- How many carbon monoxide molecules (CO) are needed to react with 8 hydrogen molecules (H2) to produce methyl alcohol molecules (CH3OH)?arrow_forwardHeptane, C7H16, can be catalytically reformed to make toluene, C6H5CH3, another seven-carbon molecule. How many hydrogen molecules are produced for every toluene molecule derived from heptane? Write a balanced chemical equation for this reaction. Why is it profitable to convert heptane into toluene?arrow_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_forward
- Approximately 12 billion kilograms of phosphoric acid (H3PO4) are produced annually for fertilizers, detergents, and agents for water treatment. Phosphoric acid can be prepared by heating the mineral fluoroapatite (Ca5(PO4)3F) with sulphuric acid in the presence of water. Ca5(PO4)3F + 5H2SO4 + 10H20 → 3H3PO4 + 5CaSO4 2H20 + HF If every kilogram of fluoroapatite yields 390 g of phosphoric acid, what is the percent yield? percentarrow_forwardNitroglycerin, a very unstable compound (molecular structure shown below), is a liquid at room temperature. When heated to 218.0°C or subjected to shock, it rapidly decomposes into four different gases. Liquid nitroglycerin has a density of approximately 1.60 g/mL. The nitroglycerin decomposition reaction equation is: 4 C3H5N3O9 (1)→ 12 CO₂(g) + 10 H₂O(g) + 6 N₂(g) + O₂(g) Assume that when heated to 218.0°C, 1.00 lb of nitroglycerin explodes heating the product gases to 750.0°C. Determine the total gas volume, in L, produced by the explosion.

Burning hydrocarbons in the presence of oxygen, O2, produces carbon She oxide, CO₂, and water, H₂O. Methane, CH4, is a hydrocarbon used primarily as fuel to make heat and light. The overall reaction of a number of such steps of methane gas is: CH4(g) + O2(g) + NO(g) → CO2(g) + H2O(g) + NO2(g) + OH(g) Suppose that 3.92 L of methane at STP, 10.8 L of oxygen at STP, and 8.3 L of nitrogen monoxide at STP were combined in a 7.0 L flask.
