Given:

Cu2O(s) + 1/2 O2(g) 2CuO(s) DH° = -144 kJ

Cu2O(s) Cu(s) + CuO(s) DH° = +11 kJ

Calculate the standard enthalpy of formation of CuO(s).

Long story, now I have a pet garden spider. What should I feed it? Do the bugs have to be fresh? Is there anything they eat besides bugs?

yes the world has gotten warmer - i am not convinced that we are the cause ( NATURE ! ) or that the change is long term ( on a global scale that could be a few thousand years lol )

BUT I AM SICK OF IDIOTS LINKING ONE SUMMER TO CLIMATE CHANGE !!!!!!!!

First, we know that girls require time and money, so:
girls = time x money

And we all know that "time is money," so :
time = money

Therefore:
girls = money x money

which means that:
girls= money^2 (money squared)

And because money is the root of all evil:
money = square root of evil

Which means that:
money^2=evil

And since:
girls= money^2

And:
money^2= evil

We can conclude that:
Girls = Evil

I have just been watching footage of two soccer stars who died instantly on the football pitch in 2004 and it took less than 2 seconds for them to die. Why does it happen so fast?

There are three problems that follow this, they are what needs to be solved. I am so confused. If you would like a link to the image of the problems instead than reading this, you can find the exact same information at the far bottom of the image here http://palcs.digitalschooling.com/brand/media/images/1193//Algebra_2/New%20Algebra%202/New%20Lessons/homework%20lesson%2012.JPG

Since you don't know whether X is positive or negative, you have to consider two cases: (part 1) X > 0 or (part 2) X < 0.

Part 1.) X > 0
Multiply both sides of the given inequality by 2x, which is positive.
10+x < 6x => 10 < 5x => 2 < x
In this case, the solution is x > 0 and x > 2, or x > 2.

Part 2.) X < 0
Proceeding as before, except that now 2x is negative, you have
10+x > 6x => 10 > 5x => 2 > x
The solution is x < 0 and x < 2, or x < 0.

[[[A / indicates a fraction]]]
Problem a.) 11/3 - 2/x > 5

Problem b.) 8/x - 7 < 9

Problem c.) 3/4 + 12/x-1 > 1




Thanks so much in advance.

An understanding would be great on how to solve a problem like this.

It has two parts (a, and b) to it.

a.) Suppose A and B are positive and A < B. Explain how you know that A^2 < B^2.

b.) Suppose you know that for two numbers A and B, A^2 < B^2. Does it follow that A < B? Discuss the different cases depending on which of the two numbers A and B is positive.


Thanks in advance, it means a bunch. (I am NOT just scrounging for answers, I would like an understanding, although answers would be extremely helpful to see how they are gotten. Thanks.)
