In the following reaction, how much heat is generated when 3.21moles of CH4 are burned

01 04 in the balanced equation for the complete combustion of heptane, the coefficient for carbon dioxide is: Cu + O = CO + HO W

Nitric acid is often manufactured from the atmospheric gases nitrogen and oxygen, and hydrogen prepared by reforming natural gas, in a two-step process. In the first step, nitrogen and hydrogen react to form ammonia: N₂(g) + 3H₂(g) 2 NH, (g) In the second step, ammonia and oxygen react to form nitric acid (HNO3) and water: NH₂ (g) + 20₂(g) → HNO3(g) + H₂O (g) Suppose the yield of the first step is 61.% and the yield of the second step is 77.%. Calculate the mass of nitrogen required to make 10.0 kg of nitric acid. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits. 0 Explanation Check. ☐ x10 8 X 09 0.0 S © 2023 McGraw Hill LLC. All Rights Reserved.

Consider the reaction. heat 2 Al(s) + Fe,O,(s) → Al, O, (s) + 2 Fe(1) If 23.1 kg Al reacts with an excess of Fe, O,, how many kilograms of Al, O, will be produced? mass of Al, 0, produced: kg

The following unbalanced equation illustrates the overall reaction by which the body utilizes glucose to produce energy: C6H12O6(s) + O2(g) → CO2(g) + H2O(l)   What is the conversion factor that allows for the calculation of moles of carbon dioxide based on moles of glucose?

Use the References to access important values if needed for this question. For the following reaction, 4.29 grams of oxygen gas are mixed with excess propane (C3Hg). The reaction yields 2.81 grams of carbon dioxide. (1) What is the theoretical yield of carbon dioxide? (2) What is the percent yield for this reaction? C3Hg (g) +50₂ (g) 3CO₂ (g) + 4H₂O(g) % grams

esc Phosphoric acid, which is commonly used as rust inhibitor, food additive and etching agent for dental and orthopedic use, can be synthesized using a two-step thermal process. In the first step, phosphorus and oxygen react to form diphosphorus pentoxide: P₁(1)+50₂(g) 2 P₂O(g) In the second step, diphosphorus pentoxide and water react to form phosphoric acid: P₂O(g) + 3 H₂O(1)-2 H₂PO₂(0) 4 Write the net chemical equation for the production of phosphoric acid from phosphorus, oxygen and water. Be sure your equation is balanced. 0 Continue 56°F Clear F1 J F2 @ 2 F3 # 3 Q Search F4 $ 4 F5 % 5 F6 6 0-0 X F7 & 00 7 Ś F8 © 2023 McGraw Hill LLC. All Rights Reserved.
