As we have discussed in class, CO is highly toxic. An added danger comes from the fact that CO is very slightly less dense than air, so it rises up from the malfunctioning furnace in the basement to the bedrooms upstairs... victims are poisoned while they sleep. Calculate the density of CO and air: assume 298 K and 1 atm (assume air is 22% O2, 78% N2). (Remember not to round anything until your calculation is finished.)
7. For an Ideal Gas, find the Partial Derivative of v, w.r.t. P. 8. Please consider large room that needs a new carpet. The vendor came and estimated the cost at $8 to $12 per square foot, depending on the condition of the sub-floor. The vendor then "paced off" the room and estimated that the room was 60° by 50’. You estimated that the vendor's method of measuring the room dimensions could be off by as much as 3' in for each dimension. Please find the (a) mean cost, (b) best case cost, (c) worst case cost, and (d) the most probable cost,
X Your answer is incorrect. "Strike anywhere" matches contain P4S3, a compound that ignites when heated by friction. It reacts vigorously with oxygen, as follows: P4S3(s) + 802(g) –→ P4010(s) + 3SO2(g) AH°reaction = -3,677 kJ Use data from the hint to determine AH°, for P4S3(s). i -1.54E2 kJ eTextbook and Media Hint Save for Later Attempts: 2 of 3 used Submit Answer
PROBLEMS (1 L atm = 101.325 J, 1 L bar = 100.000 J) 1. In an exothermic process, the volume of a system contracted from 3243 mL to 2087 mL against a constant pressure of 1.063 bar. During the process, 124.6 calories of heat energy were released. What was the internal energy change for the system in joules? 2. Calculate the change in internal energy for the thermal decomposition of 5.432 g of potassium chlorate at a constant external pressure of 1.634 bar. The decomposition reaction is 2KC1(s) + 3 O2(g) Potassium chlorate's heat of formation is -391.20 kJ/mol, potassium chloride's heat of formation is -435.87 kJ/mol, and oxygen has a density of 1.308 g/L at the reaction temperature. Recall that the enthalpy of a reaction can be determined by a summation of enthalpies of formation. 2 KC103 (5) A ΜΠΟΣ

Indicate the effect on the pressure of the following change. (Options: increases, no change, decreases) The volume and the Kelvin temperature are reduced by one-half (n constant). The temperature is doubled (V, n constant). There is a decrease in volume (n, T constant). Some molecules of gas are removed (V, T constant) A leak occurs and gas escapes (V, T constant). A leak occurs and gas escapes (V, T constant).
