The equations are not balanced. Which equation would have the same coefficients in the same order as 2CO2 + 3H20 C2H6O + 3O2? FeCl3 + NH4OH Fe(OH)3 + NH4Cl
CH4 + O2 CO2 + H2O
Fe + H2SO4 Fe2(SO4)3 + H2
PCl5 + H2O HCl + H3PO4

For lesson: cameras, plant presses, newspaper, paper towels, clip boards, pencils, calculators, field guides, metric measuring tapes, paper, transect squares, colored pencils, ph meters, light meters, computers, etc.for extension: baggies for soil samples collecting, distilled water, hand shovels, beakers, boiled rice, microscopes, well microscope slides or regular microscope slides with cover slips

Caso4(s) < > ca+2 + so4^-2 ksp = [ca+2][so4^-2] = 2.4 x 10^-5 = [0.20][so4^-2] [so4^-2] =1.2 x 10^-4 ag2so4(s) ,> 2ag+ + so4^-2 ksp = [ag+]^2[so4^-2] = 1.5 x 10^-5 = (0.30)^2[so4^-2] [so4^-2] = 1.5 x 10^-5/0.09 = 1.7 x 10^-4 caso4 would precipitate first since it requires less so4^- to form a saturated solution.  i believe this is right, i hope it !  

Ihonestly was looking for an answer not trying to give one

It will be difficult to find the solution
