D and 10) The normal boling point of a liquid is al the only temperature at which there carn b) the temperature above which the substance cannot exist as a c) the temperature at which gas d) the temperature at which the vapor be equiliterium between the liquid and gas states energy than molecules have ρresure equals 700 mmHg a consideration of the phase diagram below, a change from point M to point N comesponds to a) sublimation b) condensation c) evaporation d) freesing e liquefaction 12) All the following have noble gas configurations EXCEPT 3) The total number of valence electrons in ammonium tetrathionate, (NH)so a) 70 b) 72 c)76 d)78 e)80 a) 4 π bonds b) 3 n bonds and 10 bond bonds ) When a carbon atom has sp hybridization, it has: C) 2 π bonds and 2 σ bonds d)1nbond and 3 σ bonds e) 4 ) A given mass of gas occupies a volume of 4.00 L at 60"C and 550 mmiHg, Which of the following mathematical expressions would you use to calculate its pressure at 3.00 L and 30 c? a) 550 mmHg x (4.001/3.00L) x 30°C/60°C b)550 mmHg x (3.001/4.00L) x 30°C/60c c) 550 mmHg x (3.001/4.00L)x 333K/303K d) 550 mmHg x (4.00L/3.00L) x 303K/333 e) 550 mmHg x (3.001/4.00L) x 303k/333 sample of oxygen is collected Oerwater at a total pressure of 675 mmHg at 29C. The vapor ressure of water at 29'C is 30.0 mmHg. The partial pressure of the O2 is: 1.00 atmb) 0.955 atm c)0.849 atm d) 0.831 atm e)0.791 atm

Answer 1

water vapor Liquid may be present at following point : A.B.F.G Note: As image given is not clearly visible, I have changed notation for Point. 10) The normal boiling point of liquid is the temperature at which its vapour pressure is equal to 760mm Hg Option D At point M the state of water is liquid & at N solid therefore its frrezing process Option D 12) P3+ will have electronic configuration as: 1s2 2s2 2p6 3s-= [Ne] 3s2 therefore , P3+ is not noble electronic configuration. Option D
