Question
Indicate your answer clearly 1) Which one of the following is a valid statement of Avogadro's law when temperature and pressure are constant? (2 Pts) 3) A real gas will behave most like an ideal gas under conditions of (1 Pt) A) high temperature and high pressure B) high temperature and low pressure C) low temperature and high pressure D) low temperature and low pressure A = constant B) = constant C) PV= constant D) V= constant × n E) V= constant × P 4) If pressure and temperature are kept constant, the reaction of 38 mL of Cl2 gas with 22 mL of CH4 gas via the equation: Cl2 (g) + CH4 (g) HCl (g) + CH3Cl (g) 2) A closed-end manometer was attached to a vessel containing argon. The difference in the mercury levels in the two arms of the manometer was 9.60 cm. Atmospheric pressure was 783 mm Hg. The pressure of the argon in the container was mm Hg. (1 Pt) mL of will produce a total of products. (2 Pts) A) 16 B) 30 C) 60 D) 38 E) 22 A) 96.0 B) 661 C) 773 D) 793 E) 882Explanation / Answer
2) Since it is a closed end manometer, the difference in height is same as internal pressure i.e. 96 mm of Hg.
4) 1 mol = 22.4 L
38 mL = 1.6* 10^-3 mol
22 mL = 9.82*10^-4 mol
here CH4 is limiting reagent.
since 1 mole of CH4 gives 1 mole of HCl and CH3Cl, from above conditions it will give 22ml of HCl and 22ml of CH3Cl.
total volume of reactants = 22+22 = 44 ml
