Nope! It simply put Cl2/FeCl3. So if given that on a test it's best to assume only monosubstitution? Maybe noting possible disubstitution if more reagent is present?

Homework Statement Show the product(s) of chlorination (Cl2, FeCl3) of diphenylether Homework Equations None The Attempt at a Solution My solutions manual shows products with Chlorine in the para position, and then the ortho position, with a note saying (followed by disubstitution)...

1/349! So that is equal to d? I worked the problem out for \vartheta and I'm getting like .28, the multiple choice answers are 26, 40, and 33^{o}...

Homework Statement A grating with 349 lines/mm is illuminated with light of wavelength 412 nm What is the angular separation between the two lines formed in order m=2? Homework Equations \vartheta = m\lambda/d The Attempt at a Solution I did not know how to use this equation...

I differentiated x2+4y2\leq5 and got like dy/dx \leq -2x/8y and then I did not know how to continue. I looked up the problem online and found another way to do it that I am not sure if its right, the person who did this solution said that the shadow area had to be translated so he did like...

Homework Statement The figure shows a lamp located three units to the right of the y-axis and a show created by the elliptical region x2+4y2\leq5. If the point (-5,0) is on the edge of the shadow, how far above the x-axis is the lamp located? Homework Equations Implicit Differentiation...

Homework Statement Suppose that a competitive inhibitor of rubisco is introduced into chloroplasts. Which of the following statements is a logical consequence: (a) The light reactions will slow down, since electron carriers will be scarce. (b) The light reactions will speed up to drive the...

how do I factor x3+1...its not (x+1)3

Homework Statement Find the slope of the tangent line to the curve y=x3 at point (-1,-1) (i) Using Definition 1 m=limx-->a\frac{f(x)-f(a)}{x-a} (i) Using Equation 2 m=limh-->0\frac{f(a+h)-f(a)}{h} Homework Equations The Attempt at a Solution For the first one, I got as far...

Homework Statement 6CO2 + 6 H2O → C6H12O6 + 6 O2 Now suppose the above reaction is allowed to proceed in both directions, and has reached equilibrium. How would increasing the concentration of oxygen change the concentrations of carbon dioxide and sugar? Homework Equations The Attempt at a...

Homework Statement 6CO2 + 6 H2O → C6H12O6 + 6 O2 Homework Equations The Attempt at a Solution I believe that this is entropically and enthalpically unfavorable because the reaction is going to more order (synthesis of glucose) and heat is not being generated. Is my logic...

That's what I thought, I just wasn't sure if the ungiven volumes played a role. Thanks mgb_phys!

Homework Statement Two liquids of equal mass, one at 50 degrees Celsius, and one at 20 degrees Celsius, have different specific heats. Suppose the colder liquid has the higher specific heat. If the two liquids are mixed together in an insulating container, the equilibrium temperature of the...

Homework Statement If a temperature scale were based on the freezing point (5.5 C) and boiling point (80.1 C) of benzene and the temperature difference between these points was divided into 50 units (called X), what would be the freezing and boiling points of water in X? Homework...

Ah man I totally get it now. I wasn't thinking of the variable in the Volume formula as length, my book labels it as h, which I interpreted for height. Thanks so much edziura! That really helped me to clarify my thinking, all this stuff with mass is so difficult, its all over my homework...
