Question 1 (1 point) 4) Listen The vapor pressure of liquid chloroform, CHCl3, is 500.0 torr at 25.1 °C and 300.0 torr at -7.4 °C. What is the AHvap of chloroform? In (P). -AHvap = - (1/12 ); ; R = 8.314J/mol*K R T₂ K = °C + 273.15 24.27 kJ/mol 102.3 KJ/mol 10.36 kJ/mol -10.36 KJ/mol

KUTSLIV pu Listen Calculate the total quantity of heat required to convert 36.4 g of liquid CCl4 (1) from 30.0 °C to gaseous CCl4 at 75.6 °C (the normal boiling point for CCl4). The specific heat of CCl4 (1) is 0.857 J/(g*°C), its heat of fusion is 3.27 KJ/mol, and its heat of vaporization is 29.82 KJ/mol. CCl4 MW = 153.82 g/mol q=m. C. AT q=m. *AHvap or q = m . AHfusion 0 10 a

Question 3 (1 point) Listen ▶ Choose the water with the lowest viscosity. O at 50 °C at 25 °C O at 45 °C O at 30 °C at 10 °C 身
