Carbon disulfide (CS2 ) boils at 46.30 oC and has a density of 1.261 g/mL. When 0.260 mol of a nondissociating solute is dissolved in 410.0 mL of CS2, the solution boils at 47.48 oC. What is the molal boiling-point-elevation constant for CS2

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

fe 55.85 g/mol and h2o 18.02 g/mol.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
