Ahh never mind I figured it out. Thanks.

Ohhh ok I see, thanks

How would I do that? I tried an ICE table but I don't have the value for the equilibrium constant -----------N204------------2 NO2 I -------(1.0 mol)---------(0 mol) C ---------(-x)---------------(x) E-------(1.0 - x)------------(x) So I'm stuck

1.0 mol of N2O4 placed in a constant pressure vessel at P = 1bar and T = 298 K. The system is allowed to slowly (reversibly) come to equilibrium. Given gibbs energy of formation, enthalpy of formation and entropy (the values are below) calculate the entropy change to the surroundings. N2O4...

so then Ao = A (1-e^-kt) Ao/A = 1-e^-kt ln (Ao/A) = +kt but I still get the same answer??

Homework Statement Geologists are able to calculate ages of rock samples through measurements of certain isotopic rations combined with known radioactive decay rates (all such decays being considered to adhere to 1st order kinetic rate laws). Two such processes leading to stable isotopes are...

I was just accepted into UofT Missisauga for social sciences instead of Life Sciences, which is what I applied for. Does anyone know If I can switch to another program before school starts?

So: R = (1000x)(2000 - 5x) then Profit = Revenue - Cost P = (1000x)(2000 - 5x) - 15 000 000 +1 800 000x + 75x^2 and P' = 200000 - 10150x x= 19.704 #of units = (1000x) = (1000)(19.704) = 19704 units which was the answer in the back of the book Thanks for the help!

So does that mean I should multiply 2000 - 5x by x to represent the number of units?

Homework Statement Through market research, a computer manufacturer found that x thousand units of its new laptop will sell at a price of 2000 - 5x dollars per unit. The cost, C, in dollars of producing this many units is C(x) = 15 000 000 +1 800 000x + 75x^2. Determine the level of sales that...

Ohhh I see! Thanks for the help!

Homework Statement Determine the equation of the plane that passes through (5,-5,5) and is perpendicular to the lines of intersection of the planes 3x-2z+1=0 and 4x+3y+7=0Homework Equations Ax+By+Cz+D=0 The Attempt at a Solution I found the cross product of the normals of the planes given...

Oh oops. Sorry about that I let x be 0, 1, and -1 and ended up with the equations -A-C=0, 4A+4B+4C=24 and -8A+8B-8C=-68. Then I used equation 1 and 2 to solve for B . I got B=6 but in our textbook (nelson calculus and vectors 12) it says that B=2. I'm also not sure how you would solve for A...

The original equation was: (11x^2-14x+9)/[(3x-1)(x^2+1)] = (A)/(3x-1) + (Bx+C/x^2+1) and I ended up with: 11x^4+19x^3-33x^2+27x = 3Ax^3-Ax^2+3Ax-A+3Bx^4-Bx^3+3Bx^2-Bx+3Cx^3-Cx^2+3Cx-C I wasn't sure what to do after that.

Calculus Homework Help! Homework Statement Determine the values of A, B, and C if the following is true: 11x^2-14x+9/(3x-1)(x^2+1) = A/3x-1 + Bx+C/x^2+1 (Hint: Simplify the right side by combining fractions and comparing numerators)Homework Equations NoneThe Attempt at a Solution I'm...
