Unformatted text preview: constant? Because in the experiment the only change is in the amount of sulfur, the amount of copper is unaffected by the heat. 4. Are your results for the two heating steps identical? Why? No they are not identical because of the fractional uncertainties. There may have been errors in measurement. 5. What would be the effect if all of the copper reacted but enough oxygen was present to form copper (II) oxide? There would not be much of an effect. 6. What would be the effect on your results if some of the copper remained unreacted? The mass would not be the same and therefore the copper and sulfur would not be in proportion. 7. Using your results, calculate the empirical formula of copper sulfur compound. Cu2S...
