5. Generally, in order to do a stoichiometry problem, you need a complete balanced equation. However, in some cases it is possible to do some stoichiometric calculations without the complete equation as long as a particular element is present in only one reactant and one product. For example, if you were told that an experiment converted FeCl3 to Fe3O4 and that those were the only reactants and products that contained iron (Fe), you would know that there would have to be 3 moles of FeCl3 for every 1 mole of Fe;O4 or else the iron would not balance. You would not know for sure whether the balancing coefficients were actually 3 and 1 (They might be 6 and 2, 9 and 3, 12 and 4, etc) but you would know that they had to be in a 3 to 1 ratio and that would be enough to relate those two compounds with the correct stoichiometry. a) In Part I of your experiment, potassium carbonate (K,CO3) was the only reactant which contained carbon (C) and strontium carbonate (SrCO3) was the only product…
