Write the balanced COMPLETE ionic equation for the reaction when Na₂CO₃ and AgNO₃ are mixed in aqueous solution. If no reaction occurs, simply write only NR. Be sure to include the proper phases for all species within the reaction.

If only 0.303 g of Ca(OH)2 dissolves in enough water to give 0.139 L of aqueous solution at a given temperature, what is the Ksp value for calcium hydroxide at this temperature?

Complete the balanced neutralization equation for the reaction below. Be sure to include the proper phases for all species within the reaction. NH4OH(aq) + H3PO4(aq)

Complete the balanced dissociation equation for the compound below in aqueous solution. If the compound does not dissociate, write NR after the reaction arrow. W(ClO4)4 (s)>

The concentration of magnesium ions in seawater is approximately 0.0541 M. To the solution in part 3 above with MgSO4•7H2O (Epsoms Salt), how many more grams of MgCl2•6H2O will you need to use to make 1.0 L of water with the same concentration of magnesium ions as seawater?     (I am reasking this question since the one I posted was never answered, how do I cancel the previous, duplicate question please?)

What mass of NaOHNaOH is needed to precipitate the Cd2+ ions from 30.0mL of 0.500 M Cd(NO3)2 solution?

Write the balanced NET ionic equation for the reaction when aqueous NiCl₂ and aqueous Na₂S are mixed in solution to form solid NiS and aqueous NaCl.

Initial Cu2+ Concentrations of 0.16 M, 0.080 M, 0.040 M, and 0.016 M. 1.00 mL of each solution is in a beaker After the addition of 4.00 mL of 0.5 M NH3 and 3.00 mL of distilled water, based on the dilutions calculate the concentration of Cu2+ in each of the respective beakers

Excess Pb(NO3)2 (aq) is added to 214 mL of a 1.70 mol L-1 solution of NaCl(aq). Assuming complete precipitation, what is the mass of precipitate that forms? Use the course data sheet for any required data. Select the closest answer. 25.3 g 37.4 g 31.4 g 202.3 g 50.6 g

2Fe(s) + 3Cu2+(aq)  2Fe3+(aq) + 3Cu(s) a)Calculate the minimum volume of 1.16M CuSO4 solution that is required to ensure complete reaction of 1.04g of Fe.Since you do not know which reaction will be the one to occur, you must base the calculation on whichever of the equations requires more CuSO4 solution. b)To ensure that sufficient CuSO4 is used, it is common practice to add an excess.Calculate the volume of 1.16M CuSO4 needed to provide a 20% excess in this case.
