq) + Na₂S(aq) → Fe₂S₃(s) + NaCl(aq)

The iron content of iron ore can be determined by titration with K₂Cr₂O₇ according to the equation 14H⁺(aq) + Cr₂O₇²⁻(aq) + 6Fe²⁺(aq) → 6Fe³⁺(aq) + 2Cr³⁺(aq) + 7H₂O(l) Diphenyl amine is used as an indicator as it changes color from green to purple when the endpoint is reached. A sample of iron ore with a mass of 3.255 g was dissolved with HCl and then treated with a reducing agent to convert any Fe³⁺ in the ore to Fe²⁺. Titration with 0.0645 M K₂Cr₂O₇ solution required 45.65 mL of the solution to reach the endpoint. The molar mass of Fe is 55.85 g/mol. Calculate the mass percent iron in the ore.

Use the following balanced chemical equation to answer the below question: 2H&PO4 (aq) +3Mg(OH)2 (aq) 6H2O m + Mg3(PO4)2 (s) The titration of a 14.0 mL sample of H3PO, requires 3.51 mL of 0.400 M Mg(OH)2 to reach the equivalence point. What is the concentration of H3PO,?

Complete and balance the following equations. MnO4−(aq)+CH3OH(aq)→Mn2+(aq)+HCO2H(aq) (acidic solution)

What type of chemical reaction is illustrated in the following FeBr3(aq) + AgNO3(aq) = Fe(NO3)3(aq) + AgBr(s)
