19.265 g of pure liquid methanol at 22 °C is converted to gaseous methanol at 261 °C at constant pressure. The process occurs in three steps; one step in liquid state, and two steps in gaseous state. Methanol Data boiling point 64.6 °C Cgas 1.25 J/g °C molar mass 32g/mol Cliquid AHvap 2.14 J/g °C 35.27 kJ/mol With reference to the above data answer the following questions. A. The temperature change in the liquid state (step one) is: The mathematical operation for calculating the heat transferred (q.) during step one is: • Unit = 'b B. The mathematical operation for calculating the heat transferred (qa) during step two (at the boiling point) is: 4 = Unit C. The temperature change in the gaseous state is: The mathematical operation for calculating the heat transferred (q,) during step three is: • Unit D. Suppose that the heat transferred during each of the above steps is q̟ = 344 J, qa = 4-383 kJ, and q3 = 540 J The mathematical operation for calculating the total heat transferred (qtota) throughout the whole process is: Itotal =

Answer the following question

19.265 g of pure liquid methanol at 22 °C is converted to gaseous methanol at 261 °C at constant pressure. The process occurs in three steps; one step in liquid state, and two steps in gaseous state. Methanol Data boiling point 64.6 °C Cgas 1.25 J/g °C molar mass 32 g/mol Ciquid 2.14 J/g °C AHvap 35.27 kJ/mol With reference to the above data answer the following questions. A. The temperature change in the liquid state (step one) is: The mathematical operation for calculating the heat transferred (q.) during step one is: 41 = • Unit В. The mathematical operation for calculating the heat transferred (q=) during step two (at the boiling point) is: 42 = • Unit C. The temperature change in the gaseous state is: The mathematical operation for calculating the heat transferred (q3) during step three is: 43 = Unit D. Suppose that the heat transferred during each of the above steps is q̟ = 344 J, q2 = 4-383 kJ, and q = 540 J The mathematical operation for calculating the total heat transferred (qtotal) throughout the whole process is: 9total = Unit
