Give only typing answer with explanation and conclusion 4. A chunk of dry ice, CO2(s), weighing 3.5 g is sealed inside a 2.0 L soda bottle initially containing 1.0 bar of air. What is the total pressure in the bottle after the dry ice sublimes and comes to 298.15 K? Enter the value with the appropriate number of significant figures. ⓘ bar
For the reaction shown, calculate how many moles of each product form when the given amount of each reactant completely reacts. Assume that there is more than enough of the other reactant. C3H8(g)+5O2(g)→3CO2(g)+4H2O(g) 1. 0.0558 molO2, v=?molCO2 2. 0.0558 molO2, v= ?molH2O
You perform a distillation at two different pressures like Jaren showed in the video.The first distillation was done on a day when the pressure was 760 mmHg. The boiling point (the range where we saw drips come over) was 72 oC. (This is the normal boiling point ) Then you connected the adapter to a vacuum. The manometer shows the pressure is now 250 mmHg. The liquid now boils at 50 oC. What is the enthalpy of vaporization in kJ/mol?Choose closest answer. 15.9 kJ/mol 46.8 kJ/mol 5.6 kJ/mol 24.9 kJ/mol8.8 kJ/mol 20.1 kJ/mol 89.2 kJ/mol

A student caried out this experiment and obtained the following data: Patm = 656.7 mm Hg Vinitial = 0.30 mL Mass of Alka-Seltzer sample = 0.123 g TH2O = 27.0°C Vfinal = 17.05 mL Determine the following: a. What is the balanced chemical equation for this reaction? (Hint: See Equations 1-4.) b. What is the vapor pressure of water? c. What is the partial pressure of carbon dioxide?
There are 1.07 X 10-3 moles of gas molecules contained in a CO2 cartridge under 5.0-atm of internal pressure. After several uses, the internal pressure is 3.4-atm. How many moles of gas remain in the cartridge? How much gas will remain in the cartridge when the internal pressure equilibrates to standard pressure? (Assume that the temperature and volume remain constant.)
