A student begins the experiment with a 0.5287 g sample of aluminum can. At the start of week 2, the student determines that 5.0109 g of potassium alum, KAl(SO4)2∙12H2O, were synthesized. What percent yield should the student report? Assume that the aluminum is limiting. Give your answer to four significant figures

Balance the following chemical reaction. Enter the sum of the balanced coefficients as your answer. Assign "blank" coefficients a value of 1. silver iodide + sodium sulfide → silver sul fide + sodium iodide

For the following chemical reaction,                                             N2 (g) + 3 H2 (g) → 2 NH3 (g)  If 15 molecules of nitrogen gas and 12 molecules of hydrogen gas react together what will be left in the container at the end of the reaction.

Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum(IV) bromide solution with aluminium metal. To test this purification process, a student reacted 14.4 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg of platinum metal. From this data, calculate the percent error of this experiment.Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first.Do not show your work in the space provided.Record only your final answer with the correct number of significant digits and the proper units.

[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.

A sample of dry solid waste has the following composition : 531 g carbon (C), 133 g hydrogen (H), and 335 g oxygen(O) . How many liters of air is required to combust the waste.

The actual yield of one of the reactions in 43.5g. What was theoretical yield in the laboratory if the scientist concluded that % yield of the reaction ended up to be 77%.

Relate the model to Chemistry: The balanced chemical reaction for producing water is: 2 H2 + 1 O2 → 2 H2O. Predict which reactant amounts (of the three examples shown below) would get the most water with the least amount of leftovers. Explain how your understanding of Limiting Reactant helped you figure this out.

Assume that your empty crucible weighs 15.98 g, and the crucible plus the sodium bicarbonate sample weighs 18.56 g. After the first heating, your crucible and contents weighs 17.51 g. After the second heating, your crucible and contents weighs 17.50 g. Answer the following questions based on this information.
