Consider the formation of the three solutionsshown in the table. Type of Interaction Strength of Interaction
Solution A Solution B Solution C
solute-solute weak weak strong
solvent-solvent weak strong strong
solute-solvent strong strong weakRank the solutions A, B, and C from the most exothermic to the mostendothermic.
Rank the enthalpy of solution frommost exothermic to most endothermic. To rank items as equivalent, overlap them.
I don't have the textbook at thistime to look over the material to determine the answer, triedsearching the net but I was at no avail. Again, any help isappreciated.

This chart represents the melting point of several substance. what besy explains the high melting point of the salt?

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
