" Write an alternate reaction that can be used to prepare the same product that we got in our lab ( changing the metal in the alkoxide or halide leaving group is not sufficient.) Explain the reaction you used, is it expected to be cheaper cost wise, and or produce a higher yield, based on the...

Problem: Block 1 is 7kg and is resting on a table with friction. Block 2.5kg is connected by a massless cord and is hanging over the side of the table. ( assume there is no friction on the cord where it goes over the side of the table.) The two masses are stationary but on the verge of...

[b]1. What are the radius and center of this circle? x^2+4x+y^2-3y=0 Homework Equations [b]3. Another question on my final review I don't recall exactly how to set up or what steps I need to do in order to solve this problem. Any help is appreciated

[b]1. What is natural Domain of Square root(x(5-x)) [b]2. [b]3. I know x can not make the square root equal zero, but I am not sure how to prove this algebraically. Any help would be appreciated, also what's the difference between natural doman, and Domain? My book doesn't explain this at all.

[b]1. Sqrt(x)+1=-2Sqrt(x-3) 1.) Sqrt(x)=-2Sqrt(x-3)-1 ( )^2 gives 2.) x= (-2sqrt(x-3)-1)^2 and here I think you need to attempt to foil but I am not sure how it works. (-2sqrt(x-3)-1)(-2sqrt(x-3)-1)=x 3.4sqrt(x-3)+2sqrt(x-3)+2sqrt(x-3)+1=x? Not really sure if...

[b]1. You wish to mix 10% acid solution with 24% acid solution to make 10 liters of 14% acid solution. How much of each do you use? [b]2. a(.10)+b(.24)=10(.14) ? I think the problem is asking for what a and b are , and both added together equal 10 liters at 14% acid solution. The only...

[b]1. Suppose y = bx^2 +cx + a a.) in terms of a, b, and c, what values of x make y=0? b.) if a=3.1, b= -2.2 and c=-4.3 evaluate those solutions to 3 significant digits: Homework Equations [b]3. I am not really sure how to solve for what the question is asking for in part...

[b]1. Here's a theorem about the tangent function. tan(x) = c iff 1: x = tan^-1*c or 2: x = tan^-1*c+n(180) for some integer n. Find a solution to tan x = 1 between 270 and 450 degrees. [b]2. [b]3. I am not really sure how to go about starting this problem. I have only two...

Fixed the problem, hope it clears any confusion. If not let me know.

[b]1. Solve algebraically for... 1.) 4x*(x^2-5)+(x^2-5)^2=0 two separate problems not relating to each other 2.) 4x^3*(1-x)^3-3*(1-x)^2*x^4=0 [b]2. this symbol ^ is to the power of. all x's are the x variable as written in my precalc book. For problem 1. I see that...
