A reaction vessel contains 8.06 g of H2 and 64.0 gof O2 at a temperature of 125?C and a pressure of 125kPa .
What is the volume of the vessel?
The hydrogen and oxygen are now ignited by a spark, initiating the reaction 2H2+O2?2H2O.
This reaction consumes all the hydrogen and oxygen in the vessel. What is the pressure of the resulting water vapor when it returns to its initial temperature of 125?C?
A proton is initially at rest at a point where the potential is 515V. Sometime later the proton is at a point where the potential is 190V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy.
Consider an equilateral triangle 12cm on a side. If a charge of 6*10^-5 C is placed at each vertex, find the force on the top charge.
What speed limit should be posted for the curve. How long (in {rm ns}) does it take light incident vertical to the glass to pass through this 9.0 {rm cm}-thick sandwich.
