Question 18: What is the correct answer for this? Question 18The dissolution of NH4CI in water is an endothermic process. If the initial temperature of water is 25°C, what is the expectedfinal temperature of the aqueous system?lower than 25°Chalf of 25°CC higher than 25°C(D) still 25°CQuestion 19In a constant-pressure calorimetry experiment, Jiwon and Jisun dissolved 10.0 g of CaCl, (MM = 110.98 g mol) in 250.0 g ofwater initially at 20.00°C. As the solid dissolves in water. the temperature rises to 26.73 C. Calculate the enthalpy ofdissolution (AH issolution) of CaClz in k) mol. Assume that the calorimeter absorbed a negligible amount of heat.+7.04 kJ mol

There are two types of processes generally known to us:- a)Endothermic Process b)Exothermic Process

Question 18 The dissolution of NH Cl in water is an endothermic process. If the initial temperature of water is 25°C, what is the expected final temperature of the aqueous system? lower than 25°C half of 25°C C higher than 25°C still 25°C

Question 18 The dissolution of NH Cl in water is an endothermic process. If the initial temperature of water is 25°C, what is the expected final temperature of the aqueous system? lower than 25°C half of 25°C C higher than 25°C still 25°C
