using k2=[H][CO3]/[HCO3]

when [CO3] and [HCO3] are held constant

There is a lot of talk about hydrogen fuel cells to help stop CO2 emissions in the atmosphere, but wouldn't releasing water vapor from hydrogen fuel cell cars on a grand scale be much worse for the environment because it blocks in much more sun light than CO2...about 25 times as much I think...something thats been puzzling me...does it fall into those solar windows or not?

The solubility product constant, Ksp, is 38.65

I see them every time we watch the Patriots and I have been wondering what they are...there is two of them around the 50

The formation of acid rain (H2SO4) from the oxidation reaction of sulfur dioxide gas (SO2) with OH in the atmosphere followed by the by the dissolution by rain droplets...

I came up with SO2 + 2 OH -> H2SO4

but wouldnt I have to include water as a product also because of the dissolution by rain?

so... SO2 + OH -> H2SO4 + H2O

But I cant get that to balance...myabe i did something wrong, please help me solve this

I know that they are equal I just dont understand how to explain this mathematically...could someone please explain this to me in that sense

Exercise 2 If A and B are matrices and AB is a 6 x 5 matrix, how many

columns does B have?

Exercise 3 If A and B are matrices and AB is a 4 x 7 matrix, how many

rows does A have?

Exercise 4 If A and B are n x n matrices, is it true that (A + B)^2 =

A^2 + 2AB + B^2? Why?

Stefan's Law of Radiation states that the rate of change in the radiation energy of a body is proportional to difference of the fourth power of the absolute temperature M of the surrounding medium and the fourth power of the absolute temperature T of the body. The rate of change of this energy is thus

dT/dt = k(M^4-T^4)

where k > 0 and the temperatures are measured in degrees Kelvin. If k = 0.05, the ambient temperature is 300 Kelvin, and the initial temperature of the object studied is 400 Kelvin, use Euler's method with h = 0.25 to approximate T(0.25), the temperature of the body 15 minutes later.

I dont fully understand the taylor approx from calc 3c...could you help me out with this problem...y'=t/y y(0)=1 at y(.5) and y(1) when h=.1

thanks work will help a lot...any little bit cause i have more problems involving this

im struggling with this problem so any help you can give me would be great...

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. There is no one around to help, so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. You pull up on the rope to lift the box.

What is the magnitude F of the upward force you must apply to the rope to start raising the box with constant velocity?

I got a new external wireless card for my computer, it is by hawkings technology and I do not know how to choose the network I connect to because it is connecting me to others wireless networks rather then my own...when I click view wireless networks, windows states that it cannot find wireless networks because I have another program enabled to manage them

Any help would be great

I love oranges, but I find I have difficulty peeling them with my hands most of the time. I was wondering if anyone has found a better way of completing this task, any input would help so much. THANKS!!!

He will probably go to the NBA next season, which team will he end up on?

Now that the brackets are up for basketball, who do you think it will be and why?
