A) Idiots riot when they realise that the world is perfectly fine

B) Idiots start doing stupid things in anticipation of their alleged looming death

C) Kid in America farts, increasing world methane levels by 69%, leading to a series of undesired natural phenomena

D) Yahoo answers crashes for the nth time due to the unsustainable levels of idiocy arising

E) Sgt. McGee divides the imaginary number by a parabola

Mg(OH)2 + 2HCl -> MgCl2 + 2H2O

Al(OH)3 + 3HCl -> AlCl3 + 3H2O

Given that Mg(OH)2 and Al(OH)3 share different cations and that Al(OH)3 has an extra hydroxide ion, how will their reaction rates differ from each other?

It's pretty easy to prove the equation by changing the right hand side but I want to know how to approach the question if it is only the left hand side which can be altered.

Is this true?

(d/dx)v=dv/dx

If interest rates fall then banks collect less revenue from mortgage payments so shouldn't their profit decrease? I am confused .sadface.

For

Cu(2+) + 2e(-) --> Cu E=+0.34V

Does this mean the reaction requires 0.34V of energy to occur?

When you stretch an elastic rope and let go it immediately snaps to its rest position. Is this due to the particles within the rope attempting to maintain equilibrium with each other so the rope shortens to its original length in order to achieve this?

I'm not looking for an answer revolving around action and reaction forces.

Sources are good.

Find ∫y with respect to x if

dy/dx + y/(x^2+6) = 12

Let's say there are two blocks on a frictionless surface. One is about to collide with the other stationary block in what will be an elastic collision.

When they collide, is the energy transfer from the moving to non-moving block instantaneous and will it concentrated in the non-moving block's centre of mass?

Sources are good.

If I have

(Linear Function)/(Quadratic Function)

Would my final answer be

k/(Linear Function) where k is a constant

Need some difficult questions in preparation for an exam. Solubility equilibrium questions also accepted. Only exception is questions which revolve around pH.

I'm mainly after ones which take at least 10 minutes to complete and require some thinking. Please include the answer as well. Thanks.

I have a list of numbers in column A. Let's say those numbers are 5, 10, 15, 20 in cells A1, A2, A3, A4 respectively. In column B I need to add the square of it's cell A counterpart plus all the squares of the numbers before it ('it' being the cell A counterpart).

B1 would be "=A1^2"

B2 would be "=A1^2+A2^2"

B3 would be "=A1^2+A2^2+A3^2"

B4 would be "=A1^2+A2^2+A3^2+A4^2"

Now I have a lot more numbers in column A than just those 4 so I need a formula which I can copy over to the rest of column B. Any ideas?

Please don't just say the number of protons without giving an explanation. Also don't say the position on the periodic table.

I'm pretty sure someone thought "Hey elements aren't defined by their atomic weight! But rather their atomic number!" Who was the one that suggested this theory?
