The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and inversely proportional to the concentration of chemical B present. If the concentration of Chemical B is increased by 100 percent, what is the percent increase/decrease in the concentration of chemical A required to keep the reaction rate unchanged?

ok, i need help with a problem for science that i cant seem to get the right asnwer for.The question was....suppose you had as many sheets of paper as you had atoms in question 3 (which was 9.970625 x 10^23). If each sheet of paper had a thickness of .1 mm (1 x 10^ -4 m), how high in meters would your stack of papers be? Thank you so much in advance if you actually take the time to help me with this.

determine whether f satisfies the conditions of the mean value theorem on the interval [-1,2] and if so find the values of c guaranteed by the theorem.

f(x)=
2+x^3 , x 3x, x>1

(i did f(2)-f(1) over -1-2 = -7/3=3x^2.....c=sqrt7/9????)

1. An important difference btw. detergents and soaps is that soaps can be used in hard water.
2. Salts are made from bases, and esters come from alcohols that are also bases but have a hydroxyl group.
3. Polyesters are synthetic fibers that are made from an organic base that has two -COOH gruops and an acid that has two -OH groups.
4. Titration is a process in which a solution of an unknown concentration is used to determine the concentration of another solution.
5. The endpoint of titration occurs when a drop of base turns the acid solution pink but the color changes back again.

and explain the steps on how to get the answer.
(the letters are variables)


1) 2y+18 = 12-6(y+7)

2) 2(9x - 1) = 99-7(3 - 4x)

3) -x - (13 + 4x) = -3(5 - 9x) +2


thanks guys :)

I came home from work today and to my surprise there were hundreds, maybe thousands of lady bugs climbing all over my house. Then I walked inside and they're all over the inside too! How did they get in and why did they pick my house?

Sure they might have evidence and everything, but aren't they wrong sometimes? For example, if they've never dug down to the core of the earth, why should we believe then when they say there is one? Should we trust scientists, or our own beliefs??
