You are making double-decker sandwiches; each sandwich consists of 3 slices of bread, 2 chicken  slices, and 4 tomato slices.   Suppose that you have 84 slices of bread, 60 chicken slices, and 108 tomato slices.   (a) What is the maximum number of complete sandwiches you can make with the quantities you  have available?   (b) Which ingredient is the limiting one? (Which

[References] nelling salts," which are used to revive someone who has fainted, typically contain ammonium carbonate, (NH4)2 CO3 . Ammon. ponate decomposes readily to form ammonia, carbon dioxide, and water. The strong odor of the ammonia usually restores conscio person who has fainted. The unbalanced equation is (NH4)2 CO3(s) → NH3(9) + CO2(g) + H2O(g) alculate the mass of ammonia gas that is produced if 2.40 g of ammonium carbonate decomposes completely. g NH3 Submit Answer Try Another Version 1 item attempt remaining

What is the total number of oxygen atoms on the right-hand side of this chemical equation? Ca(OH),(s)+CO,(g)→CaCO,(s)+H,0(1)

[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.

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate.Suppose an EPA chemist tests a 250.mL sample of groundwater known to be contaminated with cadmium chloride, which would react with silver nitrate solution like this: CdCl2(aq)+2AgNO3(aq)→2AgCl(s)+CdNO32(aq).  The chemist adds 51.0mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 8.9mg of silver chloride. Calculate the concentration of cadmium chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits.

I only need parts B and D, thank you!   The following quantities are placed in a container: 1.98 × 10^24 atoms of hydrogen, 1.32 mol of sulfur, and 113.8 g of diatomic oxygen. (b) What is the total number of moles of atoms for the three elements? (c) If the mixture of the three elements formed a compound with molecules that contain two hydrogen atoms, onesulfur atom, and four oxygen atoms, which substance is consumed first? (d) How many atoms of each remaining element would remain unreacted in the change described in (c)?

4. In this experiment, ethanol was selected to purify benzoin on Day 1. However, alcohols are inappropriate solvents for recrystallizing compounds containing carboxylic acids. One side reaction is "Esterification" that can occur by placing COOH and OH groups together upon heating. If 3.5 grams of Terephthalic acid and 3 mL methanol undergo esterification, (a) what is the limiting reagent? (b) Predict the grams of the two end products: dimethyl terephthalate and water assuming Esterification is driven to completion. Show calculations. Hint: you can find the grams of methanol through its density.

A chemist invents a new combustion analysis instrument that uses less O2(g) which saves money on each analysis. The improvement is that instead of CO2(g) being formed and trapped, CO(g) is formed and trapped. H2O (g) is also formed and trapped when substances that contain hydrogen are analyzed.(a) The chemist places 2.184 g of an unknown compound of carbon and hydrogen in the new analyzer. 4.627 g of CO (g) and 1.795 g of H2O (g) are produced. Find the empirical formula for the compound.(Molar masses (g/mol): CO = 28.0104, H2O = 18.015) (b) Despite the best efforts of the chemist, the molar mass of the compound cannot be determined (using this method). Clearly explain why this prevents the determination of the molecular formula

Be sure to answer all parts. TCDD, also called dioxin (C H,Cl,O2, molar mass 322.0 g/mol), is a potent poison. The average lethal dose in humans is estimated to be 3.0 x 10- mg per kg of body weight. (a) How many grams constitute a lethal dose for a 91-kg individual? (b) How many molecules of TCDD does this correspond to? (a) X 10 g dioxin (b) x 10 molecules

The sample is analyzed and found to contain three elements, C, H and O. A 2.147 g sample of the compounds burns in O2(g) to produce 4.297 g of CO2(g) and 1.757 g of H2O(g). (a) Calculate the moles of C in the sample. (b) Calculate the moles of H in the sample. (c) Calculate the moles of O in the sample. (d) Determine the empirical formula for the compound.
