Consider the synthesis of ammonia: N2 (g) +3H, (g) 2NH3 (g)

The extraction of aluminum metal from the aluminum hydroxide found in bauxite by the Hall-Héroult process is one of the most remarkable success stories of 19th century chemistry, turning aluminum from a rare and precious metal into the cheap commodity it is today. In the first step, aluminum hydroxide reacts to form alumina Al2O3  and water:   2Al(OH)3(s) + Al2O3(s) ->  3H2O(g) In the second step, alumina Al2O3  and carbon react to form aluminum and carbon dioxide:   2Al2O3(s) +  3C(s) + 4Al(s) ->  3CO2(g) Suppose the yield of the first step is 74.%  and the yield of the second step is  76.% . Calculate the mass of aluminum hydroxide required to make  4.0kg  of aluminum.   Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

Suppose a pair of chemical compounds A and B can react in two different ways: A+B C Reaction 1 gives product C. A+B D →> Reaction 2 gives product D. The following facts are known about the two reactions: • Reaction 1 is endothermic and Reaction 2 is exothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For if one energy is less than another, that fact should be clear in your sketch. energy A + B Reaction 1 reaction coordinate energy A + B Reaction 2 reaction coordinate ☑

Which reaction has the largest AS? ON₂(g) + 3H₂(g) → 2NH3(9) □2NO(g) → N₂O2(g) O2N₂ H₁(g) →→→ 2NH3(g) + H₂(g) □ O₂(g) + 2H₂(g) → 2H₂O(g) □ O2(g) +2H₂(g) → 2H₂O(l)

Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s)+O2(g)→2CO(g)   In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:   Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)   Write the net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide. Be sure your equation is balanced.

Balance the following chemical equation (if necessary): C₃H₆(g)+O₂(g)→CO₂(g)+H₂O(g)

Consider the following reactions:CoO (s) + CO (g) D CO2 (g) + Co (s) Kc(1) = 490.2 CoO (s) + 2 H2 (g) D 2 Co (s) + 2 H2O (g) Kc(2) = 4.5 x 103a. Write the overall equation for the reaction of hydrogen gas and carbon dioxide gas to produce carbon monoxide gas and steam.
