C) the Na'ion will chemically bind to the water molecule. D) the Cl" ion will chemically bind to the water molecule. We were unable to transcribe this image
Please Explain Explain why a) solute-solute, b) solute-solvent, and c) solvent-solvent interactions are important in determining the extent a solute dissolves in a solvent. What is the relative importance of each of each factor listed in problem #1 when a) solids, b) liquids, and c) gases dissolve in water?
Choose all the answers that are true about water.? 1. Water dissolves substances that are polar (polar covalent bonds). 2. Water dissolves substances that are non-polar (non-polar covalent bonds) 3. water is an excellent solvent. 4. Water dissolves substances with ionic bonds, such as NaCl.
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) Na+ (aq) + Cl- (aq) What is the sign of the change in Gibbs free energy (DG) for each process in the forward direction?
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) --> Na+ (aq) + Cl- (aq) Consider the equation, DG = DH - TDS. For each dissolving process, substitute the signs of DG and DH into the equation and predict the possible sign(s) for the entropy (DS). Explain why you chose this sign(s). Does the sign for entropy change seem to make sense? Explain.
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) --> Na+ (aq) + Cl- (aq) Write ionic equations, similar to the one above, that describe how NaNO3 and NaCH3COO each dissociate as they dissolve in water. Include heat as a reactant or product in each equation.
When lithium fluoride dissolves in water, the temperature of the resulting solution decreases. This means that for lithium fluoride, the enthalpy of hydration is: the same magnitude as the lattice energy smaller(magnitude) than the lattice energy larger (magnitude) than the lattice energy
えー, 11. Explain in molecular terms the processes involved when a solute dissolves in a solvent. Pay (2 pt) particular attention to the strength of forces involved in each process.
