## Question

###### Specific Heat Capacity (C) The energy transferred as heat that is required to raise the temperature of gram of a substance by kelvin_m x Cp xATq= heat lost or gained m= mass of solution (grams) the Specific Heat Capacity of compound (Jllg x 'C)) Trnal - Teul AHsolution moles of saltIf 1,.25 g of ammonium nitrate (NHANOs) is dissolved in 25.0 mL of water, the following data are collected: starting temperature is 25 final temperature after dissolving is 21.9 "C. Calculate the enthalpy of

Specific Heat Capacity (C) The energy transferred as heat that is required to raise the temperature of gram of a substance by kelvin_ m x Cp xAT q= heat lost or gained m= mass of solution (grams) the Specific Heat Capacity of compound (Jllg x 'C)) Trnal - Teul AHsolution moles of salt If 1,.25 g of ammonium nitrate (NHANOs) is dissolved in 25.0 mL of water, the following data are collected: starting temperature is 25 final temperature after dissolving is 21.9 "C. Calculate the enthalpy of solution in Joules You may assume density of 00 glmL for the solution and you may assume that the specific heat is that of water (this is a dilute solution) and is 4.18 Ji(g*"C) Is this an endothermic or exothermic reaction? If 3.8 g of calcium chloride (CaClz) is dissolved in 100.0 mL of water; Ihe following data are collected: starting temperature is 25.8 'C final temperature after dissolving is 29.9 'C Calculate the enthalpy of solution in Joules. You may assume density of 1.00 glmL for the solution and you may assume that the specific heat is that of water (this is dilute solution) and is 4.18 JI(g* C) Is this an endolhermic Or exothermic reaclion?
