Calculate the change in the standard molar entropy of sulfur trioxide gas, SO3, when it is cooled from a temperature of 100 °C to 10 °C at a constant pressure of 1 bar. The standard molar constant-pressure heat capacity of sulfur trioxide is 50.1 J K-1 mol-1.

Which substance is a steroid? cholesterol fatty acid monosaccharide trans fat

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)

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?
