A Mole Ratio

Iron reacts with copper(ll) sulfate in a single replacement reaction. 

By measuring the mass of iron that reacts and the mass of copper metal produced, you can calculate the ratio of moles of reactant to moles of product. This mole ratio can be compared to the ratio found in the balanced chemical equation. 

Which reactant is the limiting reactant How does the experimental mole ratio of Fe to Cu compare with the mole ratio in the balanced chemical equation What is the percent yield  

Prepare all written materials that you will take into the laboratory. Be sure to include safety precautions, procedure notes, and a data table. 

Is it important that you know you are using the hydrated form of copper(II) sulfate Would it be possible to use the anhydrous form Why or why not

The use of an excess of ammonia is home out in practice. A mole ratio of ammonia to ethylene oxide of 10 1 3delds 75 percent monoethanolamine, 21 percent diethanolamine, and 4 percent triethanolamine. Using equimolar proportions under the same reaction conditions, the respective proportions become 12, 23, and 65 percent. 

Diall lated Phenols. 2,4-Di-tert-amjlphenol (2,4-DTAP) or 2,4-bis(l,l-dimethylpropyl)phenol is produced by the alkylation of phenol with isoamylene under acid catalysis in a mole ratio of 2 1 (isoamylene to phenol). The cmde alkylation product contains 4-/ f2 -amylphenol,... 

A 90% yield of isoquinoline (>95% pure) was reported by treating a cmde fraction with hydrochloric acid followed by addition of an alcohoHc solution of cupric chloride in a mole ratio of 1 2 CUCI2/isoquinoline (40). A slighdy lower yield of 2-methylquinoline [91-63-4] (97.5% pure) was obtained from bituminous coal using 30% aqueous urea to form a clathrate (41). 

Manufacture. Chlorinated TSP is made batchwise by addition of a 15% NaOCl solution containing some NaOH to a hot (75—80°C) concentrated Hquor consisting of di- and trisodium phosphates, in a mole ratio of about 1 10, in a suitable reactor, eg, a pan mixer (222). The mixture is allowed to cool slowly under constant agitation until crystallization occurs (62°C). When crystallization is complete, cooling is continued to about 45°C and the slightly moist crystals are air dried. Overdrying can result in decreased stabiHty. 

In a study of the kinetics of the reaction of 1-butanol with acetic acid at 0—120°C, an empirical equation was developed that permits estimation of the value of the rate constant with a deviation of 15.3% from the molar ratio of reactants, catalyst concentration, and temperature (30). This study was conducted usiag sulfuric acid as catalyst with a mole ratio of 1-butanol to acetic acid of 3 19.6, and a catalyst concentration of 0—0.14 wt %. 

The only practicable large-scale method of preparing F2 gas is Moissan s original procedure based on the electrolysis of KF dissolved in anhydrous HF (see however p. 821). Moissan used a mole ratio KF HF of about 1 13, but this has a high vapour pressure of HF and had to be operated at —24°. Electrolyte systems having mole ratios of 1 2 and 1 1 melt at 72° and 240°C respectively and have much lower vapour pressures of HF accordingly... 

Reality Check A mole ratio of 1.00 A 1.00 B 333 C would imply a formula A3B3C10 if the mole ratio were 1.00 A 2.50 B 5.50 C, the formula would be A2B5Cn. In general, multiply through by the smallest whole number that will give integers for all the subscripts. 

Preparation. Anhyd perchloric ac and Ti tetrachloride were combined in a mole ratio of 8 1 at —10° to give a cryst solid whose purity by analysis was 97—8% (Ref 3)... 

Thus, if a mole ratio of about 1 2 1 of S03 to ester is used, the initial reaction gives about 50% conversion of starting material, the products being intermediates I and II. On aging, these intermediates release S03, which reacts with... 

Mass flow measurement has been shown to be efficient as a mole ratio control, even where S03 mass flow was not measurable with sufficient accuracy in the diluted gas stream. 

STRATEGY We convert from the given volume of gas into moles of molecules (by using the molar volume), then into moles of reactant molecules or formula units (by using a mole ratio), and then into the mass of reactant (by using its molar mass). If the molar volume at the stated conditions is not available, then use the ideal gas law to calculate the amount of gas molecules. 

Copolymerization of isopropenylferrocene with styrene was accomplished in two ways. In one method (polymer 16 of Table III) styrene and isopropenylferrocene were mixed together in CH2CI2 at 20°C at a mole ratio of 23/77 of isopropenylferrocene to styrene, and polymerization was initiated with BF3 0Et2. From the 250-MHz NMR spectrum of the product, 27% styrene and 73% isopropenylferrocene units were found to be present in the copolymer, which had an Mu of 2900. This ratio was also confirmed by elemental analysis. 

The volumetric flow rate of the recycle stream is many many times those of the fresh feed and product streams, and the fresh feed and recycle streams are well mixed at the juncture point. If one uses a mole ratio of 3.4 hydrogen to 1 toluene in the fresh feed stream, what fraction of the toluene is converted to benzene under the previously specified conditions The average residence time of a fluid element is 30.1 sec. Explicitly state any assumptions that you make. In order to obtain a numerical answer, a trial and error solution will be necessary. 

Figure 4 shows that the amount of trans-1,4 structure is increased from 557, which is the trans-1,4 content of a polybutadiene prepared with BuLi alone in nonpolar solvents, to a maximum of about 807, trans-1,4 content for polybutadienes prepared at a mole ratio of barium salt to BuLi equal to 0.5. 

Mole Ratio of Ba/Mg at Constant Mg/Al. Figure 10 shows the dependence of the microstructure of polybutadienes on the mole ratio of Ba/Mg with a Mg/Al ratio of 6/1 for polymerizations carried out in cyclohexane at 50°C. The amount of trans-1,4 structure is increased to a maximum of about 907. as the mole ratio of Ba/Mg is decreased from 1.0 to about 0.20. Concurrently, the vinyl content decreased from 77. to 27.. At a mole ratio of 0.05, polymerization was not observed in cyclohexane at 50°C after 3 days. 

Isobutylene recovered from an experiment with a mole ratio of 3 olefins/Cl3SiD contained C—D bonds. This requires that deuteroisobu-tylene was displaced by isobutylene from the complex in a reversible way to lead to equilibrium between olefin molecules in solution and those in the complex. 

Benkeser et al. (55) showed that a mole ratio of 2Cl3SiH to 1-hexyne would react completely in a long time. In 24 hours, a 98% yield of monoadducts had formed. After 111 hours, the same mixture yielded 20% 1,6-and 18% 1,2-bistrichlorosilylhexane. By increasing the concentration of catalyst, the yield of these two diadducts was increased to 44% and 40%, respectively. In this work, 1-trichlorosilyl-1-hexene behaved very much like 1-phenyl-l-hexene, shown in Table VI to form 1,6-diadducts.
