Free Respоnse 2 A smаll аmоunt оf rubidium bromide (RbBr) is dissolved in а large amount of water. After mixing, the resulting solution is colorless (none of the white crystalline solid remains, and the solution is transparent and not cloudy) and the temperature of the solution decreases.   A. At the atomic-molecular level, draw what you think the separate RbBr and H2O samples look like before mixing.  Make sure you include what all components of your drawing represent.  Indicate and label the strongest interactions present for each sample.              RbBr                                                                 H2O   B. At the atomic-molecular level, draw what you think the RbBr and H2O look like after they are mixed. Make sure you include what all components of your drawing represent.  Indicate and label the strongest interactions present after they are mixed.     C. Based on the information provided in Part A, the enthalpy of the solution ΔHsoln is (Positive   or    Negative) when RbBr dissolves in water.(This is your claim.)   D. Based on your answers from Parts A-B, list the bonds and/or interactions that are overcome in the solute (RbBr) and solvent (H2O) and formed in the dissolution process (RbBr and H2O solution). (This is your evidence.) Overcome:   Formed:   E. Based on your answers from Parts A-D, use your understanding of interaction strengths and energy to explain how your evidence (interactions before/after solution) supports your claim (ΔH). (This is your reasoning.)
