Calculate the Enthalpy of Solution for Calcium Chloride (110 $\to$ Ca²⁺(aq)+ 2 Cl^-(aq)

question 41

Short Answer

Calculate the enthalpy of solution for calcium chloride (110.98 g/mol)using the following data: When 37.73 g of CaCl₂ is dissolved in 240.00 g of water,the temperature of the solution increases by 24.25°C.Assume the specific heat of the solution is 4.18 J/(g . °C).
CaCl₂(s) $\to$ Ca²⁺(aq)+ 2 Cl^-(aq) $\quad$$\Delta$ H = ? kJ/mol

Definitions:

Cochlea

A spiral-shaped, fluid-filled inner ear structure responsible for converting sound waves into nerve impulses that are interpreted by the brain as sound.

Eardrum

A thin membrane that separates the outer ear from the middle ear, vibrating in response to sound waves and initiating the process of hearing.

Cochlea

A spiral-shaped, fluid-filled organ in the inner ear responsible for converting sound vibrations into nerve signals for hearing.

Sound Vibrations

Sound vibrations are the back-and-forth movement of particles when a sound is produced, traveling as sound waves through mediums like air or water.
