A student mistakenly uses 0.31g Mg. Will the temperature change of the solution be affected/ If so, will it be larger or smaller that it would be have been using 0.15g mg? Explain. The amount of heat released is (independent of the quality, a molar quality, depends on the temperature)
When working with molality, and no amount of solvent is specified, it may be convenient to assume Molality (m): Moles of solute per kilograms of solvent. Molality moles of solute kilograms of solvent You have 1 kg of solution. You have 1 kg of solvent. You have 1 L of solvent. You can never make assumptions about molality.

Which of the following is TRUE about solutions? Select one: please explain why true and why false Solute-solvent interactions will alwaysbe greater than individual solute-solute and solute-solvent interactions When solute-solute molecules are weakly bonded, the temperature of solution will decrease upon mixing Dissolution is favorable when solute-solvent interactions are stronger than solute-solute and solvent-solvent interactions. When solute molecules are strongly attracted to each other, ∆Hsolution> 0
