Name three possible sources of error in a calorimetry experiment

Chemistry Lecture Notes 9/29/16 Water Properties Properties Liquid at room temperature Ice is less dense than liquid water High density, especially for its molecule size High Heat capacity High Vaporization Universal Solvent Atoms Molecule-chemically bonded, atoms are mostly empty space Valance electrons-electrons in the outermost shell of an atom (ex. Oxygen has 6 valence electrons) Core electrons-electrons in the innermost shell (oxygen has 2 core electrons) Lewis Symbols-a visual representation of valence electrons a s dots around the element symbol Noble gasses were stable and did not react to other elemen ts, theory is that having 8 electrons as a valence shell makes them nonreactive Octet rules-atoms tend to gain or lose share electro
