ANSWER 6 : (E) solubility of NaCl is least affected by the temperature. Solubility of NaCl is 39g/100g water at 100 degree celsius and 36g/100g water at 20 degree celsius. It shows that solubility of NaCl is really less affected by temperature. When temperature increases , NaCl shows very little variation in solubility. For other compounds variation is high. Actually there is no any specific formula to find variation in temperature. For this you would gave to take the help of chart which shows solubility of compounds versus different temperatures. And only by chart you will be able to know the variation because there is no any concept to find variation.

How am I supposed to know what C is for this problem? I have read in the solution manual that C = 0.449 J/goC but I don't understand how to get that number if it's not given to me in the word problem. I know how to solve the problem to get the answer for the final temp, I just don'r understand how to get the 0.449 J/goC. The word problem is: An iron nail with a mass of 12...

explain your answer, how do I know if it rises or falls?
Hypothetical elements A2 and B2 react according to the following equation, forming the compound AB. Az(aq) + B2(aq) 2AB(aq); AH = +271 kJ/mol If solutions Az(aq) and B2(aq), starting at the same temperature, are mixed in a coffee-cup calorimeter, the reaction that occurs is a exothermic, and the temperature of the resulting solution rises. b endothermic, and the temperature of the resulting solution rises. c endothermic, and the...
