if you burn 10.00g of octane. if the temperature is 500K, and you have an expansion of 1.00 atm, how much work in joule can be done by the system if the octane is completely converted to CO2 and water vapor? what will be the enthalpy change?
Explain why a mercury-in-glass thermometer with a uniform-bore capillary that is correct at 0 celsius and 100 celsius read 49.9 celsius when the temperature is actually 50 celsius.
The reaction: 2 HI → H2 + I2, is second order and the rate constant at 800 K is 9.70 × 10-2 M-1 s-1. How long will it take for 8.00 × 10-2 mol/L of HI to decrease to one-fourth of its initial concentration.
Determine Ssys separately for the volume and temperature changes and show that ?Ssys = 0 for a reversible adiabatic process. If the expansion had instead occurred irreversibly against a constant external
Calculate the molarity of a solution made by adding 27.8 mL of concentrated hydrochloric acid (37.3 % by mass, density 1.19 g/mL) to some water in a volumetric flask, then adding water
