What is the full equation (not the net ionic equation) for the chemical reaction of 0.001 M Fe(NO3)3 plus 0.0002 M NaSCN diluted up to 10 mL with 0.1M HNO3? Please include the acid that is the diluent.

A 25.00 mL aliquot is withdrawn from the liquid portion of saturated Manganese (II) hydroxide and transferred to an Erlenmeyer flask.  After the addition of methyl orange, a titration with 0.0045 M HCl was performed.  The endpoint was reached after 8.72 mL of the acid was added.   What is the balanced chemical equation? How many moles of hydroxide ions were neutralized in the reaction?  What is the molar concentration of hydroxide in the saturated solution?  What is the molar concentration of Magnesium ion in solution?

1.50 mL of 0.15M Fe2(SO4)3 is diluted with deionized water to 25.00 mL in a volumetric flask. What is the concentration (molarity) of iron (not Fe2(SO4)3) in the diluted sample?

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.

A solution of malonic acid (H2C3H2O4) with a known concentration of 0.500 M H2C3H2O4 is tirated with a 0.255 M KOH solution. How many mL of KOH are required to reach the second equivalence point with a starting volume of 60.0 mL H2C3H2O4, according to the following balanced chemical equation: H2C3H2O4 + 2 KOH---> K2C3H2O4 + 2 H2O
