Acetylene gas (c2h2) used in welding, pro- duces an extremely hot flame when it burns in pure oxygen according to the reaction
2 c2h2(g)+5 o2(g) −→ 4 co2(g)+2 h2o(g) .
how much co2 is produced when 2 g of c2h2 burns completely?

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?
