Homework Statement Fe2+and Cr2O72- react as follows: 6Fe2+ + Cr2O7 2− + 14H + >>> 6Fe3+ + 2Cr3+ + 7H2O. The equilibrium constant for the reaction is 1×10^57. Calculate the equilibrium concentrations of the iron and chromium species if 10 mL each of 0.02M K2Cr2O7 in 1.14M HCl and 0.12M FeSO4...

ermm..it is 1 mole of KCl = 1 mole of AgCl (0.018-x) mole of KCl = 0.018 mole of AgCl 1 mole of MgCl2 = 2 mole of AgCl 1/2 (0.018-y) mole of MgCl = 0.018 mole of AgCl ?? or 1 mole of KCl = 1 mole of AgCl x mole of KCl = x mole of AgCl 1 mole of MgCl2 = 2 mole of AgCl 1/2y-x mole of MgCl2 =

Thanks you , next time I will show the solution / effort . I'm fairly new here ...

A mixture consisting of KCI and MgCl2 weights 1.2505 g. The mixture was dissolved in water and an excess of AgNO3 was added. The chloride ions were precipitated as AgCl. The mass of AgCl obtained was 2.5788 g. Calculate the percentages of KCI and MgCl2 in the original mixture.

This is the dihybrid cross where the parents are purple ( rrCC ) x white ( RRcc) F1 generation all RrCc(yellow ).The result is F2 generation in the ratio 9:3:4 . (Yellow:white:purple) What kind of gene interaction is this and how should I explain it?

After I have done counting the corn and the result 267 yellow , 97 white , 144 purple ratio 9:3:4 respectively . Recessive - Epitasis ? I have no idea create a inheritance cross and the biochemical influence by genes interaction from this phenomena
