the equation for the fermentation of glucose to alcohol is C6H12O6 --> C2H5OH+2CO2 DeltaH°= -67kJ Calculate the enthalpy change when 1.0 g of glucose (C6H12O6) reacts.
Ethyl chloride is prepared by the reaction of chlorine with ethane according to the following balanced equation. C2H6(g) + Cl2(g) -----> C2H5Cl(l) + HCl(g) When 5.6 g of ethane is reacted with excess chlorine, 8.8 g of ethyl chloride forms. Calculate the percent yield of ethyl chloride. Percent yield of ethyl chloride = _____%
1. Why do yeasts perform alcohol fermentation? 2. What is the chemical reaction for fermentation? 3. Which are the reactants in this reaction? Which are the products? 4. What is the gas that accumulates in the bag, causing it to inflate? In addition to this gas, what is another product of this process? Can you think of one example when either of these products is useful during cooking/baking? 5. How does inflation of the bag correlate with the amount of...
To make beer, yeast converts glucose (C6H12O6) into ethanol (� = 0.789 g/mL) in a process called fermentation. The unbalanced reaction is written here: _____C6H12O6 (aq) → _____C2H5OH (l) + _____CO2 (g) If 200.0 g of glucose yields 100.0 mL of ethanol, what is the % yield for the reaction? Baking soda (NaHCO3) can be made by the following reaction: NaCl (aq) + NH3 (aq) + CO2 (aq) + H2O (l) → NaHCO3 (s) + NH4Cl (aq) If 7.77 g...

Answer the following questions about the fermentation of glucose (C6H12O6 , molar mass 180.2 g/mol) to ethanol (C2H6O) and CO2. C6H12O6(s) → 2 C2H6O(l) + 2 CO2(g) Δ H = −16 kcal/mol glucose ethanol How many kilocalories of energy are released from 54.0 g of glucose?
When 8.42 g of B2H9 reacts with 27.8 g O2 according to the equation : 2B2H9 + 12O2 → 5B2O3 + 9H2O 8.24 g H2O forms. What is the percent yield for the reaction.
If 4.46 g of acetic acid and 2.19 g of isopentyl alcohol are used in the reaction, what is the limiting reagent? What is the theoretical yield? What is the percent yield if 2.50 g of isopentyl acetate are obtained? (please show all calculations!!!)
One type of breathalyzer employs a fuel cell to measure the quantity of alcohol in the breath. When a suspect blows into the breathalyzer, ethyl alcohol is oxidized to acetic acid at the anode: CH3CH2OH(g)+4OH−(aq)→HC2H3O2(g)+3H2O(l)+4e− At the cathode, oxygen is reduced: O2(g)+2H2O(l)+4e−→4OH−(aq) The overall reaction is the oxidation of ethyl alcohol to acetic acid and water. When a suspected drunk driver blows 185 mL of his breath through this breathalyzer, the breathalyzer produces an average of 325 mA of current...
