Add of distilled water at room temperature to a clean test tube and add a spoonful of sodium thiosulfate pentahydrate . Stopper the test tube and shake . If all the crystals dissolve add one more spoonful and shake again. Using the terms SATURATED or UNSATURATED , describe this solution. Keep this for procedure 10. If you added additional sodium thiosulfate solid to this mixture would you expect it to dissolve ? Explain .

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

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.
