Question

For the substance with the phase diagram shown here, what temp will liquid & solid be in equilibrium when the pressure is 30 atm? What accounts for ideal gas law? Consider TWO IDENTICAL flasks, one containing CH_4(g) and the containing O_2(g) Both Flasks are a 0^degree c and 4.0 atm The Density of the gas in the flask CH_4 is____the flask with O_2 automobile is to be filled 18.0L Nitrogen gas 1.00 atm and 27^degree c what mass of NaN_2 must be decomposed? 2NaN_2(s) rightarrow 2Na(s) + 3N_2(g) A 2.0L ballon contains He gas a) a pressure of 1.0 atm As the ballon rises in the atmosphere its volume increases to 2.2L and its pressure decreases to 0.75 which statement is most correct? A. The density of the gas in the balloon increases B. The temperature of the gas in the balloon decreases C. the change of pressure in " " is directly proportional to the change in volume D. the average kinetic energy of the molecules in the balloon remains constant.

Explanation / Answer

33) Temperature when pressure is 30 atm,

(B) 0 oC

34) Ideal gases,

(D) neither I nor II

35) From the given data, the density in flask with CH4 is --- than O2 flask

(C) is greater than

density of gas = Pressure x molar mass/gas constant x temperature

36) moles of N2 = 1 x 18/0.08205 x 300 = 0.7313 mol

mass NaN3 needed = 0.7313 x 2 x 65/3

(B) 31.7 g
