Be sure to answer all parts. Fermentation is a complex chemical process of wine making in which glucose is converted into ethanol and carbon dioxide: C,H1206 → 2C,H;OH + 2CO2 glucose ethanol Starting with 805.6 g of glucose, what is the maximum amount of ethanol in grams and in liters that can be obtained by this process (density of ethanol = 0.789 g/mL)? g L

In the earth's primitive atmosphere, it is thought that water could have reacted with methane to produce hydrogen gas and carbon monoxide. CH(g) + H;O(g) → CO(g)+ 3H2(g) The particulate representation to the right shows a product mixture for the hydrogen forming reaction above. Which species is the limiting reactant? A. CH,(g) В. Н.О(g) C. Co(g) D. H,(g) E. It is a stoichiometric mixture

(b) An unknown mass of Na3PO4(s) is dissolved in water to form 50.00 mL of solution. This is Solution A. Then 10.00 mL of Solution A is diluted with water to 50.00 mL. The final solution is Solution B. 20.00 mL of Solution B contains 4.408 x 1020 sodium ions. (NA = 6.022 x 1023 mol-1) Calculate the mass of Na3PO4(s) that was dissolved to form Solution A.

A 0.9 g sample of a mixture of KCl and MgCl2 is treated with excess AgNO3(aq). If 2.37 grams of AgCl(s) are obtained, then what is the percentage by mass of KCl in the original mixture? Your answer must be accurate to two significant digits. Keep several extra digits in your calculations and round off only at the end. Do not include the percent sign (%) as part of your answer.   Molar masses (in g mol−1): KCl, 74.55 MgCl2, 95.21 AgCl, 143.35

Part a) When FeS3 • 2H2O is heated, it gives off water, SO2 and Fe2O3. Is this a chemical or physical change? When CuSO4 • 5H2O is heated, it gives off water and CuSO4. Is this a chemical or physical change? Which of these changes can be easily reversed? Part b) Is the molar ratio of the products is different from the molar ratio in the hydrate formula, has a chemical or physical change taken place?

Sulfuric acid dissolves aluminum metal according to the following reaction: 2Al(s)+3H2SO4(aq)→Al2(SO4)3(aq)+3H2(g) Suppose you wanted to dissolve an aluminum block with a mass of 15.6 g . a) What minimum mass of H2SO4 would you need? Express your answer in grams. b)What mass of H2 gas would be produced by the complete reaction of the aluminum block?Express your answer in grams.

Cobalt(II) chloride forms several hydrates with the general formula CoCl2 ·x H2O , where  x  is an integer. If the hydrate is heated, the water can be driven off, leaving pure  CoCl2  behind.   Suppose a sample of a certain hydrate is heated until all the water is removed, and it's found that the mass of the sample decreases by 22.% . Which hydrate is it? That is, what is  x ?

Morphine (C₁₇H₁₉NO₃) is a painkiller in the opiate family. A sample of morphine was discovered that had been diluted by mixing with table salt (sodium chloride). When 2.00 g of the mixture undergoes combustion, 3.97 g of CO₂ is produced. What is the mass percent of morphine in the mixture?

Alcoholic fermentation converts glucose (C6H12O6) into ethanol (C2H5OH) and carbon dioxide (CO2). What mass of carbon dioxide can be formed from the alcoholic fermentation of 25.4 g of glucose?

When ammonia is mixed with hydrogen chloride (HCl), the white solid ammonium chloride (NH4Cl) is produced. Suppose 10.0 g ammonia is mixed with the same mass of hydrogen chloride. What substances will be present after the reaction has gone to completion, and what will theirmasses be?
