The melting of 0.140 g of Br2 (which occurs at -7.2 C at 1 atm pressure) absorbs 9.43 J of heat. Compute the enthalpy change in 2.00 mol of Br2 when it freezes.

equation of the tangent line is y-f(a)=f'(a)(x-a) in this case i am assuming your a=1 so your f(1)=8 to find f'(a) plug 1 into your derivative , It will be 2 y-8=2(x-1) now solve for y y=2x-2+8 y=2x+6 <-- y=mx+b form.

a) 1) take the derivative set it equal to zero and you will get critical pts 2)draw a number line and pick a point to the left and right of critical points 3) plug the selected points back into the derivative and if you get a positive number write down pl...

D^2=f(x)= (x-1)^2+((2x-4)-3)^2 f'(x)= 2(x-1)(1)+2(2x-7)(2) 0= 2x-2+(4x-14)2 0= 2x-2+8x-28 0= 10x-30 30=10x x=3 y=2(3)-4 y=2 (3,2) the square over D doesn't matter.
