Sulfurous acid is unstable in aqueous solution and gradually decomposes to water and sulfur dioxide gas (which explains the choking odor associated with sulfurous acid solutions). H2SO3(aq) → H2O(l) + SO2(g) If 4.05 g of sulfurous acid undergoes this reaction, what mass of sulfur dioxide is released?

For the following reaction, 6.80 grams of water are mixed with excess chlorine gas. The reaction yields 15.1 grams of hydrochloric acid. chlorine (g) + water (1) →→→→hydrochloric acid (aq) + chloric acid (HCIO3) (aq) What is the theoretical yield of hydrochloric acid ? || What is the percent yield of hydrochloric acid ? grams %

Consider the reaction of solid P, and chlorine gas to form gaseous phosphorus trichloride. a) Write the balanced chemical equation for the reaction. b) The balanced chemical equation is P,(s) + 6 CI,(g) → 4 PCI,(g). What is the mass in grams of phosphorus trichloride that can be formed from 222.3 grams of P, based on the balanced chemical equation? c) The balanced chemical equation is P,(s) + 6 CI,(g) → 4 PCI,(g). What is the mass in grams of phosphorus trichloride that can be formed from 304.8 grams of chlorine gas based on the balanced chemical equation? 28 d) Given that 222.3 grams of P, react to make 985.6 g of PCI, and 304.8 g of CI, react to make 393.5 g of PCI, which reactant is limiting? e) The theoretical yield for the reaction is 393.5 g of PCI,. If only 218.7 g of phosphorus trichloride were collected, what is the percent yield of the reaction?

[Tutorial: Limiting reactant stoichiometry] This question will walk you through the steps of calculating the mass of products produced based on your determination of the limiting reactant.   b) Step 2a: Use dimensional analysis to determine the theoretical yield of the product. Calculate the theoretical yield in grams Al₂O₃ from the complete reaction of 64.7 grams Al according to the following balanced chemical equation: 2 Al(s) + Fe₂O₃(s) → Al₂O₃(s) + 2 Fe(s) c) Calculate the theoretical yield in grams Al₂O₃ from the complete reaction of 201 grams Fe₂O₃ according to the following balanced chemical equation: 2 Al(s) + Fe₂O₃(s) → Al₂O₃(s) + 2 Fe(s) d) Which of the following substances is the limiting reactant? e) What is the mass in grams of the excess Fe₂O₃ remaining after the partial reaction of 201 g Fe₂O₃ with 64.7 g Al? Give your answer to three significant figures.
