A 24.798 g quantity of N,O4(g) was placed in a 1.586 L container at 400K. The chemical decomposes to an equilbrium mixture of N2O4(g) and NO2(g) that had a total pressure of 5 atm. What is the heat absorbed in kJ when the N2O4(g) decomposed. Standard heats of formation may be found in the appendix. Record your answer in kJ and with 3 decimals. Use 33.2 and 11.1 kJ/mol for the enthalpy of formation of NO2 and N204 respectively.

Try Again Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. -1 A 39.0 g sample of glass, which has a specific heat capacity of 0.670 J·g .°C¯', is dropped into an insulated container containing 200.0 g of water at 65.0 °C and a constant pressure of 1 atm. The initial temperature of the glass is 1.1 °C. Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water. Be sure your answer has 3 significant digits. 67.1 °C
A 56.2 g sample of aluminum, which has a specific heat capacity of 0.897 J-g¹C¹, is put into a calorimeter (see sketch at right) that contains 250.0 g of water. The temperature of the water starts off at 24.0 °C. When the temperature of the water stops changing it's 26.9 °C. The pressure remains constant at 1 atm. Calculate the initial temperature of the aluminum sample. Be sure your answer is rounded to the correct number of significant digits. °C X Ś thermometer- insulated. container water sample a calorimeter
Propane gas (C3H6 (g)) is withdrawn from a 100.0 L cylinder at 25.0 oC and is burned at constant pressure in an excess of oxygen. The pressure in the cylinder falls from 2.25 atm to 1.05 atm. The liberated heat is then used to raise the temperature of 65.5 L of water from 25.0 oC to 56.7 oC. What % of the heat of combustion was absorbed by the water (d = 1.00 g/mL)? Specific heat capacity of water = 4.18 J/g/oC Δ Hfo(H2O(l)) = -285.8 kJ/mol, Δ Hfo(O2(g)) = 0 kJ/mol, Δ Hfo(CO2 (g)) = -393.5 kJ/mol Δ Hfo(C3H6 ) = -103.8 kJ/mol

A chemical engineer studying the properties of fuels placed 1.300 g of a hydrocarbon in the bomb of a calorimeter and filled it with O₂ gas. The bomb was immersed in 2.550 L of water and the reaction initiated. The water temperature rose from 20.00 °C to 23.55 °C. If the calorimeter (excluding the water) had a J .)
