Question 7 At low temperature nitrogen dioxide molecules join together to form dinitrogen tetroxide. 2 NO2(g) + N204(9) (low temperature) A sample of NO2 sealed inside a glass bulb at 23 °C gave a pressure of 673 Torr. Lowering the temperature to -5 °C converted the NO2 to N204. What was the final pressure (in Torr) inside the bulb? Torr

A sample of gaseous PCs was introduced into an evacuated flask so that the pressure of pure PCI would be 0.48 atm at 433 K. However, PCIE decomposes to gaseous PCI; and Cly, and the actual pressure in the flask was found to be 0.80 atm. Calculate Ko for the decomposition reaction below at 433 K. PCI() = PCI;(9) + Cl2(0) Also calculate K at this temperature. At a particular temperature, 11.1 mol of SO3 is placed into a 3.8-L...
A mixture of dimethylhydrazine (CH3)2N2H2 (MM-60 g/mol) mixed with dinitrogen tetroxide (N204) are very effective rocket fuels. The reaction between the two reagents is give below: (CH3)2N2H2 (1)+2N204() 3N2(g) + 4H20(g) + 2C02(g) If 1.30 x 102 g of dimethylhydrazine reacts with excess N204 and the product gases are collected at 35°C in a 500 L tank. What is the partial pressure of N2 gas produced and what is the total pressure in the tank once the reaction is complete?
A pure solid sample of Substance X is put into an evacuated flask. The flask is heated at a steady rate and the temperature recorded as time passes. Here is a graph of the results: 190 150 temperature (°C) 110 heat added (kJ/mol Use this graph to answer the following questions: 150.0°C What is the boiling point of X? (check all that apply) solid liquid What phase (physical state) of X would you expect to find in the flask after...
Exactly 1.100 g of CO2(g) was introduced into a 1.00-L flask that already contained some O2 gas. The flask was warmed to 100 °C and the total pressure was found to be 815 mmHg. No chemical reaction occurred between CO2 and O2. Calculate the mass of O2 in the flask.

A 1.00 g sample of water is introduced into a 0.767 L flask containing some O2 gas. The flask is heated to 215.93 °C at which temperature all of the water is converted to the gaseous phase, giving a total pressure in the flask of 6.010 atm. 1. Calculate PH20 (in atm) in the flask at 215.93 °C. Report your answer to three decimal places in standard notation (i.e. 1.234 atm). 交答案 Tries 0/99 2. Calculate PO2 (in atm) in...
A 10.0 g sample of NH4Cl(s) is heated in an initially evacuated 5.00 L flask to 900 C. The solid ammonium chloride dissociates into NH3(g) and HCl(g) as products; reaction has Kp= 1.44 at this temperature. A). Calculate the partial pressures of NH3(g) and HCl(g) present at equilibrium. B). Calculate the number of moles of NH3(g) and HCl(g) that will be present in the flask at equilibrium. You may neglect the volume of the solid and assume V=5.00 L.
