There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(1) sulfide and oxygen react to form copper(1) oxide and sulfur dioxide: 2 Cu₂S(s)+30₂(9) 2 Cu₂O(s)+2 SO₂(g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Cu₂O(s) + C(s)-2 Cu(s) + CO(g) Write the net chemical equation for the production of copper from copper(1) sulfide, oxygen and carbon. Be sure your equation is balanced.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In the first step, calcium carbide (CaC₂) and water react t form acetylene (C₂H₂) and calcium hydroxide: + Ca(OH)₂ (s) CaC₂ (s) + 2H₂O(g) → C₂H₂(g) 1 In the second step, acetylene (C₂H₂), carbon dioxide and water react to form acrylic acid (CH₂CHCO₂H): 6C₂H₂(g) + 3C0₂(g) + 4H₂O(g) - 5 CH₂CHCO₂H (g) 1 Suppose the yield of the first step is 88.% and the yield of the second step is 86.%. Calculate the mass of calcium carbide required to make 9.0 kg of acrylic acid.

We can use Hess's Law (and some creativity!) to learn about the energetics of reactions that occur in remote environments. Consider the atmospheric reaction, NO + O → NO2 (a) Use the dissociation energy of O2, 498.34 kJ/mol, and the standard heats of formation for NO (+90.25 kJ/mol) and NO2 (+33.18 kJ/mol) to derive the enthalpy change for this reaction.

I know you this question has two parts but it counts as one question. Thank you so much and I hope you have a nice day.
Part 2 The Haber process produces ammonia (NH3) for the chemical industry from nitrogen (N₂) and hydrogen (H₂) as shown in the chemical equation below. This is a reversible reaction. N2 (8) + 3H2(g) → 2NH3 (8) AH = -92 kJ mol-¹ (exothermic) The following questions relate to the effect of changing factors that influence the direction of the above reaction, according to Le Chatelier's principle. For each change in factor (i - iv) listed in the Table, you need to: state the direction of equilibrium, give a reason for your choice, identify if the amount of ammonia produced will increase or decrease. Factor Decrease in concentration of N₂ i) ii) Increase in pressure iii) Increase in temperature iv) A catalyst is added Direction (shift) of equilibrium Scientific explanation for stated direction of equilibrium.

Dry ice is solid carbon dioxide. Instead of melting, solid carbondioxide sublimes according to the equation:CO2(s) ------------>CO2(g) When dry ice is added to warm water, heat from the water causesthe dry ice to sublime more quickly. The evaporating carbon dioxide produces a dense fog often used to create special effects. In a simple dry ice fog machine, dry ice is added to warm water in a Styrofoam cooler. The dryice produces fog until it evaporates away, or until the water gets too cold to sublime the dry ice quickly enough. A small Styrofoam cooler holds15.0 L of water heated to 85°C. Use standard enthalpies of formation to calculate the change in enthalpy for dry ice sublimation, and calculate themass of dry ice that should be added to the water so that the dry ice completely sublimes away when the water reaches 25 °C. Assume no heat loss to the surroundings. (The ∆H°f for CO2(s) is -427.4 kJ/mol.)
