When barium iodide (Balz) is dissolved in water, the temperature decreases. Which of the following is true?
Water is the solute, barium iodide is the solvent, and the process is exothermic.
O Barium iodide is the solute, water is the solvent, and the process is exothermic
Barium iodide is the solute, water is the solvent and the process is endothermic
O Water is the solute, barium iodide is the solvent, and the process is endothermic.

a chemical reaction

explanation:

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.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

answer; 4 electrons;
