Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon monoxide and hydrogen: C3H3(9)+3 H,O(g)→3 CO(g)+7H,(g) In the second step, carbon monoxide and water react to form hydrogen and carbon dioxide: CO(g)+H,O(g)→H,(9)+CO,(9) Write the net chemical equation for the production of hydrogen from propane and water. Be sure your equation is balanced.

Explain why each of the following chemical equations is not a correct formation reaction:(a) 4 AI(s) + 3 O2(g)→2 AI2O3(s)(b) N2(g) +3/2 H2(g) → NH3(g)(c) 2 Na(s) + O(g) → Na2O(s)

The reaction that was on the screen when you started and its derivative demonstrate that the reaction enthalpy, ΔH, changes sign when a process is reversed. Consider the reaction H2O(l)→H2O(g), ΔH =44.0kJ What will ΔH be for the reaction if it is reversed?

O = rosoft C W There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(1) oxide and sulfur dioxide: 2Cu₂S (s) + 30₂(g) → 2Cu₂0(s) + 2 SO₂ (g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Cu₂O(s) + C(s)→ 2Cu(s) + CO (g) Microsoft O CHEMICAL REACTIONS Reaction sequence stoichiometry Microsoft 6.52.210... esc Suppose the yield of the first step is 64.% and the yield of the second step is 88.%. Calculate the mass of oxygen required to make 2.0 kg of copper. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.
