I though I could but nothing I can come up with gives me a ratio of 0.663 :mad:

Well if we used 2.00 moles of SO2 to start then: 1.326 moles of SO2 0.674 moles of SO3 at equilibrium

Homework Statement For the reaction: 2SO3(g) →2SO2(g)+O2(g) when 2.00 mol of SO3 is added to a flask at 10.0 L and 350 K at fixed volume, at equilibrium the ratio of SO2:SO3 is 0.663. What is the values of the equilibrium constant? What is ΔG° at this temperature? Homework Equations...

Homework Statement Calculate ΔU when 1.00 mol of H2 goes from 1.00 atm, 10.0 L, and 295 K to 0.793 atm, 15.0 L, and 350 K. Homework Equations ΔU = q + w q=mcΔTThe Attempt at a Solution From the moles of H2 we can get the mass of H2 and use q=mcΔT. 1.00 mol H2=(2.0158 g H2/1 mol H2)=2.0158 g H2...

The gap from when the electron leaves the B field to the cup is 25 cm, its in the diagram. T is the period. I don't think the radius and arc length are needed.

I have attached a diagram of the problem.

Homework Statement A time t = 0 an electron enters a region of uniform magnetic field B = 0.010 T and has kinetic energy of 6.40E-16 J. It goes through a half-circle, exits the field and then accelerates across a gap with a potential difference of 2000 V, increasing in speed. It then hits a...

I have used Wolfram to solve some simple systems of equations involving x and y. I am not sure where to begin with something like this.

Homework Statement I need to come up with a formula to solve for i2 given the diagram of the circuit attached. I can identify 2 junctions and 3 loops. Homework Equations *The algebraic sum of the currents into any junction is 0. By convention the currents entering the junction are positive...

I honestly don't know. They used surface potential in the question and I assumed it to be electrical potential of the surface of the cylinder. I guess I am inadvertently suggesting there are two different potentials but only because the wording of the question has steered me in that direction. I...

For an upcoming lab I will be mapping out the equipotential lines in an electric field with an isolated conductor in it. The conductor is a hollow cylinder. I have attached a crude paint drawing of the apparatus. The lab asks some qualitative questions that I would like to knock out before hand...
