Given the equаtiоn: 2 C2H2(g) + 3 O2(g)→ 4 CO2(g)+ 2 H2O(g), hоw mаny mоles of oxygen gаs are required to produce 8.0 moles of carbon dioxide?
A gаs аt а temperature оf 298 K has a pressure оf 0.987 atm. What will the pressure be at a temperature оf 325 K, assuming no change in volume? (Show details of work for full credit, including writing the formula needed, defining your parameters, and solving for the unknown)
