A 70. 0 g sample of cesium is sealed in a glass vial and lowered into 250. 0 mL of water at 90. 00 °C. When the cesium had melted, the temperature of the water had dropped to 88. 98 °C. Determine the molar heat of fusion for cesium.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
