Question

2. Dichlorine monoxide gas reacts with fluorine gas, F2, to give a new unknown gas that contains CI, O and F. In an experiment you find that 0.1552 g of the new gas has a pressure of 17.20 mm Hg and a volume of 1850.0 mL at 21.00 °C. a) What is the identity of the unknown gas? Explain your answer. Show all calculations. (a) Mass of gass = 0.15529 Pressure = 17.20 mm Hg = 0.02263 atm volume = 1850.50ml = 1.850 *L Temperature= 21.0°C = 21+273=294ks PV=nRT PV = (m/MRT M= MRT PV molar mass of the gas= 0.1552 X 0.0821 294 0-02263 X 1-850 = 89.48g/mol. b) Write a balanced reaction equation for the reaction of dichlorine monoxide gas and fluorine gas. reversible Foel (g) + Eetg) CIF (g) az Olgst F219) Dichlorine fluorine Monoxide gas 11.5 Chlorine opixoreoxrcer Monofluoride

Is this answer correct and whether the equation is balanced or not?

Answer 1

a) Volume of the gas, V = 1850 mL = 1.850 L Pressure of gas, P = 17.2 mmHg Temperature, T = 21°C+273 = 294 K Gas constant, R= 62.4 L.mm Hg K mol- According toi deal gas equation, PV = nRT PV No of moles of the gas, n = 10 RT (17.20 mmHg)(1.850 L) (6 4 L.mmHg (294 K) Kmol) = 0.001734 mol Mass of the gas = 0.1552 g _ 0.1552 g Molar mass of the gas = = 89.50 g/mol 0.001734 mol Since the calculated molar mass of the gas (89.5 g/mol) matches with the molar mass of the FC10, (86.5 g/mol), the identity of the gas is FC102 b) Equation : 401,0 + F, —→2FC10, + 301,
