Question

QUESTION 33 Ar conditioners work by a compressor condensing a fluorocarbon of some type. When this liquid fluorocarbon returns from the condenser and passes over coils, it expands cooling the coils. The air passing over the coils cools down allowing us to be more comfortable. Determine the total energy change that results from boiling 19.8 ml of chlorodifluoromethane- a now banned substance due to its deleterious greenhouse effect - into a closed system at standard pressure and 29.8 °C. Information for chlorodifuoromethane (not all may be necessary). CHCIF2 • molar mass-86.47 g mol-1 density - 1.27 g ML" Boling point = 232.5K • Hvan 20.1 kJ/ mol Determine the total energy change, ink, into a closed syster you will need to determine the enthalpy change and work) (use three significant figures QUESTION 34 If two electrons in the same mom have the same value of they are in the same orbital in the same sublevel, but not necessarily in the same level. in different levels and in different shaped orbitals. in the same level, but different sublevel none of the above Click Save and submit to be und submit.

Answer 1

Valume of CHUF - 19.8 ml mass of Chur - density & Valume 25. 146.gm mals of CHUF₂ = mass 25. 196gm - 0.29 mal. malor mass 86.47gmat! a chur chuĄ (gas). after bollitong 0.29 mal of liquid converted into gos. Valume occupied by gaseous chuĄ at P= 1 atm T= 20.8 c = 302.8k n= 0.29 mal 0.29 X 0.08205 x 302.8 V = nRT 7. 21 AV -Vi = during boiling during bowling - Vevo 7.21 -0.0198 L - 7.24 Work done w - - POV P = 1 atm 5 - 1x7.2 = - 7.2 latm - - 7.30 Towe - 0.73 no Im - 101.325]}

All - Alvop x mol of Chur = 20.1 X 0.29 5.83 kJ an = aut pav. LU - au- PAV. AU = 5.83 kJ - 0.73 UT = 5.10 kJ. - l. at azimuthal two electron quantumn are in tell us same about orbital the orbital. then they have some value of ľ. In same orbital.
