- What is Hrxn for reaction of iron(III) oxide and carbon monoxide to give iron metal and carbon dioxide gas? Use the following reactions: 4Fe(s)+3O2(g)2Fe2O3(s)H=1648.4kJ4CO(g)+O2(g)2CO3(g)H=565.98kJarrow_forwardEthanol, C2H5OH, is a gasoline additive that can be produced by fermentation of glucose. C6H12O62C2H5OH+2CO2 (a) Calculate the mass (g) of ethanol produced by the fermentation of 1.000 lb glucose. (b) Gasohol is a mixture of 10.00 mL ethanol per 90.00 mL gasoline. Calculate the mass (in g) of glucose required to produce the ethanol in 1.00 gal gasohol. Density of ethanol = 0.785 g/mL. (c) By 2022, the U. S. Energy Independence and Security Act calls for annual production of 3.6 1010 gal of ethanol, no more than 40% of it produced by fermentation of corn. Fermentation of 1 ton (2.2 103 lb) of corn yields approximately 106 gal of ethanol. The average corn yield in the United States is about 2.1 105 lb per 1.0 105 m2. Calculate the acreage (in m2) required to raise corn solely for ethanol production in 2022 in the United States.arrow_forwardOne of the few industrial-scale processes that produce organic compounds electrochemically is used by the Monsanto Company to produce1,4-dicyanobutane. The reduction reaction is 2CH2CHCH+2H++2eNC(CH2)4CN The NC(CH2)4CN is then chemically reduced using hydrogen gas to H2N(CH2)6NH2, which is used in the production of nylon. What current must be used to produce 150.kg NC(CH2)4CN per hour?arrow_forward
- Based on the submicroscopic representation, what is the balanced chemical reaction for this process? = N = H O 6 N2(g) + 9 H2(g) → 6 NH3(g) 3 N2(g) + 9 H2(g) → 6 NH3(g) O N2(g) + H2(g) → NH3(g) 6 N2(g) + 9 H,(g) → 6 NH3(g) + 3 N2(g) O 2 N2(g) + 3 H2(g) → 3 NH3(g) O N2(g) + 3 H2(g) → 2 NH3(g)arrow_forwardClassify each chemical reaction: KOH(aq) + HBrO (aq) reaction K BrO (aq) + H₂O (1) Na Cl (aq) + AgNO3(aq) → NaNO3(aq) + Ag Cl (s) 16K (s) + S₂ (s)→ 8K₂S (s) 2CH₂CH₂CO₂H (1) + 70₂(g) → 6CO₂(g) + 6H₂O(g) ✓ 6 ✓ 7 type of reaction (check all that apply) combination single replacement double replacement decomposition combination single replacement double replacement decomposition combination single replacement double replacement decomposition combination single replacement double replacement decomposition ✓8 X precipitation combustion acid-base precipitation combustion acid-base precipitation combustion acid-base precipitation combustion acid-base 9 10arrow_forwardFor each chemical reaction listed in the table below, decide whether the highlighted atom is being oxidized or reduced. reaction 2H,S(q)+O,(9) → 2S(s)+2H,O NH₂(aq) +20₂(g) → HNO₂(aq) + H₂O(1) 1 FeO(s)+CO(g) → Fe(s) + CO₂(9) CO(9)+H₂O(g) → CO₂(9)+ H₂(9) highlighted atom is being.... oxidized O O O reduced O O O neither oxidized nor reduced O O Oarrow_forward
