A number of chemical reactions have been proposed for the formation of organic (chemicals of life) compounds from inorganic precursors. Here is one of them: H2S(g) + FeS(s) + CO2(g) → FeS2(s) + HCO2H(l) a) identify the ions and charges in FeS and FeS2 and name the compounds b) How much HCO2H is obtained by reacting 1.10 g of FeS with 0.500 g H2S and 0.500 g of CO2 if the reaction produces a yield of 50%?

The enthalpy change for a chemical reaction is the sum of the energy consumed in breaking bonds and the energy released during bond formation. One way to determine the overall energy change for a chemical reaction is to apply Hess's law to add together a group of reactions which can be arranged such that the chemical equations, when combined, give the overall equation we are trying to characterize 3rd attempt See Hint Ad See Periodic Table Part 1 (1 point)...
